Is the seas to remedy water attack?

The water treatment plants are added a new one day. The treatment process that needs intense energy consuming but can damage the environment from different angle. [[T][4][[T]]
[[ It is highly revitalized in recent years to get fresh water from flowing water. With its treatment facilities, it is necessary to add the freshwater sources that are difficult to increase. The country, which determines the head, for years, is solved by sea water. Singapore and its neighbor Malaysia are trying to reduce on fresh water with this method. Israel has a 500 million cubic meters of sea water in the year. “As long as saltwater diarrhea, high quality sweet water can be obtained. The oceans are quite large. Very largeweight of salty water can be eaten without any damage. This is not possible in the ecological systems of the river and lake. But what there is, saltwater leads to more energy consumption than water treatment in the river and lakes. This is also the biggest problem in the USA, Yale University, who spoke in the form of environmental technologies, Professor Menachem Elimelech, warn that it seems to be the most ideal solution to get rid of water attacks at first glance. ARITMA PROCESS IS LOOKING FOR THE ENVIRONMENT? At the wind of the environmental negative effects of water treatment, carbon dioxide release comes. “In seawater there is seaweed, which can distinguish salt as well as many others themselves. Available membrane work quite well on the slope of water. However, organic matter and damaged functions in the case of ventilation to these membrane filters. While organic substances are collected in the top parts of the filters, William Phillip from the University of Notre Dame in the Indiana State of the USA, pay attention that the use of wind or solar energy in plants can be reduced by carbon dioxide release. ]]]]The CHEMICAL ARTICLES US ] What IS THE LESSONS? Professor Menachem Elimelech, hungry in environmental technologies, pay attention to a different problem that may arise in the future of the destruction of salts from the treatment of semi-salinated water in the address of the sea to remote places“One of the ways of the solution can pump the salt phrases to the underground of about 1 kilometer. This is not a permanent solution, but there is a kind of disposal method. In the case of pumping underground to destroy salts of treatment plants can damage underground waters in 50, 100 or 500 years" [ If the water treatment is predisposed to cushion at first glance, the treatment process negative energy usage and can damage the environment from different angle. Professor Elimelech will not be another option than salted water treatment in many drowns. However, it still states that before resorting to this method, more friendly technologies should be taken into consideration.
All modern saltwater treatment plants are based on the principle of reverse omosis. In the reverse osmosis process, all unwanted appetite in the water are snacks from water and passes through an filtration process. When salted water is applied, a rather high pressure is applied and 3 to 4 kilowatthour electricity is used for a sweet water. Three times more carbon dioxide is produced in saltwater treatment compared to the purification of river and lake water. [
]]Membrans pour chemicals before treatment the seawater to reduce the flavor of such organic substances. While many foods are trying to develop a new microbes decomposing, which is among factors that may have negative impact on the environment.
]It is also quite important in the process of getting sweet water, how to destroy decomposed salts. In general, only stacks are reloaded in the sea, for quickly dissolving. When there isn’t enough a long-term research, it doesn’t know what kind of side effects for salts to sea coils, sea creatures.
