in the present study, the production of low-salt water from salty water by nanofiltration as well as membrane fouling was investigated. furthermore, a new method was proposed and tested experimentally for creating the backpulse in order to minimization of fouling and increase of the filtration efficiency. in the proposed method, the permeate was used instead of gas for creating the backpulse. t...

An experimental investigation of the cake filtration behaviour of 125-180 pm polyethylene particles, suspended in a neutrally buoyant Newtonian fluid, has been carried out. Static cake filtration measurements of both filtrate volume out-flow and cake thickness kinetics show the familiar t”” time dependence. In addition, the hydraulic resistance of the cake was found to be pressure independent, ...
