Problem Organisms In Water PDF Download

"The drinking water community shares its water systems with a world of microscopic living creatures. Water professionals know that these organisms inhabit, grow, and potentially reproduce in source waters and throughout the treatment plant and distribution system. These creatures may contribute to numerous operational challenges, from problems in source water through finished water, including encrustation or corrosion within the water system and water quality problems at the customer's tap. This organism diversity makes it difficult for water treatment operators and water quality managers to be familiar with every organism. When problems arise, there is often no place for an operator and water quality manager to turn for help. To address this gap, this manual provides information regarding nuisance organisms, the problems they cause, treatment options, and references to literature resources. This fourth edition includes two new chapters, Free-Living Protozoa and Invasive Aquatic Plant Species, and a new Taxonomy Overview. The fourth edition provides more robust information to operators and water quality managers by incorporating current taxonomic structure based on molecular studies, updated information on the significance to water supplies and control strategies, expanded references for each chapter, a new detailed glossary, and a user-friendly troubleshooting guide"--
