JDS Uniphase /Lumentum

Tank Certification in 2004 and 2009

In 2003, JDS Uniphase acquired the facility from Readrite, and continued some of the operations generating wastewater. However, the existing treatment system was not designed to process such wastewater. SRI designed and installed a separate transfer system, bypassing the exiting treatment facility, complete with pH monitoring and flow recorder.

San Jose, Ca. Facility – Arsenic and HF removal systems

In 2000 JDS Uniphase acquired Spectra Diode in San Jose, with an existing treatment system installed in an underground vault. By 2004 this system was rusted and creating a possible long term problem. SRI, designed, fabricated and installed an above ground treatment package unit capable of treating the Arsenic and HF wastewater generated from their operation. Chemical Precipitation Technology was utilized to accomplish this treatment. This project was completed within budget and schedule.

San Jose, Ca. Facility – PBR Certification.

SRI has successfully completed multiple Tank Certifications for JDSU, guaranteeing adherence to California Code Regulation Title 22. This essential procedure ensures the secure and environmentally responsible functioning of JDSU’s tank systems. SRI meticulously examined the design, installation, maintenance, and testing protocols of hazardous substance-containing tank systems, taking corrective measures as required. By conducting thorough inspections and ultimately certifying the wastewater treatment systems, SRI effectively averted any potential leaks or spills. JDSU has demonstrated steadfast dedication to environmental preservation through these tank certifications, which are renewed every five years.
