Processing technology of sea water supply for living

Seawater has a salinity of uneven around the world although most have salinity range from 3.1% to 3.8%. When the blend with fresh water flows from the rivers or near the glaciers are melting, the ocean water significantly lighter

1.    Salinity and other properties of sea water:

Seawater has a salinity of uneven around the world although most have salinity range from 3.1% to 3.8%. When the blend with fresh water flows from the rivers or near the glaciers are melting, the ocean water significantly lighter. Pale sea that in the Gulf of Finland, a part of the Baltic Sea. The most saline open sea (highest salt concentration) is the Red Sea (the Red Sea), due to the high temperature and the circulation is limited has created the high evaporation rate of the water surface as well as there is little fresh water from the mouth of the river empties into and little rainfall. The salinity of the sea water in the isolated sea (the sea sealed) such as the dead sea significantly higher.

The proportion of sea water is located in about 1,020 to 1,030 kg/m ³ at the surface also in deep oceans, under high pressure, sea water can reach specific gravity to 1,050 kg/m ³ or higher. Like the sea water is heavier than fresh water (pure freshwater reaches the maximum specific gravity is 1,000 g/ml at a temperature of 4° C) due to the additional weight of the salt and the electrical phenomena gynostemma pentaphyllum. T^[2]he freezing point of sea water is reduced when the salinity increases and it is around-2° C (28.4° F) in concentrations of 35 parts per thousan^[3]d. Due to chemical buffer, the pH of ocean water are limited in the range of 7.5 to 8.4. Speed of sound in seawater is about 1,500 m • s − ¹
2.    Sea water treatment processes for water supply for living:
Processing technology of sea water RO membranes use high pressure torsion
 
3.    Advantages of sea water treatment processes for water supply for living:
-Save groundwater in the ground
-output water quality guarantee QCVN 10:2008/BTNMT.
-power-saving for water treatment systems.
-easy to operate water treatment systems.
