Eschewing the technical jargon and copious chemical equations found in the majority of wastewater studies, \u003ci\u003e\u003cb\u003eSettleability Problems and Loss of Solids in the Activated Sludge Process\u003c\/b\u003e\u003c\/i\u003e speaks directly to plant operators, showing them how to identify and solve common problems and achieve maximum efficiency.  \u003cp\u003eMichael H. Gerardi’s hands-on guide addresses the most common plant operational problems, such as increased costs, loss of treatment efficiency, and permit violations. Using numerous tables and illustrations, Settleability Problems provides microscopic and analytical techniques for troubleshooting and identifying the conditions responsible for settleability problems and loss of solids. It includes pictures of wet mounts and smears of acceptable and unacceptable microscopic conditions of the activated sludge and presents corrective measures for operational problems.
