ABSTRACT

Canandaigua Wine Company, Inc. (CWCI) produces a variety of wines and wine products at its Canandaigua, New York winery. Winery wastewaters are treated on-site with an extended aeration treatment system prior to discharge to the City of Canandaigua's Publicly Owned Treatment Works (POTW). This chapter contains a description of the overall selection process, including the pilot plant study, and economic and process comparisons of alternative biological treatment systems for treatment of winery wastewaters. The pilot plant study was conducted with an upflow anaerobic sludge blanket (UASB) reactor followed by an aerobic polishing reactor. The UASB process was selected based on several factors, including the ability to treat high organic loading rates, the successful operation of numerous full-scale UASB systems, reported resistance to upset, and economic considerations. Winery wastewaters were collected daily by a 24-hour composite sampler. System feed comprised winery wastewaters, and UASB reactor effluent and/or tap water.
