Stainless Steel Ultrafiltration
- Porous stainless-steel tubular membranes (5/8” ID) with internal titanium dioxide coating (0.02 micron average pore size)
- Welded and bolted construction in ASME code-stamped pressure vessel; 5′, 10’ and 20’ lengths available in any diameter
- Membranes last 10+ years in challenging applications with little downtime, maintenance, or repair
- Simple, robust system with no internal moving parts and efficient externally mounted pump
- Flexible and tunable: Can operate in batch-mode or continuously and be mounted horizontally or vertically
- Minimal pre-filtration required
- Proudly manufactured in the USA

Polymeric Ultrafiltration (pUF)
- Our pUF consists of a unique PVDF membrane chemistry, energy-saving module design, and patented closed-loop operating protocol for achieving high permeate recoveries.
- Our pUF performs in high strength, high solids wastewater treatment or thickening applications, providing UF quality effluent (0.04 micron pore size) with minimal energy consumption.
- Our pUF is the world’s only outside-in crossflow UF membrane filtration technology for high strength and high solids wastewater.
Our Parallel Channel PVDF Module
- Outside-in permeation occurs in parallel channels
- The required crossflow velocity to achieve high flux rates is 2-10x less than tubular membranes, resulting in dramatic energy savings
- High membrane packing density (385 ft2 in a 10” x 10’ module)
- Up to 20 psi backwashing capability to maintain peak performance
- Systems are designed to run continuously in a feed and bleed configuration or with internal concentrate thickening in a repeat batch configuration
- Typical electrical consumption: 2.5-3.0 kwh/1,000 gal of permeate
