What is Ultrafiltration?

Ultrafiltration (UF) in wastewater treatment is a pressure-driven, membrane-based process (pores 0.01 - 0.1 microns) that removes up to 99.99% of suspended solids, colloidal particles, bacteria, and viruses. It serves as a superior physical, chemical-free barrier for polishing, water reuse, and as pre-treatment for Reverse Osmosis (RO) to reduce fouling.

How UF Works

The ultrafiltration process uses hollow fiber or spiral wound membranes with extremely fine pores that allow only water and dissolved solids to pass through while rejecting larger particles, microorganisms, and suspended matter.

Key Features

  • Membrane Pore Size: 0.01 to 0.1 microns
  • Chemical-Free: No chemicals required for operation
  • High Recovery: 90-95% water recovery rate
  • Automated: Self-cleaning backwash system
  • Compact: Small footprint design
