Water Treatment

In cooperation with our partner EWKS Water Technology GmbH, we are able to provide you with appropriate water treatment and water purification for your entire system. EWKS also provides refrigeration systems and components such as cooling machines, cooling towers, system separation and temperature control devices, as well as laboratory analyses, system management, reports and training.

Water Softening

Well water and surface water from the waterworks contain mineral deposits. Water hardness is measured in mol/m³ (°dH). This value can be obtained from your local water works or by analysing your water. Retail, industrial and domestic pipeline networks and equipment that come into contact with hard water must be protected against scale.

Complete water demineralisation

Some of the main factors to consider when choosing process technology include the requirements for the water that you want to produce, the quality of the water available and the operating and investment costs. The reverse osmosis requires neither a regenerating agent (hydrochloric acid and sodium hydroxide) nor a neutralization.

Decarbonisation of water

Water is used in industrial engineering and process technologies. These involve a variety of water quality standards. Most of the minerals dissolved in the water have a disruptive effect and prevent economic operation. Water treatment is absolutely necessary in these cases. One water treatment method is decarbonization using ion exchangers. This treatment method is used for water qualities with middle and high hydrogen carbonate concentrations (carbonate hardness) when there are thermal and mechanical loads involved in the process.
This is the case for cooling water circuits and boilers. Using additional water treatment with decarbonisation for cooling water systems in combination with a downstream water softener for boiler systems means that they can be operated in a cost-effective manner.

Traditional cooling circuits for industrial applications

Regardless of the size of the plant, problems often arise with the quality of cooling water. Impurities (e.g. algae) or the normal contents of water (e.g. calcifiers - the so-called hardness) usually deposit themselves at the warmest point: the tool, the cooling machine or the temperature control unit. This frequently only becomes obvious when the system starts producing waste. These costs and downtime can be avoided by optimizing the water quality! Corrosion causes problems for many operators. Corrosion frequently affects the various metallic materials in the cooling lines and tools - but this can also be handled with very little effort:
