“…Full-scale anaerobic co-digestion with municipal wastewater sludges was shown to be effective for the treatment of a wide variety of wastewaters from the food industry, including fats, oils, and greases (FOG); dairy manufacturing wastewater; slaughterhouse wastewater; and winery wastewater (WWW), among others [ 3 , 4 , 5 , 6 , 7 , 8 ]. Wastewaters generated by the food industry are often also biodegradable by aerobic biomass, and co-treatment with domestic wastewater in the aerobic bioreactors at municipal WWTPs was also successfully used for co-treatment [ 9 , 10 ].…”

High-strength wastewaters from a variety of sources, including the food industry, domestic septage, and landfill leachate, are often hauled to municipal wastewater treatment plants (WWTPs) for co-treatment. Due to their high organic loadings, these wastewaters can cause process upsets in both a WWTP’s liquid and solids treatment trains and consume organic treatment capacity, leaving less capacity available to service customers in the catchment area. A novel pre-treatment method, the Waste Activated Sludge-High Rate (WASHR) process, is proposed to optimize the co-treatment of high-strength wastewaters. The WASHR process combines the contact stabilization and sequencing batch reactor processes. It utilizes waste activated sludge from a municipal WWTP as its biomass source, allowing for a rapid start-up. Bench-scale treatment trials of winery wastewater confirm the WASHR process can reduce loadings on the downstream WWTP’s liquid and solids treatment trains. A case study approach is used to confirm the economic viability and environmental sustainability of the WASHR process compared to direct co-treatment, using life-cycle cost analyses and greenhouse gas emissions estimates.
