J. FREQUENTLY ASKED QUESTIONS (FAQ)
What does the System do?
tested to significantly physically block pathogens including
bacteria, viruses and cysts from your water. The pore size
on the surface of the ultrafilter membrane is 0.02 microns
nominal.
How does the System work?
Filtering - When a household water fixture is turned on,
the water pressure forces unfiltered water into the Prefilter
Housing.
1)
Larger particles (and chlorine when using the Carbon
Prefilter) are removed as the water passes from the
outside of the Prefilter to the inside.
2)
The prefiltered water then passes down into the System
to the membrane chamber.
3)
In the membrane chamber, the water travels through
membrane pores from the outside of the hollow fibre
membrane to the inside, leaving behind unwanted
particles such as bacteria, parasites and certain viruses.
4)
The filtered water then travels through the household
piping, to the household fixture that is being used.
Automatic Cleaning Cycle - The System uses two methods to
clean its membrane: a) flushing and b) draining. The Controller
automatically executes a cleaning sequence consisting of
22
This System has been
a number of flushes and drains to clean the membrane. For
Systems equipped with an Advanced Plus Controller, System
cleaning may be performed multiple times per day, up to 24
times. For choices of cleaning sequences and intervals, refer
to Setting the Controller section under D. OPERATIONS. Water
pressure inside the dwelling will be significantly reduced
during System cleaning.
Flushing - Flushing includes a Front-flush and a Back-flush.
Systems that are installed in municipal, cistern, or ground
water sources may use the flushing method to control the
fouling rate of the membrane.
Front-flush - The Controller opens the Drain Solenoid
Valve. The water supply line pressure causes an inrush
of water into the System, scouring the surfaces of the
membrane and expelling impurities through the drain.
Back-flush - At the same time, the air bladder inside the
Backpulse Tank expands rapidly, pushing clean water
out of the membrane surfaces from the hollow cores.
This action dislodges and pushes out impurities trapped
inside the membrane pores. Impurities are then expelled
out of the System through the drain port.
Draining - Systems that are installed in surface water
sources must use the draining method in addition to the
flushing method to control the fouling rate of the membrane.
During draining, the Controller closes the Inlet Solenoid Valve
and opens the Drain Solenoid Valve, allowing water to be
completely drained out of the System.
Where should the System be installed?
The System is installed inside the home at the point where
water enters the house so that filtered water is provided from
every tap. In order to allow only indoor water to be treated, a
dedicated line should be installed from the inlet of the System
to all external taps for pool or hot tub makeup valves and
irrigation systems. Reducing the volume of water filtered will
assist in prolonging the life of the System membrane. For
Spacing Requirements refer to I. SPECIFICATIONS.
