Microelectronics

Water treatment solutions to meet the specific requirements of the microelectronics sector :

• Preservation of resources
• Guaranteed supply of process water
• Production of ultrapure water
• Management of utilities and networks
• Treatment of fluorine, ammonia, COD, metals, sludge

• By coupling of ultrafiltration with reverse osmosis
• By electrodeionisation (EDI) for ultrapure water
• By ultrafiltration for treated water of consistent quality
• By a mixed-bed demineralisation process for water of excellent quality (conductivity < 0.1 μS/cm)
• By reverse osmosis to reduce consumption of chemical reagents
• By ion exchange resins to produce soft water of excellent quality, with a reduced quantity of regenerant

• By a physical/chemical finishing process, for the reduction of suspended matter and phosphorus
• By biological processes to eliminate efficiently COD
• By MBR, combining aerobic digestion with separation by ultrafiltration membranes
