Reihe: Wastewater Microbiology

A practical guide to wastewater bacteria and the roles they performin wastewater treatment
Communicating material in a practical manner for operators andtechnicians who regulate and troubleshoot their wastewatertreatment processes, Wastewater Bacteria discusses the effectivecontrol and proper operation of aerobic (activated sludge) andanaerobic (anaerobic digesters) biological treatment units toensure that an adequate, active, and appropriate population ofbacteria is present in each treatment unit. It is a hands-on guideto understanding the biology and biological conditions that occurat each treatment unit.
Avoiding unnecessary technical jargon and chemical equations,Wastewater Bacteria, the fifth book in the Wastewater MicrobiologySeries, explores and explains:
* Bacteria and the wastewater environment
* Enzymes and sludge production
* Nitrogen, phosphorus, and sulfur bacteria
* Floc formation and filamentous organisms
* Nitrification and denitrification
* Sulfate reduction, fermentation, and methane production
* Toxicity
* Foam and malodor production
The goal of Wastewater Bacteria is to enable plant operators toachieve the twofold basic objectives of wastewater treatment-todegrade organic wastes to a level where a significant, dissolvedoxygen demand is not exerted upon receiving waters and to removenutrients to levels where photosynthetic organisms in receivingwaters are limited in their growth. This straightforward manualequips plant technicians to meet these objectives with essentialinformation to understand the biological processes and organismsinvolved in wastewater treatment.
