Several water and wastewater treatment process require a chemical feed and metering system for numerous applications such as flocculation, coagulation, disinfection and alkalinization. These chemicals can be in a gaseous, liquid or dry state. The chemical feed and metering systems should be designed according to the state and type of chemical. The following chart briefly presents the basic equipment for gas, dry and liquid chemical feed:

All metering pumps and valves should be carefully selected. Moreover, a good piping selection and design is critical in order to avoid corrosion problems and/or leakage. With over 3000 projects executed worldwide, let Napier-Reid be your single solution for water and wastewater treatment.
