What is a chemical feed system?


A chemical feed system in water treatment is a coordinated assembly of equipment designed to precisely introduce treatment chemicals into water streams, whether in storage reservoirs, distribution pipelines, or treatment process channels. Multiple components work together to deliver chemicals to flowing or contained water systems for purposes like disinfection, pH adjustment, coagulation, or corrosion control.
