Water in the semiconductor industry
Water plays a critical role in electronics production processes, particularly in the manufacture of semiconductors where large volumes of ultra-pure water are required. Semiconductors accounted for 65% of Philips' total water consumption in 2004.
Philips Semiconductors Philippines in Cabuyao Laguna has developed a system to recycle final rinse water used in its polishers.
To do this, the facility operates two systems - one is on standby while the other is in service.
Before this change, water was discharged for wastewater treatment. Now it is recirculated until the system is serviced. This saves on both water and chemicals, as the water is no longer treated.
This project enables the company to save 244 m3 of water per month.
