Nelsen Poly UF™ System

The Nelsen Poly-UF™ system offers filtration down to 0.02 micron at service flow rates up to 12gpm. Utilizing ENPRESS'
patented and industry exclusive liner design, the internal UF module treats colloids, bacteria, cysts, viruses, turbidity, tannins, and other particles down to 0.02 micron size.

MEMBRANE: The patented polysulfonebased Outside/In Ultrafiltration Membrane is designed for turbidity, cyst reduction and fine sediment filtration applications, and is NSF 61 certified. The membrane operates with flow from the outside-to-inside.

Benefits include minimized risk of deep clogging, simple cleaning with water and/or air, and a compact design. The membrane is non-biodegradable, and has superior mechanical and chemical resistance. The high surface area UF bundles require normal line pressure to operate, low waste discharge when in backwash/ cleaning mode, and offer low pressure drop with high service flow rates.

The Nelsen Poly-UF™ can be utilized as a final polishing stage or on water reclamation systems for rainwater or Grey water, along with offering protection during power outages and intermittent power. The system is BioVir certified and tested for log reduction.

The Nelsen Poly UF System features the Polymeric Ultrafiltration (Poly-UF) Vessel system and the "C-Series" backwash control valve for daily backwashing of the membranes. The vessel also comes standard with a bottom drain opening and ball valve for ease of drainage and cleaning purposes of the tank system.

Nelsen Scale Prevention SystemsNelsen Scale Prevention System Residential Line

Available in 5 Residential sizes, 8", 9", 10", 12" & 13", Nelsen Scale Prevention System features Filtersorb SP filter media to first remove the already existing scale from pipes and heat exchanger surfaces (descaling effect) and further to protect the system from future formation of scale (scale protection effect).

Filtersorb SP is based on a completely new technology. In this process the chemical structure of scale forming minerals is changed. This technology is so effective that it requires a contact time of only seconds.
