  1. Desalination Plant: An effort to Mitigate Drinking Water Crisis of Southwest Coastal Region of Bangladesh Presented by Noor Ahmed Project Coordinator Prodipan

  2. Impact of Saline Water Intrusion in the Southwest coastal region of Bangladesh Impact on Drinking Water Impact on Livelihood Impact on Environment/ Ecosystem Impact on Health Impact on Agriculture

  3. Source of drinking water in the salinity affected area Rainwater Harvester Pond Sand Filter (PSF) Pond Tube well

  4. Limitations of PSF, Rain Water Harvester, Pond and Tube well Cannot remove Salinity Cannot not supply water whole the year Not free form viruses and bacteria Cannot remove dissolved solid (such as arsenic, calcium, magnesium, iron, odor, color and so on) Output rate is low Micro organism grow after two to three months

  5. An effort of Prodipan to mitigate drinking water crisis of southwest coastal region of Bangladesh Prodipan has installed a desalination plant in the upazila of Sarankhola of Bagerhat under the project of Rehabilitation support for the victims of cyclone Sidr 2007. Desalination Plant Control Panel

  6. Main mechanism of desalination plant: The main mechanism of desalination plant is reverse osmosis. Reverse osmosis is a liquid filtration method for removing many types of large atomic molucules from smaller molecules, by forcing the liquid at high pressure through a membrane with pores (holes) just big enough to allow the small molecules to pass through. It is most commonly known for its use in drinking water purification from seawater, removing the salt and other substances from the water molecules.

  7. Demand of desalination plant water Demand of desalination plant water is tremendous Our plant capacity is 1000 liter/hour but the demand is more than supply. We are running desalination plant from January 2010 and our average sale is 1000 liter per day.

  8. Advantages of Desalination Plant Remove salinity Produce pure, clean and potable water Produce viruses, bacteria and diseases free water Remove all kinds of dissolve and suspended materials and chemicals (such as arsenic, calcium, magnesium, iron, odor, sediment, color and so on) Output rate is high Initial installation cost is relatively high but considering long term it is most appropriate technology for salinity water treatment

  9. Some Key Feature of desalination Plant Installation Cost is approximate 10 lac for 1000 liter/hour plant Per liter production cost is 0.35 paisa (plant run by diesel generator) Per liter production cost is 0.25 paisa (plant run by electricity) Production cost depends on plant capacity

  10. Challenges of Desalination Plant Installation cost is relatively high Needs skill person to operate Operation and maintenance cost is relatively high Needs electricity to run the plant Safe and secure place is needed for desalination plant Community based management with finacial contribution
