Pure water treatment is the process of removing undesirable chemicals, biological contaminants, suspended solids and gases from raw water. Water treatment by chemical precipitation is a complex process. It starts with adding flocculants, specifically, Polyaluminium Chloride (PACl) and Sodium Hydroxide (NaOH) into raw water.
Vaisala K-PATENTS® Teflon Body Refractometer PR-23-M provides in-line measurements of Polyaluminium Chloride and Sodium Hydroxide at the initial stage of the purification process, ensuring the efficient flocculation of undesired particles. By measuring Sodium Hypochlorite and Fluoride at the water disinfection stage a high-quality purified water at the outlet is assured.
