Available with an FM approved and an ATEX/IECEx compliant transmitter design, the rugged FCX80 Analyzer configuration is certified for hazardous locations where combustible gases can be present in water treatment areas. This rugged transmitter design helps prevent hazardous situations that could jeopardize employee safety, equipment and the surrounding area.  Such gases have been responsible for serious accidents causing loss of life and facility damage.

Highly dependable, the precision FC80 Analyzer Series monitors free chlorine in drinking water from 0.05 – 20 ppm chlorine as the standard range or 0.01 – 5.00 ppm with the low range sensor. The FC80 is compliant with EPA method 334.0 for measuring drinking water.  It also supports industrial applications: rinse water, cooling water or other fresh water sampling.

A complete measurement solution, everything needed to do the job comes with the FC80 family’s complete panel mount design kit, incorporating a constant head flow control device, the S80 or S88 pH sensors, the chlorine sensor and ECD’s T80 analyzer/transmitter. Connect the sample and drain lines, connect the power and outputs, and it is ready to use. Calibration is accomplished by DPD comparison.

ECD’s FC80 Analyzer Series with its smart digital design features an amperometric sensor.  This sensor measures only the hypochlorous acid component of the free chlorine sample and the analyzer calculates the balance using either the measured pH or a user defined fixed value.  The pH sensor provides accurate compensation for samples between pH 6 and 9, thus eliminating expensive sample conditioning systems to control the pH of the solution.

Users will find the free chlorine necessary for disinfection exists in solution as a pH dependent ratio of hypochlorous acid (~100% at pH 5) and hypochlorite ion (~100% at pH 10).  Chlorine has been a popular disinfectant for water treatment to ensure public health.  Disease causing organisms such as Cholera, Hepatitis A, Typhoid Fever and Dysentery are eliminated with Chlorine, along with slime bacteria, algae and molds that can grow in water storage facilities such as reservoirs and storage tanks.

Over the past decades, there have been several other methods developed to measure chlorine in drinking water applications.  Colorimetric systems, for example, have been popular, but require the use of reagents that must be replaced monthly in order to ensure accurate measurement.  With its amperometric sensor design, the FC80 eliminates the need for expensive reagents and offers an economical operating cost for municipal water districts that must manage tight budgets.

The go-anywhere FC80 Analyzer is available with either 110-240 VAC or 24 VDC power.  Its highly intuitive user interface parameters can be graphically displayed with user defined line, bar or gauge style graphs. The standard configuration has two 4-20 mA outputs, three alarm relays and a MODBUS RTU.

Ideal for dirty or nutrient-rich environments, the FC80 is available with an Auto Clean option that includes a solenoid actuated spray cleaner using either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle.

A major challenge in milk processing is the large number of deliveries and production batches due to increasing product diversity. “We process different qualities of milk and attach greatest importance to purity in origin and sorting ,” says Mr. Kuhn. The final stage in every delivery of raw milk by the company’s own milk tankers is cleaning. This means 30-40 CIP objects every day. The great number of production batches entails numerous cleaning cycles, since prior to processing any new batch, lines and tanks must be clean and hygienic. Right on the shop floor, Mr. Kuhn’s team runs 30-40 CIP cleaning cycles every day in order to prevent any standstill in milk processing. “No CIP cleaning means no canning,” he says, describing the central role of cleaning-in-place. This must not happen, he says, since constantly milk tankers are arriving at the yard, filling the raw milk silos which are as high as a house

Reliable conductivity measurement is required to make sure CIP cleaning does not block production. Conductivity measurements monitor the concentration of acids and alkalis for the maximum cleaning effect and will also detect when the pipe is flooded with pure again at the end of a CIP cycle. Conductivity sensors play a crucial role also in phase separation. They identify different media and allow for collecting used fluids to re-enter another cycle and this way play an important role in saving resources.

When Mr. Kuhn took over his position as Manager Electrical Engineering in the Thalfang company eight years ago, he quickly realized that the sensors used for conductivity measurement did not meet his high expectations. But even test runs with alternative sensors did not present Mr. Kuhn with the desired results. He wanted the optimum solution for conductivity measurement and kept searching.

In the end, the experienced Manager encountered the conductivity sensor he was looking for by chance. At some point, a third-party labeled CombiLyz AFI4 ended up the workbench of the electrical maintenance department. Since the dealer didn’t answer the service request, an employee made investigations to find out the manufacturer of the promising sensor – Baumer. Now the sensor partner for conductivity measurement was found. “After the successful test run we were pleased with the performance of the conductivity sensor, since AFI4 met our needs just as required,” reports Mr. Kuhn. In addition, he was well satisfied with the customer service provided.

Reliability is first among technical requirements. AFI4 proves itself every day in up to 80 CIP cleaning cycles. Since having started the cooperation with Baumer four years ago, there had not been a single failure of the AFI4s in use, neither there was a single housing damaged or leaking. “I’m satisfied by an analytical sensor working well for five years. That’s why we are on the right track with the Baumer sensors,” says Mr. Kuhn.

Another requirement were short response times with high precision measurements in parallel. In this point as well, AFI4 scores high by very good performance: “AFI4 is very fast and is exactly what we need since we deploy the sensor also in phase separation.” To him, this is the most important point. With flow volumes of 4-6 liters per second, fast measurement results will noticeably increase resource efficiency. Mr. Kuhn nods, “Thanks to AFI4 we minimize product rejects.” This is also to the benefit of the agricultural shareholders since besides quality, factory efficiency is decisive in raw milk processing. After all, it is the factory objective to make the most of the milk supplied by their member dairy farmers.

Can AFI4 guarantee such high long-year performance despite the high requirements? At Hochwald Foods, there are no signs at all of any performance loss. The technical team checks each sensor once a year. Out of the 47 currently deployed AFI4 sensors, a mere two presented drift but even within the tolerances. “The long-term stability is very good,” says Mr. Kuhn. According to him, further AFI4 benefits are the rotatable touch color display, easy handling, compact design, switchable measuring ranges and adaptive connection system. “In addition, this Baumer sensor is freely configurable and hence allows for universal use in every application. This also simplifies and reduces spare part inventory,” adds Mr. Kuhn who is a strong supporter of standardized solutions.

As a result of the good experience made with AFI4, the Manager of Electrotechnical Engineering has declared the robust Baumer sensor as a factory standard. For the upcoming factory overhaul with 6 new CIP circulations, this means: The long-term stable Baumer analysis sensor will continue to make an important contribution towards smoothly running milk processing. For optimal process monitoring, AFI4 will get company and backup by the proven Baumer PF20 flow sensor measuring flow velocity in CIP returns. This will further assure product quality and prevent time-consuming troubleshooting in the pipe system. Since after all, non-stop milk processing must be ensured in the future.

INFO Box

Hochwald

Hochwald Foods GmbH is a subsidiary of Hochwald Milch eG (both locations in Thalfang/Hunsrück) with 3082 member dairy farmers, an annual milk volume of 2.17 billion kg and 1.59 billion Euros annual turnover. The cooperative dairy company employs 2065 people at eight plants for dairy products such as cheese, yogurt, cream, and mixed milk drinks. The Thalfang factory founded in 1932 has specialized in condensed milk. Every day, 800,000 to 1.3 million kg of raw milk are processed into condensed milk and canned by 190 employees. The best-known brands rolling off the line include Bärenmarke and Glücksklee, together with other brands intended for the international market. 98 percent of the cans produced in Thalfang are exported, mainly to North Africa, the Middle East and South America. “In hot countries, non-perishable condensed milk is very popular. Less for coffee, though, but as consumer milk or in tea,” says Mr. Kuhn, Manager Electrical Engineering at the Thalfang factory.  

Why is AFI4 that robust and fast?

The Baumer CombiLyz AFI4 conductivity sensor is popular in food & beverage applications thanks to its durability and speed. One of the reasons for such high robustness is the one-piece design: unlike conventional conductivity sensors, sensor tip and temperature element are entirely in PEEK. Omitting a metal component with different thermal expansion, the sensor tip will endure frequent temperature jumps. Furthermore, thanks to the one-piece design Baumer was in a position to realize outstanding fast 15 seconds as temperature compensation time t 90. This design has been created by the Baumer experience in hygienic ultrasonic welding which is applied in the manufacture of the AFI4 sensing tip. The dark thin line around the opening in the sensing tip gives evidence of such excellence in welding. All welded products undergo helium leak tests. Like many other Baumer sensors, the AFI4 comes with EHEDG certification.

ECD’s intelligent TC80 Analyzer eliminates consumables, simplifies installation and reduces maintenance with a self-cleaning design to lower the total cost of instrument ownership over its long life. This versatile, easy-to-use analyzer is a panel-mounted unit that is ready-to-go right out of the box. It is also fully compliant with the U.S. Environmental Protection Agency’s (EPA) Method 334.0.  

Ideal for measuring total chlorine, the TC80 Analyzer’s Cl₂ sensor is a precision three-electrode amperometric type design, which measures all chlorine species in the water, combined chlorine and free chlorine. It is available in either: (1) a standard high-range configuration measuring Cl₂ from 0.05 to 20 ppm or (2) a standard low-range configuration of 0.005 to 2.000 ppm. This analyzer comes factory pre-calibrated to the chosen measurement range before shipment, which also speeds set-up.

Total chlorine is defined as the combined amount of free chlorine, chloramine, organic and bound chlorine in a water sample. The TC80’s Cl₂ sensor is a three-electrode amperometric sensor with a gold cathode, silver halide anode and 304 SS counter electrode. The TC80’s built-in pH sensor provides accurate compensation for samples between pH 4 and pH 12, eliminating the need for expensive sample conditioning systems to control the pH of the solution.

The TC80 Cl₂ Analyzer is a complete solution requiring no additional third-party components.            

Everything needed comes in one box from ECD and is assembled on a panel mount board.  The plumb-plug-and-play design incorporates a flow control device, the pH sensor, the chlorine sensor and the highly intelligent T80 transmitter, which are all conveniently mounted on the instrument’s ready-to-mount PVC panel. 

Installation is simple: There is no special technician training or tools required for installing the TC80 Cl₂ Analyzer.  Technicians simply connect the sample and drain lines, connect the power and outputs and the analyzer is ready to use.  The analyzer’s amperometric sensor technology and automatic pH compensation keep the cost of ownership low by requiring no inventory of expensive reagents on a shelf, tracking/ordering of reagents or valuable technician labor time to replace them.

Featuring an automatic flow control and large flow tubes and cells, the TC80 Analyzer greatly reduces clogs and blockages, which are a common problem in other total chlorine analyzers and allows for easy cleaning. It also can be ordered with an auto cleaning option to keep the chlorine sensor clean from water contaminants for an extended period of time.  This useful time scheduled pressure-spray washer keeps particles from adhering and building up on the sensor.

For user flexibility, the TC80 Cl₂ Analyzer is available with either 110-240 VAC or 24 VDC power. The TC80 graphically displays both the total chlorine and pH levels, which supports easy trend analysis. The standard configuration has two 4-20 mA outputs and three alarm relays, 24 VDC or 110/220 AC power.  

TCV80 Analyzer users will appreciate the choice of MODBUS and/or HART communication that is available when ordering.  Both digital bus communication options report Cl₂ analysis data directly to automated process control systems that can adjust Cl₂ levels in the process stream according to real-time conditions.

• Real-time monitoring with GEA NiSoMate: Continuous inline control of the consistency and
  quality of liquids during the homogenization process
• Early detection of potential quality problems allows immediate intervention to minimize waste
• User-friendly interface: Intuitive operation and easy-to-understand data visualization for
  simple integration into existing production processes

Comprehensive solution for measuring all parameters

The GEA NiSoMate inline quality monitoring system combines dedicated, perfectly matched sensors. These are bundled in a single unit that is installed directly on the homogenizer. With highprecision measurement accuracy, the homogenization effect on the respective liquids can be displayed in real time without touching the product. The sensor system employs an ultrasoundbased “beamforming array” technology that was specially engineered by GEA homogenization experts for this purpose. The system allows physical product properties such as density, consistency change and dilution to be derived. These parameters can be read by an external process control which can then take appropriate actions. Consequently, operators can monitor the process directly on the production line and adjust the performance of the system accordingly, without having to wait for laboratory samples results. The GEA NiSoMate also eliminates unnecessary detours, product waste or over-setting of high pressure, resulting in significant overall resource savings.

A booster for flexibility

With the GEA NiSoMate, users can also achieve their overall production goals much faster, especially when processing new types of liquids. In addition, pre-configured recipes can be used and set for a faster process flow once an in-situ fingerprint has been analyzed for the respective starting product. This enables faster development of new recipes and therefore faster production of new products, offering a competitive edge, especially in food, new food and pharmaceutical applications.

Since the new technology combines several sensors in one system, it ensures a more accurate, reliable and robust product evaluation. The collected data can be transferred to existing monitoring systems and dashboards and used for further analysis and process optimization.

Appropriate modules have been predisposed in the system for the integration of AI, which in the future will allow self-optimization of the plant and process.

The GEA NiSoMate can be used in all GEA homogenizers – from laboratory units to large industrial plants – and is also available as a retrofit for existing plants.

Trade fair highlight: Expert lectures on the new system

Attendees at Anuga FoodTech can gain deeper insights into the new technology from GEA homogenization expert and Product Manager Annachiara Tonelli, who will discuss GEA NiSoMate in detail at 9:30 a.m. on Thursday, March 21, 2024, on the main stage of the trade show.

Different applications utilize different disinfectants. Ozone is a common disinfectant in water treatment applications since it is highly reactive. Water distribution networks rely on chlorine or chlorine dioxide because they have a deposit effect that ensures the water safely reaches the consumer. In terms of coolant applications, the water is frequently disinfected with chlorine dioxide or free bromine because they break down the biofilm directly and are effective across a wide pH range. Free bromine is employed as a disinfectant in seawater applications since the chlorination in this medium produces free bromine. Peracetic acid is commonly used in the food industry as it acts as a broad-spectrum disinfectant. Disinfection with free chlorine or chlorine dioxide is also used in the treatment of product water for the manufacture of soft drink beverages.

Ensuring consistent taste in the beverage industry

Raw water treatment plays a key role in terms of the safety and taste of the end product in beverage manufacturing. Although the raw water can vary depending on the location, manufacturers have strict requirements regarding its composition because the beverage must taste the same regardless of the production site. Raw water treatment occurs in several steps during soft drink manufacturing. The first step is to measure the turbidity of the water and feed it to a reverse osmosis system to reduce the concentration of dissolved substances – in other words desalinating the water. This results in taste-neutral treatment of the water, thus ensuring the beverage has a consistent taste.

In reverse osmosis, the natural osmosis process is reversed through a semi-permeable membrane under high pressure. The water penetrates the membrane while other substances are retained. If the raw water is disinfected prior to reverse osmosis, the chlorine must be completely removed, such as through active charcoal filtration, in order to protect the membrane.

The role of chlorine measurement for safe and efficient soft drink production

In many cases disinfection of the raw water occurs downstream from the reverse osmosis process. The disinfection process utilizes 0.3 mg/l of free chlorine, which corresponds to the allowable amount as outlined in the German drinking water regulations. The raw water is then freed of all residual chlorine via filtration since it must be completely free of chlorine before adding the beverage syrup.

However, this filtration is circumvented via a bypass once a week in order to clean the piping with chlorine at low temperatures using a so-called cold cleaning in place (cold CIP) process.

In order to monitor the removal of the chlorine and the cold CIP process, amperometric sensors are installed at two points to measure the amount of free chlorine:

• after filtration to determine if the water is chlorine-free
• in the piping system where the chlorine content must be maintained at 0.3 mg/l.

The special challenge here is the absence of chlorine over a longer period of time after filtration. With many amperometric sensors, this absence leads to a delayed response behavior, with the sensor essentially falling asleep. This can lead to product loss since the beverage syrup is added while undetected chlorine is present in the raw water after filtration. The Memosens CCS51E sensor from Endress+Hauser for measuring free chlorine exhibits no delayed response even after a longer period of inactivity, thus ensuring that any chlorine peaks do not go undetected. The sensor furthermore “notices” chlorinated water once a week when the filtration is bypassed. This tests the functionality of the sensor and ensures electrochemical activation. Compared to wet chemical analyzers that use the DPD method, which can provide a measurement value only every three minutes, inline measurements with amperometric sensors offer continuous measurements in which no peaks are overlooked.

Continuous measurements are furthermore beneficial for controlling the chlorine dosage. The fast measurement value means a more precise dosage: as little as possible, but enough for a reliable disinfection process. Achieving this degree of precision requires creating an adequate flow to the sensor membrane of 15 cm/s. If the sensor is calibrated once a year, the DPD calibration should be carried out by drawing the sample near the sensor, keeping the cuvette clean, observing the expiration date of the DPD reagents and avoiding air bubbles in the sample.

The amperometric sensors require no reagents, making them low maintenance. The new generation of Memosens sensors also stores more data regarding calibration and operating hours – such as the electrolyte counter – and the load, making it possible to develop a more efficient maintenance strategy tailored to the application.

Last but not least, the new generation of sensors is more efficient when it comes to commissioning. Once installed, only a short polarization cycle is required before they begin to display stable measurement values, thus ensuring that the plant is fully functional again within a short period of time.

With some beverage manufacturers, raw water treatment has developed to the point that they have to monitor not only the free chlorine levels but all disinfectant residues. Total chlorine sensors such as the Memosens CCS53E are suitable for these types of measurements. This sensor reliably and quickly monitors free (HC1, OC1) and combined (chloramines) chlorine, thus leading to an even safer product.

Summary

By relying on suitable measurement and dosage technologies that feature fast response behavior, beverage manufacturers can precisely treat their raw water to ensure consistent beverage quality. Reliable and continuous transmission of the measurement data ensures precise dosing of the disinfectant, resulting in increased process efficiency. The Memosens CCS51E and CCS53E sensors from Endress+Hauser meet all of these requirements and also offer connectivity to extended IIoT services through Memosens 2.0 technology for future-proof operation of the plant.

ECD’s HYDRA-DS plug-n-play family of analyzers relies on ISE sensors with digital signal conditioners for the trouble-free measurement of ammonium as nitrogen (NH4+-N) and/or the measurement of nitrate as nitrogen (NO3–N). They feature auto-compensation circuitry for interfering ions and temperature compensation, rugged PVC construction with easily replaceable electrodes and a built-in spray cleaner that minimizes expensive technician maintenance for a lowest total cost of ownership.

Developed for demanding municipal wastewater treatment and water storage applications, the HYDRA-DS Analyzers are ideal for aeration basins, primary or secondary clarifiers, denitrification and final effluent monitoring. For environmental waters, they are useful in water storage applications such as lakes, reservoirs or ponds and to control nutrients from agricultural run-off flows into canals, storage basins and ground water aquifers and wells.

HYDRA-DS Ammonium Analyzers

The HYDRA-DS Ammonium Analyzer is designed to monitor the nutrient load (NH4+) directly in the aeration basin of a wastewater treatment plant. Its powerful sensor uses ISE technology to measure the ammonium, potassium and pH levels. Its self-compensating design automatically compensates for the pH-dependent concentration equilibrium and potassium ion interference on the ammonium electrode.

The ammonium sensor measures the concentration of dissolved ammonium as nitrogen (NH4+-N) in water. The sensor uses three electrodes to determine the NH4+-N concentration, an ammonium ion electrode, a potassium ion electrode and a pH electrode. It is designed for use in all kinds of municipal wastewater or wherever ammonium is present in water.

The ammonium ion electrode performs the primary measurement. Any potassium ion in the sample, however, generates a positive interference in the measurement because of its similar size and charge to the ammonium ion. The HYDRA-DS Analyzer’s highly intelligent transmitter self-compensates by adjusting the signal for this potassium interference and eliminates it from the measurement of ammonium for superior accuracy and reliability.

The ammonium ion electrode measures the ammonium ion (NH4+), not ammonia (NH3). The ammonium ion and ammonia coexist in a pH dependent ratio in solution. The more acidic pH values favor the NH4+ and the more basic values favor dissolved ammonia gas, NH3. The pH electrode measures the pH level, and the transmitter calculates the total NH4+-N concentration based on the pH versus the NH4+ concentration profile stored in the instrument.

HYDRA-DS Nitrate Analyzers

The HYDRA-DS Nitrate Analyzers are designed to monitor the nitrification process directly in a wastewater treatment plant’s aeration basin or clarifier unit. Its advanced sensor uses ISE technology to measure the Nitrate. Also featuring a self-compensating design, the HYDRA DS automatically eliminates Chloride ion interference for high accuracy and reliability.

The HYDRA-DS Nitrate Analyzers measure the concentration of dissolved nitrate as nitrogen (NO3-N) in water. The sensor uses two electrodes to determine the NO3-N concentration, a nitrate ion electrode and a chloride ion electrode. It is designed for use in all kinds of water ranging from municipal and industrial wastewater treatment.

For example, nitrogen typically enters a municipal wastewater treatment plant as ammonia/ammonium compounds. Nitrification oxidizes the toxic ammonium ion into a much less toxic nitrate ion using an aerobic activated sludge process. De-nitrification reduces the nitrate ion (NO3) to nitrogen gas (N2) by an anoxic reaction in the same treatment basin or in a separate anaerobic digester. The NO3-N measurement can optimize the methanol being fed to the digester, minimizing cost, and also provides a trend of the total nitrogen in the effluent.

The nitrate ion electrode performs the primary measurement. A second electrode measures the chloride ions in the sample. The chloride ion, because of its similar size and charge to the nitrate ion, causes a positive interference in the measurement. The chloride ion electrode measures the amount of chloride ion present in the sample and the intelligent transmitter subtracts the appropriate amount of signal from the nitrate measurement.

The HYDRA-DS sensor rapidly measures NO3-N and NH4-N from 0.1 to 14,000 ppm with a response time of 1 minute (T90) and an accuracy of ±3% of reading, dependent on calibration. It operates over a wide temperature range from 32 to 122°F (0 to 50°C). Its highly intelligent transmitter includes an easy-to-read backlit display and comes with two 4-20mA outlets and three SPDT alarm relays. An integral automated sensor spray cleaner reduces biofilms to enhance accuracy and reduce sensor maintenance.
