The semiconductor industry relies upon the supply of large volumes of extremely high quality ultrapure water (UPW) to manufacture the cells used in semiconductor systems. Therefore, efficient and reliable water treatment technologies along with solutions to reduce energy and chemical consumption, lower water footprint and recover valuable materials are essential.
Furthermore, semiconductor production processes such as CMP, wet etc., rinsing and background produce a wide variety of effluent streams that each require specific waste water treatment steps.
Depending on the fabrication process, a variety of special treatment processes can also be necessary such as ammonia reduction, denitrification, arsenic removal or recovery of precious metals such as silver.
Ultrapure Water (UPW) generation including pre-treatment, make-up and polishing, advanced waste water treatment for various effluent streams from production processes, Water reclaim & water recycling - reuse technologies and valuable raw material recovery.
