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
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.
LIGHT COMMERCIAL SYSTEM
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 Systems
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.
