What is desalination?
desalination is removed by salt and other marine water particles, brackish water and obtains waste water, which makes it drinking. With regard to drought, increase in population and change in the infrastructure of drinking water purification, the desalination methods have appeared as popular, affordable and necessary. Through distillation and reverse osmosis, water treatment plants can remove most of the salt and dirt from salt water, providing a clean and enjoying supply.
Experts agree that we are quickly running out of freshwater water necessary for drinking, washing and irrigation. Because there are plenty of salt water in the ocean, scientists have developed processes that can remove salt and dirt and create fresh water. Some processes can be carried out in coastal races and others in municipalities. At this point in technological progress, the desalination costs are increasingly higher than the cost of transporting fresh water from other sources, with the exception of desert areas such as West Asia.
distillation is one of the desalination methods. Distillation uses evaporativeTo separate dirt, such as salt, from pure water. The water must be heated until it is evaporated, so clean water rises when the steam and particles remain in the water brine. The steam condenses in the next collection container while the brine is released. Distillation has the advantage of using thermal energy such as sunlight, saving electricity costs. However, it creates less fresh water as a percentage of unclean water, a measure of recovery than reverse osmosis.
Another common desalination method is reverse osmosis. In the reverse osmosis, the supply water can be either salt water or obtains "gray" water from the supply of urban waste. The fan force pushes the supply water through the membranes with pores that allow the water molecules to penetrate but do not allow salt and pollutants. A number of filter membranes, with progressive sensitive membranes, are more efficient and do not respect easily. Reverse osmosis requires a lot of electricity to power the valvesIt can also boast of almost 50%recovery levels.
If we are to continue our use samples, country around the world must reassess its drinking water sources. Especially in the desert climate bordering on the ocean, the answer can be designed. Its technology is still improved, but there are many research organizations that work to minimize costs, public education, encourage the construction of desalination plants and eliminate all health risks associated with regenerated or contaminated water.
