Quincy Water Reuse Utility TDS Control

The paper describes the new Q1W Utility that will integrate its industrial and municipal wastewater treatment systems in Quincy, Washington. At the core of the utility are new membrane ultrafiltration and reverse osmosis treatment systems to control total dissolved solids in the reused water. The ultrafiltration system will be used to meet the Washington standards for production of Class A reclaimed water as well as provide pretreatment for the downstream water softener and reverse osmosis systems. The Q1W will optimize the benefits of water reclamation and reuse using industrial and municipal wastewater and groundwater to create a system of near-zero environmental discharge and a sustainable water supply for the City?s future
