Self Cleaning Irrigation Filter Horizontal Installation For Water Treatment

PRODUCT DESCRIPTION
Sealing Water Automatic Self Cleaning Filter, Exchanging Water Filtration​



Description


GFK series automatic self-cleaning filter is the particularly designed high
performance filter by LIVIC for the water fine filtration. The automatic self-
cleaning filter can efficiently remove the suspended solids, sediment and
planktons from the water. The automatic self-cleaning filter cleans and
regenerates the filter screen with the most efficient and stable suction nozzle
back-flushing principle. It can keep efficient self-cleaning performance and
work continuously with one single filter. The back-flushing does not interrupt
the water filtration process. Applied with LIVIC innovative design, GFK self-
cleaning filter is universal for various water types including the raw water.
It can run for a long-term without malfunction and maintenance. GFK series
self-cleaning filter reaches the international first-class level in the product
design standard, running performance and quality, which meets the most
demanding requirement of end users.



The water flows into the screen inside from the filter inlet, gets through the
screen and flows out from the outlet. The impurity particles are blocked by the
screen mesh. After the accumulation of more particles, the filtration pressure
drop rises to preset value (usually 50 KPa). The control system triggers the
cleaning sequences. Open the back-flushing valve A and the auxiliary back-
flushing pump. The gear motor drives the reciprocating scanner at the same
time. The dual-channel back-flushing tube moves helically and cleans the screen
inside with suction nozzles. Because the back-flushing valve A opens, the
differential pressure happens in the postion where group A nozzles contact the
screen. The differential pressure = outlet pressure - back-flushing outlet A
pressure. The outside filtrate reverse flow passes the screen and injects into
the group A suction nozzle inside. The impurities and particles on the inner
surface are flushed out by the reverse flow and the filter screen filtration
capacity is regenerated. After all the screen area is scanned and cleaned by
the suction nozzles, one back-flushing cycle is completed. During back-
flushing, the filtration goes on and Only very low fluctuation of flow rate and
outlet pressure happens.



Start the large particle back-flushing function by time mode after running for
a period. Keep back-flushing valve A closed and open back-flushing valve B. The
gear motor drives the group B suction nozzles to back-flush out the large
particles that cannot be removed by the group A suction nozzles, which will
avoid the malfunction resulting from accumulated large particles for a long
time.
