LWP CHEMICAL INJECTION/CLEANING MODULE
The chemical injection/cleaning module is a welded aluminum pipe frame that houses a 20-gallon tank T4 used
for batching, mixing, and heating the cleaning solutions for the UF and RO system and to hold fresh product
water. There are three 2.5-gallon tanks for the chemicals that are placed adjacent to the module. One small tank
T5 is used for either sodium bisulfite or coagulant depending on the source water. The second small tank T6 is
used for an antiscalant solution for the RO membranes. The third small tank T7 is used for hypochlorite
dispensing into the product water for disinfectant. There are three chemical injection electronic metering pumps
P5, P6, and P7 that interface with the small chemical tanks. There is a product flow meter and totalizer meter
integrated into the module piping. See Figure 10, Figure 11, and Figure 12.
