Ultrafiltration, which belongs to membrane filtration processes, is a pressure driven filtration technology.
The flux rate or the filtrate flow was assumed with app. 80l/m2h.
The total recovery of the plant is about 90% of the raw water inflow (at FNU
The cleaning can be accomplished by a so called „chemical enhanced backwash” (CEBW) with NaOCl for disinfection reasons once or twice a day. Additional a more intense cleaning will have to be made app. every three months.
A basic membrane filtration process diagram is illustrated in Graphic 1:
There are different processes to clean the feed water and to make a fresh drinking water. Next side it shows you the different contaminations and cleaning processes. Based on the contamination of the feed water, the cleaning processes are used optimally.
