Water scarcity and source water contamination concerns are fueling ever-increasing interest in the practice of direct potable reuse (DPR) systems. DPR uses many of the same wastewater and drinking water treatment systems currently in place, but instead of putting the treated wastewater back into the ground, the water is stored to be withdrawn as needed by the water treatment plant (WTP).

Accurate and repeatable chemical dosing is essential for successful water treatment, as even minor deviations can lead to severe consequences including regulatory violations, infrastructure damage, and treatment failure. The good news is, with most metering pumps and related equipment a few simple steps taken during initial installation and throughout their usage lifetime, can ensure the reliability and consistency of chemical dosing systems.

The pH level of water plays a significant role in every stage of a municipal water treatment system, including disinfection, filtration, and corrosion control. Proper pH management is essential for optimizing treatment processes, and maintaining pH levels is crucial in drinking water treatment to ensure the safety and quality of the water supply. CO2 is an environmentally friendly treatment method that can have long-term cost benefits.

This Midwestern plant treats influent flow which is largely domestic, with some percentage being industrial. The plant was experiencing good results using peristaltic metering pumps, the issue the WRF faced was the equipment room was cramped and the piping cumbersome. They turned to a firm specializing in municipal and industrial water and wastewater treatment to assist in streamlining the equipment room.
