Kemira’s DesinFix is a complete solution including chemicals, equipment, and related services, and has been developed to meet disinfection needs related to the reuse of water in applications such as irrigation, recreational use, and industry.
DesinFix contains a highly efficient mixture of formic acid and hydrogen peroxide. Mixed together, these create a highly efficient biocide, DEX-135. The latter forms hydroxyl radicals, which kill bacteria. Measurements have shown that up to a 6 log (99.9999%) kill ratio can be achieved using a DesinFix solution.
DEX-135 takes only 10 minutes to disinfect water, and can no longer be detected an hour after dosing, as it breaks down into CO2 and water, releasing no toxic by-products.
Kemira has R&D centres in Finland, China, the US, and Brazil, and employs some 450 people in research. Other recent R&D success stories in addition to DesinFix® include H2S-Guard™ for dealing with odour and corrosion problems related to hydrogen sulphide; LumiKem®, a monitoring process that helps paper mills optimise their wastewater treatment; FennoClean D, for controlling biofilm oxidising biocides; and KemGuard® polymers.
DesinFix also offers low energy consumption, competitive operating costs, minimal maintenance requirements, and a much lower investment cost compared to UV-light or ozone disinfection.
