Product Description

Rosun Disinfectant Powder is an advanced oxidationtechnology basing on sulfate radical [SO4-], using potassium monopersulfate compound powder(2KHSO5.KHSO4.K2SO4)as its active ingredient, by using high-energy activation technology to produce active oxygen [O] through the chain reaction after being dissolved in water, and to produce different kinds of high effective redox potentials, such as small molecule free radicals with high-energy and high-activity, new ecological oxygen atom, hydroxyl radical [.OH], sulphateradical [SO4-.] thus to become a high-effective disinfectant.DW-1.jpg.jpgPRODUCT FEATURE


Powder form, stable under normal temperature, easy to transport, storage and application, not belongs to explosive or poisonous product, period of validity is two years.

The product main active ingredient is active free radical, will not produce much harmful by-products, will not cause environmentpollution.


1. Continuously produce a large amount of active ingredients

When product dissolved in water, through cycle chain reaction, it will continuously produce Active Oxygen (O), Sulfate free radical[SO4- ],hydroxyl free radical [ .OH ] which have strong oxidizing property,synergetic sterilization.

2. Active ingredients with high oxidation potentiaI

It can remove alga, oxidize and degrade the organic matter, pesticide residue,heavy metal,etc.

3.Persistent sterilization

The content of active oxygen in the disinfectant solution gradually decreases with time, and only decays by 50% after 84 hours and the sterilization effect is long.
