5 Circulation
1) Open the UF washing liquid inlet valve 1# UF washing liquid outlet valve and 2# UF washing liquid outlet valve
2) Open the flushing pump inlet valve and outlet valve close the circulation valve open the safety filter inlet valve close the safety filter to UF outlet valve and open the safety filter air vent valve
3) Start the flushing pump when the preserve liquid drain from the air vent valve open the safety filter to UF outlet valve and close the air vent valve
4) Circulate the preserve liquid between the flushing device and UF unit one hour and stop the flushing pump
6 Preservation stop the flushing pump close the UF washing liquid inlet valve 1# UF washing liquid outlet valve and 2# UF washing liquid outlet valve
7 flushing
1) Flush the UF cleaning device
a) Open the clear water inlet valve start the secondary RO feed pump filling the flushing tank with the clear water
b) Open the flushing pump inlet valve and outlet valve circulation valve start the flushing pump to flush the flushing tank for 10mins
c) Stop the flushing pump open the flushing tank blow down valve and discharge the dirty water in the flushing tank
d) Open the clear water inlet valve filling the flushing tank with the clear water
2) Flush the flushing safety filter and chemical cleaning liquid inlet pipeline
a) Close the circulation valve open the flushing safety filter to UF outlet valve close the1# UF washing liquid outlet valve and 2# UF washing liquid outlet valve Open the up drain valve and the outlet drain valve
b) Start the flushing pump flushing the flushing safety filter and chemical cleaning liquid inlet pipeline
c) Stop the flushing pump when the flushing tank liquid level is low
3) Flush the UF unit
a) Open the UF up drain valve outlet drain valve inlet valve start the UF feed pump flush the UF unit
b) Open the UF inlet flashing valve outlet drain valve start the UF feed pump flush the UF
4) Flush the UF flushing backflow pipeline
a) Open the UF inlet valve 1# UF washing liquid outlet valve and 2# UF washing liquid outlet valve
b) Close the washing liquid inlet valve the UF outlet drain valve and up drain valve
c) Start the UF feed pump flush the UF flushing device pipeline and flushing tank 5min
Attention during the UF unit is preserved any operation is banned
