In this way, the dirt on the outer surface of this CF will blow out and come out from the FLUSH socket as waste water.
c) Filter cleaning mode
In this filter cleaning mode, the raw water will flow to the outer surface of the CF and comes out from the inner surface of this CF as shown in Fig. 9 above.
But instead of coming out to the OUT socket, this water will come out to the FLUSH socket as waste water.
The main purpose of this mode is to flush out any residue stuck on the inner surface of this CF during backwash operation.
