Precise solutions for water treatment

The wastewater is treated cost-effectively and, at the same time, highly efficiently in accordance with statutory requirements. The key control parameter is the pH value, which is maintained precisely at the target level through the automated dosing of acid or alkali.

Drinking water must meet the highest quality standards and undergo strict controls worldwide. Disinfection and effective water treatment ensure that the water is hygienic and meets high standards in terms of odour, taste and clarity.

Cooling towers dissipate the heat generated during production and therefore require constant monitoring of the cooling water, as this can become a breeding ground for algae and bacteria. Complete control units continuously monitor and regulate parameters such as conductivity, pH and turbidity to prevent biological growth, scaling or corrosion.

In the growing fish farming sector, water quality is monitored around the clock to ensure that factors such as salinity, pH, turbidity and temperature replicate the fish’s natural habitat as closely as possible. High-precision measurement and control technology makes it easy to meet these requirements and can also boost productivity.

Dosing units are required in both large-scale plants and precision dosing systems for small and medium-sized laboratories. Drawing on decades of experience, we develop bespoke, flexible solutions for the continuous or manual dosing of solids, gases and liquids, in both stationary and mobile configurations.

Statutory maximum standards for cleanliness and hygiene require germ-free, hygienically clean water, as well as precise temperature and pH control, for example in the production of cheese or beer. Precise dosing and control technology covers the entire range of applications and ensures that fruit and vegetables remain free from substances that pose a risk to health.

Dosing, measurement and control applications are an integral, albeit often unseen, part of many large-scale industrial plants – from the chemical industry and food production to cleaning facilities and livestock farming. They also ensure reliable operation away from the mainland, for example in shipbuilding, in seaside hotels and leisure facilities, and underground in the mining industry.

Resilient, long-lasting surfaces require corrosion protection, good adhesion for coatings and a flawless finish – and soft, demineralised water is key to achieving this. It improves cleaning results, protects surfaces and water-carrying systems, reduces the use of chemicals and thus boosts efficiency and delivers cost savings.

Different wash programmes each require appropriate dosing and control processes, and the dosing units are exposed to moisture, heat and detergents on a daily basis. Robust dosing pumps are resistant to alkaline soap solutions and provide the precision required to achieve the desired wash result in every programme.

In processes involving large quantities of often expensive chemicals, high-precision dosing is crucial – for example, in electroplating, where spent chemicals must be continuously replenished to maintain a continuous process. Automated, uninterrupted monitoring of chemical concentration via pH or conductivity automatically adjusts the dosing pumps, meaning that manual control is no longer necessary.

To ensure swimming pool water remains in perfect condition, constant monitoring is required to prevent algae growth, bacterial growth and the build-up of contaminants; chlorine-based disinfectants or UV and ozone systems are available for this purpose. UV and ozone systems disinfect without the smell of chlorine, using light or oxidation respectively, whilst the pH and redox values are continuously monitored and regulated to ensure the water remains clean and safe.

Working with oils, fats, lubricants and adhesives requires a high degree of precision, reliability and robustness – power-independent, water-driven proportional dosing units offer the necessary flexibility for this and ensure consistent quality in production. The resulting wastewater is returned to the cycle in a cost-effective and sustainable manner via effective purification systems.

Animal welfare, fertilisation and irrigation require reliable dosing and control technology, whether for clean water and precisely dosed medicines in animal husbandry or for field irrigation during dry periods. Systems tailored to individual requirements ensure compliance with statutory maximum limits for fertilisers, pesticides and insecticides worldwide.

Additives such as brighteners, varnishes and lubricants determine properties such as strength, colour, roughness and coating of the paper grades, which is why precise dosing is essential. Wastewater treatment and the precise dosing of biocides to prevent clumping also reduce cleaning costs and ensure the smooth operation of the machinery.

Effective disinfection of surfaces and contact points is important wherever large numbers of people gather, not just in hospitals, doctors’ surgeries or during a pandemic. Fixed installations ensure continuous disinfection as part of processes, whilst mobile units enable ‘disinfection on the go’.

Professional water treatment is essential in the shipping industry, particularly the treatment of wastewater and the purification of ballast water to protect surrounding ecosystems. Given the limited space available, flexible disinfection systems play a crucial role in this regard.
