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. The challenge was severe and highly variable feedwater conditions, including a high fouling tendency, SDI values most of the time above 5 (and at times non-measurable), and significant variation in feedwater composition (both TDS and organic matter), which caused a pre-existing conventional RO to struggle to the point that it could not operate reliably, even with weekly CIP.
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 the legacy RO unit, stabilizing overall operation under challenging, variable 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.

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
