Removal of Suspended Solids, Algae and Turbidity from the Raw Water and Enhancement of Desalination of Saline Water using an Innovative Membrane Filter

Today, one of the most basic needs of human life is fresh and clean water. Because of remarkablereduction of fresh water resources and increasing of water pollution, purification of contaminated water isnow a concern. One of the major difficulties that purification procedures such as reverse osmosisencounter, is turbidity of water flowing into purification system. Turbidity causes block in the membranesof these devices, so they can’t work anymore. Because of high costs of maintenance, low efficiency, largespace and time consuming and difficulties in design and implementation, sand filter is not a good choicefor pretreatment of water containing turbidity.To overcome these hardships, Khorasan Razavi Rural water and Wastewater Company, as a researchplan, invented a pretreatment filter to reduce turbidity of water from more than ۱۰۰۰NTU to less than۱NTU to prevent of damage to the membrane of desalination devices. The filter was tested both inlaboratory and field implementation successfully
