pH adjusters and neutralizers

Drinking water plants raise pH to reduce corrosion, coagulation works within a narrow pH window, waste water plants neutralise acidic or alkaline effluent, and power plants and reverse osmosis systems control pH to prevent scaling and corrosion. Magnesium hydroxide slurry is popular for acidic waste water because it buffers and is safer to handle than caustic soda. Carbon dioxide offers a gentle way to lower pH without adding sulfate or chloride.

Ask for concentration or assay, impurities such as mercury in caustic soda and heavy metals in lime, solids content and viscosity for slurries, and drinking water certification. Concentrated acids and alkalis are corrosive dangerous goods that need suitable storage tanks, dosing pumps and personal protective equipment.
