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 without toxic by-products

Kemira KemConnect™ DEX is the ultimate technology for wastewater disinfection. It is based on a mixture of catalyzed formic acid and hydrogen peroxide and when accurately mixed, these two components form highly efficient performic acid solution (DEX-135). Performic acid decomposes to form peroxyl and hydroxyl radicals that kill bacteria and viruses. It takes only a few minutes to disinfect water, and within an hour after dosing the active substance can no longer be detected. DEX-135 breaks down into carbon dioxide and water, leaves no toxic disinfection by-products nor has any adverse impacts on marine biodiversity.

The disinfectant DEX-135 is produced on-site in a standardized mixing unit supplied by Kemira. 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 also provide full operator training and 24/7 remote service.
