Electrochemical Process Enables Sustainable Direct Reuse of California Winery Effluent
Situation
A Sonoma County wine packaging conglomerate, serving 30 of the 50 top US wineries, is in a region of limited rainfall, where canals and reservoirs transport and store water from northern areas of the state. Seasonal variations, population growth, and high transportation costs continue to pressure water users to develop alternative sources for freshwater including seawater desalination, groundwater, and reclaimed wastewater.Read More »Case Study: Winery Effluent
Cutting Edge Treatment Process Paves the Way for Permit Compliance at California Wastewater Treatment Plant
Situation
Discharge permit limitations, governed by the National Pollutant Discharge Elimination System (NPDES) or other local control boards, are often updated to expand protection for downstream ecosystems and users. As a result, a municipal wastewater treatment plant (WWTP) in Southern California was in violation of their Regional Water Quality Control Board’s recently tightened discharge limits. Chloride (Cl-) concentrations now consistently exceeded a maximum threshold of 100.0 milligrams per liter (mg/L) in their secondary effluent.
