Desalination has been proven as a process that works in providing clean and drinkable water for the community. One advantage of desalination is that it prevents the country from having to depend on precipitation to ensure an adequate amount of water supply.
It is estimated that the desalination plant is able to produce at least 500 millions liters of water. The plant usually does not occupy much spaces and is the same size as the warehouse. There are two most common types of technologies being used in desalination process. The distillation process makes use of evaporation to separate salt and mineral from the water.
Reverse osmosis, on the other hand, is a filtration system consists of a number of membranes where the water must pass through. Reverse Osmosis (RO) is more effective compared to distilled water process.
The Middle East region has the highest number of desalination facilities because their dry weather causes shortage of water supplies from other sources.
North Africa is another region that utilizes desalination to provide clean water for its people. Developed countries like USA and Europe have also installed desalination plants to cope with water shortage problems.
Desalinated water is a good alternative because the water is always available regardless of the climate. With desalination, a community no longer have to depend on water sources that are located far away. It prevents the people from exploiting exhaustible water supply sources such as mountain streams and rivers.
Desalination companies can be built to supply safe drinking water to cope with emergency situation. For example, desalination facilities can produce clean water for army operations.
The desalination technology is still undergoing improvement to reduce the harm that it does to the environment. The two main disadvantages of desalination is damaging the marine life and high level of greenhouse emissions.
The brine discharged by the desalination plant after processing the water contains two times more salt content compared to the seawater. However, the negative impact of brine discharge can be minimized by abiding in the strict standards of the environmental regulations.
The establishment of desalination plants all over the world can help to bring improvement on both the economic and social aspects of the country. Desalination allows the region to have its own independent water supply without having to keep importing water from other areas.
Population growth in a country is one reason why more desalination plants need to be built. Many people have tasted desalinated water and rated it either as good or excellent. Many cities rely on large desalination companies to provide clean filtered water that is safe for drinking.
The reason is that there is a lot of costs involved in building desalination plants. Large desalination companies have the capitals to purchase the desalination equipment without facing any possible financial risk.
The cost for desalination is higher than other water supplies. However, many desalination companies have successfully reduce the cost by building the plants nearby to the ocean and cutting down the distances of the pipes to the town.
