Abstract

See full text

This specification describes systems for the treatment and reuse of grey water and related processes. An exemplary system collects grey water from baths and showers and treats it for use in toilet flushing. Influent bathing water passes through a prefilter to remove larger particles and flows into a grey water collection tank. Collected grey water is filtered through a membrane designed to remove suspended solids. Membrane permeate passes through a sorbent media to remove soluble organics and then flows into a permeate tank. A chemical agent is used to disinfect water in one or more parts of the system and optionally to clean the membranes. A control system manages the operation of system. The system operates in a generally daily cycle with permeation dispersed over a material time, for example 4 or 8 hours or more.
