Thioguard® is an effective and environmentally-safe Total System Treatment (TST) for municipal wastewater treatment facilities and sanitary sewers. As municipal-grade magnesium hydroxide slurry, THIOGARD is often described as the “milk of magnesia” for sanitary systems. Providing more alkalinity than any other additive, it is effective at treating odors, corrosion and FOG (fats, oils and grease), and also provides positive plant benefits for nitrification, biosolids production, digester performance, and chlorination.

Thioguard
