Electronics & semiconductors industry
This industry involves wafer fabrication, etching, plating, doping, and packaging, using ultrapure water and precise chemicals. Wastewater is generated from rinsing, chemical etching, and equipment cleaning, while air emissions occur from acid baths, fume hoods, and wet benches.
Effluents contain COD up to 5,000 mg/L, TDS exceeding 15,000 mg/L, fluoride, ammonia, heavy metals (copper, lead, arsenic), and residual solvents. pH varies widely due to acids and alkalis. Air pollutants include acid fumes (HF, HCl), solvent vapors, and particulate matter.
Treatment starts with neutralization tanks, followed by electrocoagulation and heavy metal precipitation, then ultrafiltration or reverse osmosis for polishing. Air treatment includes wet acid gas scrubbers, activated carbon beds, and HEPA filtration systems for cleanroom exhaust.
