Gebruder Heyl process photometers and titration instruments have been putting their reliability and practicality to the test since 1958. With improved accuracy and resolution, in combination with analysis functions that have undergone consistent further development, the current generation of instruments helps water treatment system operators reduce costs and guarantee optimal water quality. Improve your water treatment process with online analysis instruments Plant operators and plant technicians can increase the efficiency of the water softening process with constant water quality...

Applications Desalination To prevent corrosion caused by salt, the conductivity of the feed water is controlled by the MultiControl monitoring instrument. The MultiControl monitoring instrument controls the desalination of boiler water with a high salt concentration and regulates the water supply as needed in order to maintain the correct salinity. The desalination electrode is located in the upper region of the steam generator at the height of the lower water level. Our Testomat 2000® checks the hardness of your feed water and condensate water in your hot water boiler and steam...

Precise control attuned to the application can contribute to a significant improvement of the entire production process. Therefore, we made it our mission decades ago to provide our customers with application-oriented solutions in which every individual component is attuned exactly to every other. Monitoring and control of water treatment example: softening plant The following Parameterss must be monitored: • quality • salt deficiency in the brine tank • correct regeneration cycle You can achieve this by using our controllers and measuring instruments in combination: Testomat 2000 ® +...

Recooling plant conceptual solution © Kurita Europe GmbH, Viersen, Germanland Mobile monitoring system for cooling towers with integrated Testomat 2000® Polymer for monitoring the conditioning agent. Control and monitoring of recooling plants legionella. Because of the design, they consequently spread quickly. Today, cooling water controlling and monitoring are indispensable components of advanced energetic and hygiene-compliant operation of cooling towers according to VDI 2047-2 and VDI 3803-3.4. Operators of evaporative cooling systems must therefore still act promptly to avoid...

are very dangerous for humans. Biofilms are also energetically equivalent to mineral deposits such as calcium or silicate deposits. A layer of only 1 mm thickness can cause a loss of efficiency up to 30% with both types of deposits. This, in turn, results in additional energy costs of up to 12%. Conclusion: A controlled cooling tower system monitored online works in a hygienically compliant manner (according to VDI 2047-2), economically and without malfunctions (according to VDI 3803). Many parameters can be measured in the cooling circuit. Our example shows some of them that you can...

Using untreated or partially softened water as the feed water for cooling water circuits or air washers usually causes problems such as: • Limescale, • Biological deposits by myxobacteria and algae (bacterial contamination) • Corrosion of metallic materials. Automatic monitoring and conditioning of the circulating water is important to prevent this from happening. We have developed the automatic desalination device MultiControl CT according to VDI 2047 part 1 and 2 for this application. • Desalination can be controlled either by conductance or by TDS. There is a locking mechanism to stop...

Concept solution for swimming pools The effect of a too low acid capacity on the water treatment facility and water quality is often underestimated. Low acid capacity makes it difficult for the pH value in the swimming pool water to stabilize. The pH value in turn effects the filtration effect and therefore the disinfecting potential. Acid capacity also strongly influences the occurrence of corrosion in parts of the facility that are in contact with water. The water is more aggressive the lower the acid capacity is. This leads to corrosion on metal components such as pump drives and...

When is it necessary to measure phosphate levels? The measurement of the phosphate content in the wastewater of industrial processes becomes more and more important, because the phosphate values must be lower than the legally permitted values if the wastewater is discharged into the sewer system. In accordance with § 11 of the German drinking water ordinance of 2001, the limits are 2,2 mg / l phosphorus (6.75 mg / l PO4) for phosphates added to the drinking water. Where do phosphates come from? Phosphates are mainly found in fertilizers and detergents. They are released into the groundwater...

Chromatography monitoring during the treatment of waste water from electroplating firms During galvanic processes such as copper plating, chromium plating or nickel plating or during surface treatment before painting (phosphating), large amounts of rinsing water are required after each process step. Since the disposal of these process waters is very expensive, it makes sense for a company to process and reuse the process waters. The amount of waste water and fresh water can thus be limited. In many cases, a chemical-physical process is used, e.g. ion exchangers. Regeneration of ion...
