The PENTEK® Freshpoint™ Ultrafiltration System
provides complete point-of-entry (POE) filtration proven
to reduce turbidity, particulates and cysts for safer, cleaner
water at every tap. The system employs hollow-fiber Ultrafiltration
membrane technology to filter impurities as small as 0.025
microns.
To maximize membrane capacity and service life, a metered
flushing cycle is controlled using an advanced controller
and high-performance turbine meter. The self-cleaning forward
and back-flush cycles are initiated when the programmed
capacity of the membrane is reached. During the backwash,
flow is reversed and particles are ejected from the pores
of the membrane and flushed to drain. In the forward- flush
cycle, service water passes through the capillaries at a
high speed, scouring particles from the membrane surface
and rinsing them from the system. Since power is only required
to flush the system, outages and interruptions will not
jeopardize the integrity of membrane or its ability to provide
safer, cleaner water.
The advanced electronic controller provides a programmable
day override which allows the unit to flush every day with
fresh water when the system is not in use. Critical system
diagnostics, including totalized flow, instantaneous flow
rate, and previous days water usage, are available to optimize
flushing cycles and monitor performance.
The high-performance industrial fiberglass housing is pressure
rated to 300 psi. Inside the housing, the membrane is sealed
with double radial o-rings, minimizing the potential for
leak paths. Quick-connect end caps allow the membrane to
easily be removed for cleaning or replacement.
The system can be applied to solve “known” water
problems including high turbidity, suspended solids, and
certain microbiological contaminants. It can also serve
as a flushable prefilter to extend the life of media filters
downstream. |
