Definition and Applications
Chemical dosing systems inject precise amounts of chemicals into water or wastewater streams. Used for pH control, scaling prevention (antiscalant), disinfection (chlorine, hypochlorite), fluoride removal, coagulation, and other treatments. Essential in industrial, municipal, and power projects.
