Biocides and disinfection

Biocide is a chemical or physical agent that prevents the biological deterioration of materials and has a controlling effect on harmful organisms. Biocides are used e.g. for disinfection, preservation, sterilization, sanitization and microbial control.

The Kemira biocides and disinfection chemicals come with extensive regulatory and application expertise. The Kemira AMA biocides can be used in e.g. air washer systems, industrial scrubbing, recirculating cooling water, heat exchangers, industrial wastewater systems, biodigesters, RO membranes and for for clay slurries, adhesives and construction materials. The Kemira KemConnect® DEX is a chlorine-free disinfection system based on performic acid (PFA) that can be used to treat all kinds of water, from raw water and industrial and municipal wastewater, to storm water overflows.

Kemira KemConnect® DEX: efficient, rapid and safe disinfection

Kemira KemConnect® DEX is the ultimate technology for wastewater disinfection. The solution is based on performic acid. It is halogen-free, so it does not form the halogenated disinfection by-products — such as trihalomethanes and AOX — associated with chlorine-based disinfection. Performic acid is generated on site as an equilibrium mixture and decomposes rapidly. Residual performic acid, formic acid and hydrogen peroxide are present at levels depending on dose, contact time and water matrix, and can be monitored using established analytical methods.

A typical installation consists of two storage tanks for the chemicals, two transfer pumps and a fully automated mixing unit. All come with minimal maintenance requirements. KemConnect DEX technology includes all the required chemicals and equipment necessary to feed the chemicals, as well as handling of all installation and commissioning services, backed up by maintenance and technical support. To ensure efficient and safe operation we provide full operator training.

Would you swim in Paris’ Seine river? We would! And here’s why: 
Big cities like Paris can get extremely hot during summer. When concrete structures heat up, summer in the city can get awfully exhausting, and citizens are craving for a swim. After 102 years, Paris has re-opened the Seine river for public swimming. Award-winning technology is a key enabler.
