Filtration Equipment
Nelsen Poly UF System
The Nelsen Poly-UF™ 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 polysulfone-based 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, with benefits of minimized risk of
deep clogging, simple cleaning of the membrane surface
with water and/or air, and a high area volume ratio that
allows for 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.
