Book Description

Since the implementation of the USEPA Clean Air Act Risk Management Plan, many water treatment and wastewater treatment utilities have converted to on-site sodium hypochlorite generation. Conversion to On-Site Sodium Hypochlorite Generation: Water and Wastewater Applications is a comprehensive text and design manual for on-site sodium hypochlorite generation systems. It covers all issues concerning the design, construction, operation, and maintenance of on-site sodium hypochlorite generation systems and their application for disinfection in water and wastewater treatment facilities.

The text includes a concise discussion of regulatory requirements for chlorination systems and supplies a comprehensive list of equipment and construction materials for both brine and seawater electrolysis systems. Conversion to On-Site Sodium Hypochlorite Generation will provide design engineers, operators, and utility administrators with the working knowledge of on-site sodium hypochlorite generation system design considerations and operational requirements needed to prepare and implement a Risk Management Plan.
