Applications
The HYDRAcap60 Ultrafiltration Membrane is specifically engineered for environments where ultra-low particulate levels are essential. Its high surface area and reliable barrier performance make it particularly suitable for:
Semiconductor water treatment systems – as a pre-treatment step to reverse osmosis (RO) in UPW plants
Flat panel display (FPD) fabrication processes – removing submicron particles and colloids
Photovoltaic cell manufacturing – ensuring particle-free water for sensitive rinsing and etching stages
Precision optics and microelectronic facilities – where water purity directly affects product integrity
Electronics-grade resin regeneration protection – preventing foulants from reaching ion exchange beds
Laboratory and cleanroom water loops – for polishing loop filtration or point-of-use security filtration
The membrane’s robust structure ensures operational stability, even during long filtration cycles or challenging feed conditions, reducing downtime and maintenance frequency.
