Sulfur dioxide (SO2) provides an instantaneous, stoichiometric chemical reduction that converts toxic free chlorine and chloramines into harmless, bio-inert chloride and sulfate ions without altering water clarity.\n\nIndus supplies certified technical-grade liquid sulfur dioxide (minimum 99.9% purity) contained under vapor pressure inside seamless or longitudinal-welded forged carbon steel ton containers. Each 907kg container is fabricated in strict compliance with DOT-106A500X / ASME Section VIII and ISO specifications, equipped with dual forged brass valves (one for vapor withdrawal and one for liquid dip-tube withdrawal) and three fusible safety pressure relief plugs rated to melt safely at +71°C in emergency fire events.\n\nBecause sulfur dioxide reacts instantly on a 1:1 chemical equivalent basis with free chlorine (0.9 to 1.1 parts SO2 per 1 part Cl2), treatment plant engineers can achieve precise residual control using standard vacuum sulfonator feed systems paired with downstream oxidation-reduction potential (ORP) probes.
