The problem at hand is the fact that the climate is changing due to atmospheric pollution from burning fossil fuels. Burning fossil fuels causes CO2 emissions that are causing climate change. Climate change directly affects supplies of fresh water causing natural water supplies to dry up creating droughts. These droughts can be so bad in some places that people will not have enough freshwater to survive. One method used to help this problem is water desolation.Water desolation is a process that removes salt and other minerals from water to make it fresh and clean so people can use it and drink it.

Reverse Osmosis works by filtering salt (sea) water through a fine membrane, and discharging the salt overboard and harnessing the filtered clean water. The pump pressure must be higher than the osmotic pressure in order to force seawater flow through the membrane and permeate water out of the module. The flow rate is proportional to the difference between the two pressures. When they are equal water does not flow through the membrane, and if the pump pressure is lower than the osmotic pressure, permeate water will flow back towards the concentrated salt water. ([])

The amount of carbon dioxide can be found using stoichochemistry.

system is capable of producing a large volume of water in a pretty efficient time. The system’s products are explained in this video. [] [|http://urila.tripod.com/Seawater.] []

The world's largest desalination plant is the Jebel Ali Desalination Plant (Phase 2). It's a dual-purpose facility that uses multi-stage flash distillation and is capable of producing 300 million cubic metres of water per year, or about 2,500 gallons of water per second. By industry estimates, more than $120 billion will be spent toward developing water and wastewater infrastructure in the MENA region, one of the world's driest regions, over the next decade. Saudi Arabia, Egypt and the UAE are poised to lead that initiative.
