ROTEC FR-RO to produce UPW for second semiconductor plant in the Philippines, achieving 93% recovery rate

A Japanese multinational corporation that specialises in the development and manufacturing of electronic components will use ROTEC Flow Reversal Reverse Osmosis (FR-RO) technology to produce ultrapure water (UPW) for its semiconductor plant in the Philippines.

The project includes the design, procurement, fabrication, installation, and supply of the FR-RO technology to treat 400m3/day from the customer’s industrial semiconductor plant (Image: ROTEC)

ROTEC will work once again with Acqua Engineering and Technical Services to collaborate on the project. This follows an initial collaboration between the companies on a previous plant in Cebu, the Philippines.

The project presented a number of design challenges: any solution would need to achieve the highest possible recovery, more than 93%, while minimising waste discharge, and meeting ever increasing global sustainability standards.

With these challenges in mind, ROTEC was asked to supply a new UPW system featuring its FR-RO technology that could treat 16.7m3/hr of feedwater.

A two-pass system will be delivered including the use of Electrodeionisation (EDI) to remove ions and ensure lower permeate water conductivity suitable for UPW quality lower than 1μS/cm.

“Working with ROTEC again, I have trust in the technology which has already proved successful in installations across a variety of sectors in APAC and the Philippines,” said Jane Ubalde, owner of Acqua Engineering and Technical Services. “Combining the abilities of Acqua Engineering and Technical Services with ROTEC’s innovation and track record, this project will create a valuable offering for local customers.”
