Project Briefs:

Semiconductor Manufacturing Facility Gets HERO™ Upgrade

Project Overview

In San Jose, California, new water usage regulations mandated that a local, high-profile semiconductor manufacturing facility decrease both their water consumption and waste. The client upgraded their existing system, improving their water quality and saving thousands of gallons of water despite an extremely tight time frame and space constraints.


Improve the client’s water recovery and quality while increasing production volume and meeting local water usage regulations.

Scope of Service

The client worked with SAMCO to develop an effective solution that comprised a feasibility study, system component fabrication, field installation, controls integration, and startup.


  • High water conductivity
  • Extremely tight footprint
  • Critical uptime to maintain client’s production schedule


Expanding upon the client’s existing double-pass reverse osmosis (RO) system with a High-Efficiency Reverse Osmosis (HERO™ ) system, SAMCO helped the client increase their water recovery from 65% to 95%. In collaboration with the standard RO process, a high-purity DI polishing treatment yielded superior improvement in ionic purity and organic removal, allowing for higher production capacity and less wastewater—saving the client over 28,000 gallons of water per day and winning the client an award from the local municipality for savings realized.


Project deliverables and equipment included:

  • 8” Diameter RO system upgrade to HERO™
  • Electrical/Instrumentation modifications
  • Addition of chemical feed and control systems
