Wastewater Treatment for a Semiconductor Manufacturer (Israel)

About

IDE provided a comprehensive solution to a large semiconductor manufacturer that needed to treat its fab’s industrial wastewater in order to maximize water reuse, minimize environmental impact, and meet local regulations. 

IDE installed its MAXH2O® Pulse Flow RO (PFRO) system to treat cooling tower blowdown (MBR effluent) together with a variable, concentrated CMP stream. The PFRO system was deployed alongside a legacy RO unit that struggled with high fouling and unstable feedwater conditions. Today the system treats ~720 GPM (~4,000 m³/day) and achieves 54% recovery (silica-limited), with an expected increase to 88% as operating conditions and constraints are optimized

  • Capacity: 2000 m³/day
  • Water Source: CTBD after MBR treatment & Concentrated CMP stream
  • Technology : Pulse Flow RO (PFRO)
  • Contract Type: Engineering, Procurement, supply, supervision of erection, startup & commissioning
  • Location : Israel
  • Customer : Industrial
  • Usage : Industrial use/Reuse as cooling water.
  • Commissioning : Jan 2022

Highlights

  • High recovery

    Recovery of additional 54% from the upstream treatment system brine, resulting with an overall recovery  rate of 88%.

  • Technological leadership

    IDE’s proprietary patented single-stage PFRO technology overcomes the challenges of conventional RO operation by discharging brine in a pulse flow regime through short, high-velocity surges.

  • Low maintenance requirements

    System configuration simplifies the preventive maintenance approach by utilizing IDE’s smart CIO (Clean In Operation) with short and frequent cleanings during the system operation , which increases the time between CIPs and the overall system availability
