Abstract
A domestic water recycling system using a combination of an optical detector to detect certain smaller sized (non-filtered) contaminants and a filter to remove larger sized (filtered) contaminants provides an efficient wastewater recycling system. Optical detection of contaminants determines whether water is discharged or filtered and recycled. The optical detection system can use several discrete optical wavelengths that are passed through the fluid, and can determine a relative presence of the contaminants based on the resulting wavelength response. A recycling shower using optical detection, an electronically actuated directional device and pump and a controller allows for automatic recycling or discharging of water without requiring user input. The system may include a turbulence reduction baffle in a collection chamber, and a disinfection unit for the recycled water.
