Water is fed directly from the water main through a water meter and back flow preventer.
The cationic polyelectrolyte is normally stored in a 50-gallon supply drum. This drum is transported onto the pump skid with a wheeled trolley and is left on the trolley until it needs changing. The blending pump can be fitted with a variable speed motor drive. This is particularly useful when water flow varies and enables the pump to inject the correct rate of the polyelectrolyte solution in proportion to the varying water flow. System Advantages Saving of an expensive raw material by accurate metering.
