Book Description

18 Oct 2002 Wastewater Microbiology
The activated sludge process is the most versatile, commonly used wastewater treatment system in North America; however, many activated sludge processes frequently experience operational problems related to poor compaction or settleability of secondary solids and loss of secondary solids from the clarifier. Eschewing the technical jargon and copious chemical equations found in the majority of wastewater studies, Settleability Problems and Loss of Solids in the Activated Sludge Process speaks directly to plant operators, showing them how to identify and solve common problems and achieve maximum efficiency. Michael 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. Chapters include: Undesired Filamentous Growth Nutrient–Deficient Floc Particles Denitrification Slug Discharge of Soluble cBOD Viscous Bulking or Zoogloeal Growth Production and Accumulation of Foam and Scum Volume II in the series, Settleability Problems will prove to be of unparalleled value to wastewater treatment plant operators as well as students of wastewater microbiology.

Chapters include: ∗ Undesired Filamentous Growth ∗ Nutrient–Deficient Floc Particles ∗ Denitrification ∗ Slug Discharge of Soluble cBOD ∗ Viscous Bulking or Zoogloeal Growth ∗ Production and Accumulation of Foam and Scum The Wastewater Microbiology Series tackles the critical topics of cost–effective operation, permit compliance, process control, and troubleshooting through a microbiological perspective. Volume II in the series, Settleability Problems will prove to be of unparalleled value to wastewater treatment plant operators as well as students of wastewater microbiology.

5.0 out of 5 stars Settleability Problems and Loss of Solids in the Activated Sludge Process 19 Jan 2009
By Amazon Customer - Published on Amazon.com
Format:Paperback|Verified Purchase
This is a great book for troubleshooting settleability problems in activated sludge processes. It is easy to read and understand. It takes all of the best information from the most expensive references, such as MOP-11 by WEF and the "Wastewater Bible" as I call it from Metcalf & Eddy and translates it into material that a plant operator can read in one or two days and be able to make process changes immediately to help solve the problems they are experiencing. Even a most seasoned operator will find this book to be a great reveiw for thoses subtle details that we forget about when our plants are operating well and I highly recommend it for anyone just getting into the wastewater field or anyone interested in how the biological section of wastewater plants work.
