WATER INTEGRITY IN TREATMENT AND DISTRIBUTION SYSTEMS

摘要

As a measure of water integrity in water treatment and distribution systems, stabilized hydrogen peroxide is used as the secondary disinfectant. The concentration of hydrogen peroxide is monitored throughout the system and, if needed, additional hydrogen peroxide is injected into the system to maintain the level at established standards.

主权项

1. A water treatment and distribution system comprising:
a. a primary disinfectant apparatus for disinfecting source water; b. a first dosing apparatus to inject stabilized hydrogen peroxide into the system; c. a first monitoring apparatus to measure the concentration of hydrogen peroxide residual; d. one or more further monitoring apparatus to measure the concentration of hydrogen peroxide residual downstream of the first monitoring apparatus; e. one or more further dosing apparatus proximate the one or more further monitoring apparatus, each capable of injecting stabilized hydrogen peroxide into the system; and f. a network of pipes connecting the source water to the primary disinfectant apparatus, the primary disinfectant apparatus to the first dosing apparatus, the first dosing apparatus to the first monitoring apparatus, the first monitoring apparatus to the one or more further monitoring apparatus and the one or more further monitoring apparatus to the one or more further dosing apparatus.
