With the ever-increasing population and growing economy, the continuous supply of water has become more and more difficult. Therefore, the water recycling or water reuse is the future development in water purification technology to ensure the reliability of water to public use. Currently, membrane technology especially reverse osmosis has been installed widely in water purification technology mainly in recycling of wastewater and ultra-pure water production. However, a crucial drawback of membrane is their susceptibility to fouling due to the organic fouling and biofouling which may reduce the lifetime of membrane and increase the operating cost. According to the literature and membrane specification criteria, membrane pretreatment is the prerequisite to hamper the membrane fouling. In order to set up the membrane operating criteria and respective applicable standards, the investigation of different uses of recycled water, the effectiveness of membrane must be analyzed. In this study, various characteristics in effluents (domestic wastewater, industrial wastewater and potable water) will be studied to reduce the membrane fouling problems to enhance water production qualities. The various pretreatment methods to different membrane systems will be evaluated in lab scale membrane systems in term to assess the optimum pretreatment with different types of membranes and water quality parameters. The results will be premeditated by the capability in removing pollutants (suspended solids, dissolved organic matters, microorganisms, emerging contaminants), analytical economic and operational assessment in criteria of membrane and pretreatment selection. Lastly, the results will be compared with the water recycling and reuse parameters and economic cost analysis assessment, operation and maintenance of membrane cost will be studied to develop the optimum membrane technology technical guidelines for water recycling.水回收再利用薄膜前處理技術結垢控制薄膜技術準則建置water recyclingmembrane pretreatmentfouling controldevelop guidelines for membrane process
