Everything about water chemistry
Water chemistry for industry and the environment
With a wealth of experience and a range of around 3,000 basic and speciality chemicals, we have all the products on board that are required for effective water chemistry.
We develop and manufacture our own EVC® water treatment products, taking into account the specific requirements of our customers and their water-bearing systems. This enables us to effectively support our customers in meeting and realising their goals in terms of plant safety, efficiency and the environment.

EVC® - EFFICIENT PROCESS CHEMISTRY
The EVC® products we have developed cover a wide range of applications.
Their use enables, for example, improved recycling, compliance with waste water limits or hygienic operation.
This enables companies to optimise their production processes, reduce costs and improve their environmental footprint.

Chlorine dioxide
Chlorine dioxide is highly effective against microorganisms and ensures reliable disinfection. There are hardly any undesirable by-products compared to chlorine and chlorine dioxide is both odourless and tasteless.
Thanks to its high oxidation potential and stability at different pH values, the effect is long-lasting and reliable in a wide range of applications. Chlorine dioxide effectively removes biofilms - for safe and sustainable water treatment.
Use biocidal products with care. Always read the label and product information before use.
Our solution: The 1- and 2-component system
1-component system
- In-situ production of chlorine dioxide from sodium chlorite by oxidation
- High concentration, low dosing quantities required
- Direct application in water
- Effect: bactericidal, fungicidal, algaecidal
2-component system
- Chlorine dioxide produced by mixing two components on site
- Pure chlorine dioxide solution, safe and stable
- Gentle on materials, chlorine-free, individual components can be stored for 5 years
- Complies with DIN EN 12671, TrinkwV, DVGW W224, W557, W291
- Effect: bactericidal, fungicidal, algaecidal, virucidal
Ready-to-use solution
- Ready-to-use 0.29% chlorine dioxide solution
- Can be used immediately, no hazardous goods
- Gentle on materials, chlorine-free
- Complies with DIN EN 12671, TrinkwV, DVGW W224, W557, W291
- Effect: bactericidal, fungicidal, algaecidal, virucidal
