Disinfection

Keeping Pathogens in Check

The Secondary Treatment effluents conveyed to the disinfection channel are chlorinated with Sodium Hypochlorite (NaOCL) which is a concentrated ‘bleach’. This destroys most pathogens, or disease-causing bacteria. The effluent is then de-chlorinated before it is released through an outfall pipe and diffused into the receiving water body, Sinclair Inlet, Puget Sound.
