This operations manual describes nonpathogenic organisms in source water, the various problems they can cause in water treatment, and treatment strategies.
Ninety percent of water systems must deal with tastes, colors, or odors at customer taps, intake clogging, and water main corrosion, all caused by nuisance organisms in the water supply. This AWWA Manual of Water Supply Practices provides solution to these problems. The manual identifies most of the problem organisms found in water supplies and provides recommendations for removing or inactivating them. Chapters describe and illustrate each organism, explain the types of problems it can cause, and offers suggestions for treatment or control. Nonpathogenic organisms covered include actinomycetes, iron bacteria, sulfur bacteria, nitrifying bacteria, nematodes, bloodworms or midges, crustacea, rotifers, zebra mussels, algae, and protozoa.
The manual includes a Troubleshooting Guide for Problem Organisms and color plates that illustrate the organisms.
