Abstract
In this study the membrane performance of reverse osmosis (RO) elements along longitudinal direction in a pilot-scale plant with two CSM-2540 RO elements during municipal tap water treatment at the constant recovery and flux is investigated. The continuous cleaning process is carried out with fresh water cleaning. The membrane performance is monitored by the system and element pressure drop and the rejection. During add Tio2 (nano particles) in feed water with different concentration, with combined between different period for back wash and monitored the performance RO membrane.  Moreover, the performance of fouled membranes is restored by using the conventional cleaning protocol.  Soluble particles can enter the membrane pores and then build up on the pore wall, leading to a reduction in the total section area of the membrane pore, causing pore plugging into the membrane and increasing the membrane resistance. Membrane fouling is strongly influenced by solutions characteristics, operating conditions and membrane characteristics. The pumping power increases with increasing the fouling in membrane.  The TDS also increase with increasing the fouling, . A simple unit can be used for fast fouling processes using the nanofluid concentration as TIO2. in feed flow during the backwash process. The nanofluid and washing time use the main role played in increases in  RO system production. The SAW shape is the shape of the processes for all experiment. The maximum save in productivity is about 8.0% when using the washing time is 20 min.
