Precoat filtration is a US Environmental Protection Agency- (USEPA-) accepted filtration technique for potable water treatment. When the Surface Water Treatment Rule (SWTR) went into effect in 1989, it provoked a renewed interest in this filtration process as well as other accepted filtration methods. This manual provides general guidelines for the use of precoat filtration, commonly called diatomaceous earth (DE or diatomite) filtration, in potable water treatment. It includes an evaluation of appropriate applications for precoat filtration, discusses the design of economical filtration...

This operations manual provides information for water treatment operators about waterborne viral, bacterial, and parasitic pathogens. It describes each type of pathogen, how it enters the water supply, its diseases, and its treatment.

The manual provides operational procedures for monitoring, sampling, and testing; treatment and disinfection practices for all types of pathogens; and control techniques, including cross-connection control, dead-end flushing, and hydrant flushing. Includes waterborne disease statistics.

Reverse osmosis (RO) and nanofiltration (NF) are membrane technologies that can be applied to the treatment of various water sources for the production of drinking water. This newly revised manual brings you the most current information about RO and NF from theory, applications, and design to equipment, installation, operation, and maintenance.

The manual provides a thorough overview of RO and NF technologies. Chapter topics encompass theory and applications, design, equipment, installation, operations, and maintenance. Includes tables, figures, appendixes, references, and glossary....
