Sodium Hypochlorite Water Treatment Biocide
Sodium hypochlorite (NaOCl) solution is the most widely used oxidizing biocide in water treatment, delivering free available chlorine for disinfection of municipal water, cooling towers, and swimming pools. It rapidly inactivates bacteria, viruses, and protozoa through oxidative cell damage. Supplied as 10–15% available chlorine solution for direct metering pump dosing.

Sodium Molybdate Closed-Loop Corrosion Inhibitor
Sodium molybdate (Na2MoO4) is a non-toxic, chromate-free anodic corrosion inhibitor formulated for closed-loop cooling, heating, and glycol-based water systems where low toxicity is required. It passivates mild steel surfaces through the formation of an iron-molybdate complex film and is favored in food processing, pharmaceutical, and HVAC applications where chromate or nitrite are prohibited.

Sodium Nitrite Corrosion Inhibitor
Sodium nitrite (NaNO2) is an anodic passivator used as a corrosion inhibitor in closed-loop cooling and heating water systems, as well as in diesel engine coolants and cutting fluid formulations. It passivates the iron surface by promoting the formation of a stable iron oxide/nitrite protective layer. Typically used in combination with borax or silicate for enhanced protection.

Sodium Percarbonate (Water Treatment / AOP Grade)
Water-treatment grade Sodium Percarbonate (2Na2CO3·3H2O2) is a stable solid source of hydrogen peroxide and alkalinity, engineered for advanced oxidation processes (AOP), in-situ chemical oxidation (ISCO), pond and lake remediation, and emergency oxygen replenishment in fish farming and wastewater systems. On contact with water it dissociates into Na2CO3 + H2O2, delivering 13-14% active oxygen (27.5% H2O2 equivalent) without the transport hazards of liquid peroxide. Coated grades offer slow-release behavior over 24-72 hours, making it ideal for sediment treatment, dechlorination polishing, and odor control in lift stations. Compared with liquid H2O2, percarbonate is easier to ship, dose, and store at remote treatment sites.

Sodium Persulfate (SPS)
Sodium Persulfate (Na2S2O8) is a powerful, stable oxidizing agent widely used in advanced oxidation processes (AOP) for industrial wastewater treatment and in-situ chemical oxidation (ISCO) for soil and groundwater remediation. When activated by heat, UV light, alkali, or transition metal ions (Fe2+), it generates sulfate radicals (SO4-) with an oxidation potential of 2.6 V, capable of degrading recalcitrant organic pollutants including chlorinated solvents (TCE, PCE), 1,4-dioxane, BTEX, and PFAS precursors. Compared with hydrogen peroxide, sodium persulfate offers longer half-life in the subsurface, higher selectivity, and easier handling as a free-flowing crystalline solid. Also widely used as a polymerization initiator and metal surface treatment etchant.

Sulfuric Acid pH Control Agent (Water Treatment)
Technical grade concentrated sulfuric acid (98%) used for pH depression in water treatment applications including reverse osmosis pre-treatment, cooling water pH control, and wastewater neutralization. It converts bicarbonate alkalinity to CO2 to control scaling potential in high-hardness feed waters and is used to maintain optimal coagulation pH in drinking water treatment.

Zinc Phosphate Corrosion Inhibitor
A blended zinc and orthophosphate corrosion inhibitor formulated for open recirculating cooling water systems. Zinc ions provide cathodic inhibition while phosphate anions form a mixed ferrous phosphate/zinc hydroxide barrier film on metal surfaces. This combination delivers superior mild steel protection at lower total inhibitor concentrations than either component alone.
