Alta Devices, a solar cell manufacturing facility in Sunnyvale, California, partnered with SRI for numerous projects from 2013 until its closure in 2021. SRI designed, permitted, and installed a comprehensive wastewater treatment system for Alta Devices, which included drain lines, equalization tanks, pump stations, microfiltration systems, chemical distribution, and a filter press. The system was designed and fabricated for future expansion and recycling the wastewater back to their operation. SRI has also certified the tank system under the PBR framework after successful installation and startup of the system. SRI continued its relationship with Alta Devices, providing ongoing maintenance and support until the facility’s closure, supervised by the Sunnyvale Fire Department.
