Flows can vary by 90%. The flexibility integrated into the design has allowed the operators to maintain effluent quality.
DESCRIPTION
The Washington State Fire Training Academy (FTA) is owned and operated by the Washington State Patrol. The FTA project demonstrates that small remote wastewater treatment facilities are practical to reclaim water for various uses with current technology. Simple “packaged” equipment designed on skids reduces capital costs because these units are fully assembled and tested at the factory before shipment to the construction site. Continuous reading and recording of key operating parameters, including trans‐membrane pressure, effluent turbidity, ultraviolet (UV) light disinfection intensity and chlorine residual, allow for remote operation using a laptop computer from anywhere with Internet access.
