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.
