Water Recycling Technology
Google, Inc., Mountain View, CA

Google Inc. retained West Yost to manage a testing protocol to establish the “proof of concept” for treatment technology to treat onsite wastewater for beneficial use at a building location. The proposed technology was developed by NASA for use in outer space explorations. It consisted of a dual membrane process incorporating forward osmosis and followed by reverse process. A six-month testing program was performed at the Codiga Research Center on the Stanford campus. Performance testing was conducted on real graywater and blackwater wastewater streams. West Yost managed the testing effort in partnership with researchers at Stanford. West Yost presented the findings and conclusions that proved that the treatment concepts would meet recycled water quality standards for use at building locations.
