What is Water Treatment?

Water treatment is the process of improving water quality to make it suitable for a specific end-use (drinking, irrigation, industrial use, environmental discharge). Treatment processes include physical (filtration, sedimentation), chemical (coagulation, disinfection, pH adjustment), and biological (activated sludge) stages. Drinking water treatment typically includes coagulation, sedimentation, filtration, and chlorination.

Properties & Characteristics

Key processes: coagulation/flocculation (alum, FeCl₃ remove suspended particles), sedimentation, filtration (sand filters, membrane filtration), disinfection (Cl₂, ozone, UV), pH adjustment (lime, CO₂), softening (removing Ca²⁺, Mg²⁺). Wastewater treatment: primary (settling), secondary (biological), tertiary (nutrient removal).

Uses & Applications

Municipal drinking water supply. Industrial cooling water treatment. Pharmaceutical water for injection (WFI). Boiler feed water treatment (prevents scaling/corrosion). Swimming pool sanitation. Wastewater treatment before discharge. Desalination (reverse osmosis).

Safety Information

Treatment chemicals: chlorine (toxic gas), chlorine dioxide (explosive at high conc.), coagulants (alum: irritant), lime (caustic). Overdosing disinfectants creates DBPs (disinfection byproducts) like trihalomethanes — suspected carcinogens. Ozone: powerful oxidizer and lung irritant. Proper chemical dosing control is critical.
