| dc.description.abstract | Fresh water scarcity is becoming a serious problem in many regions of the world. Desalination is an common solution to supply fresh water. Desalination is a process that removes dissolved ions from sea water, brackish water and waste water. There are many technologies of desalination including multi-effect desalination(MED), multi- stage flash desalination(MSF), electro-dialysis(ED) and Reverse osmosis(RO). Reverse osmosis is widely known technology for the production of fresh water from sea water. The performance of sea water reverse osmosis(SWRO) desalination is influenced by several factors including feed water properties and operation variables such as sea water salinity, temperature, pressure etc. In this paper, Outside-in hollow fiber ultra filtration(UF) membranes were adopted as the pretreatment prior to SWRO process. First of all, the experiments of pretreatment were preceded to find proper operating condition of UF membranes. The trans membrane pressure(TMP) and permeability were calculated, turbidity and silt density index(SDI) at input and output of UF membranes were measured. After that, the experiments were carried out to investigate the influence of sea water salinity on SWRO membranes performance. Sea water salinity of SWRO membranes was changed from 33,000ppm to 47,000ppm. The experimental results indicate that SWRO membranes were sensitive to sea water salinity | - |
