It examines both basic theory as well as the latest advancements in practical applications, including nutrient removal and recovery, methanogenesis, suspended growth bioreactors, and more. The information is presented in a very user-friendly manner; it is not assumed that readers are already experts in the field. It also offers a brief history of how microbiology relates to sanitary practice, and examines the lessons learned from the great epidemics of the past. Numerous worked example problems are presented in every chapter. 606 $aMicrobial ecology 615 0$aMicrobial ecology. 676 $a579.17 700 $aHaug$b Roger Tim$0151180 801 0$bOCoLC-P 801 1$bOCoLC-P 906 $aBOOK 912 $a9910956766403321 996 $aLessons in Environmental Microbiology$94491170 997 $aUNINA
