The book offers a “natural” perspective, focusing on simplistic, reliable, and practical measures that professionals can use to quickly identify and correct operational problems in activated sludge processes (ASPs). \u003c\/p\u003e\n\u003cp\u003eGerardi covers the biochemical fundamentals of the ASP and in-plant techniques that enable operators to monitor and correct daily changes in operational conditions, sewer systems, and industrial discharges.
