Critical Challenges in Electronics-Grade Water Management
The electronics and semiconductor industry faces unprecedented challenges in water treatment, requiring ultra-pure water systems and advanced solutions for complex fab waste streams.
Extreme Purity Requirements
Ultra-Pure Water (UPW) needs resistivity 18+ megohm-cm and TOC < 1 ppb for photolithography, etching, rinsing and CMP processes.
Complex Wastewater Matrix
Heavy metals (copper, nickel, zinc, chromium, lead, cadmium), strong acids (H₂SO₄, HNO₃), alkalis (NaOH), fluorides, nitrates, organic solvents (IPA, acetone, photoresist chemicals), surfactants, detergents, COD, BOD, TDS, silica, Total Organic Carbon.
Stringent Discharge Norms
Tight limits on metals, organic carbon, fluorides and particulates with zero tolerance for contamination.
Water-Intensive Processes
Thousands of gallons UPW daily; critical process material for nearly every fabrication step in semiconductor manufacturing.
Environmental Mandates
Zero Liquid Discharge and sustainability goals in water-stressed regions with maximum resource recovery requirements.
