USP-OC31 Chlorite Oxidant

USP-OC31 Chlorite Oxidant

USP-OC31 is a chlorite based oxidant blend that effectively and rapidly oxidizes hydrogen sulfide and organic odors in wastewater collection systems and treatment plants including headworks, thickeners and dewatering operations. USP-OC31 is environmentally-friendly and does not form chlorinated by-products, with the end-product being table salt (sodium chloride).

USP-OC31’s main active ingredient, sodium chlorite (NaClO2), is a fast-reacting oxidant (seconds) that provides immediate control of hydrogen sulfide and many organic odors in both collection systems and treatment plants, particularly in solids processing operations.

Unlike hypochlorite, USP-OC31 does not react with ammonia and does not form chlorinated organics. USP-OC31 oxidizes hydrogen sulfide according to the following equation:

Neutral-Acid pH: 2 H2S + NaClO2→ 2S + HCl + NaOH + H2O

Alkaline pH: S2- + 2 NaClO2→ SO42- + 2 NaCl

Theoretical dose ratios of USP-OC31 are dependent on the pH of the solution being treated. Under neutral-acid pH, the theoretical dose ratio is 1.4 lbs NaClO2 per 1 lb H2S, with practical dose rates anywhere from 1.6 to 4 depending on the application. Under alkaline pH conditions, the theoretical dose ratio is 5.6 lbs NaClO2 per 1 lb H2S with practical dose rates anywhere from 6 to 12 lbs per lb H2S depending on the application.
