pH adjusters are chemicals used to control the acidity or alkalinity of water in treatment processes. Common acidic adjusters like sulfuric acid and hydrochloric acid lower pH, while alkaline agents such as sodium hydroxide (caustic soda) and lime (calcium hydroxide) raise pH. Maintaining optimal pH (typically 6.5–8.5) ensures effective disinfection, corrosion control, and coagulation in drinking water, wastewater, and industrial systems. Proper pH balance also enhances chemical efficiency and protects infrastructure.

Sodium Dihydrogen Phosphate

Sodium Dihydrogen Phosphate (NaH₂PO₄) is a white crystalline powder or granule, highly soluble in water. It is widely used as a buffering agent, emulsifier, and pH adjuster in various industrial, food, pharmaceutical, and laboratory applications. It acts as a source of phosphate ions and helps maintain the stability and consistency of formulations. This chemical is commonly utilized in food processing, water treatment, detergents, and as a reagent in chemical synthesis.
