This research report is written for engineers who design for the treatment and disposal of water treatment residuals. The book provides engineering, treatment, and disposal data and discussions for all types of water treatment residuals, including those created by coagulant and lime softening, filter backwash water, low-pressure and high-pressure membranes, ion exchange and inorganic adsorption processes, arsenic treatment, radioactive substances, and spent GAC. A chapter also discusses the marketing of water treatment plant residuals for beneficial uses.
