I.membrane filters description
UF is a separation technique similar to that of Reverse Osmosis (R0). The main differences between the two are that: RO separates virtually all dissolved molecules (ions), while OF retains molecules above a certain size and allow some smaller molecules (ions) to pass through as product, OF
are rated according to the molecular weight (MWCO) of the solutes removed;

IV.membrane filters Cleaning
The chemical cleaning depends upon the pollutants type of inlet water. Only backwash cannot wholly remove the scolds, which causes the degradation of UF performance over time. In order to recover the previous filter performance, chemical cleaning is necessary. The leaner can be acid, sodium hydroxide, sodium hypochlorite, disinfectants.
