Medium Large Pipeline Raw Pure Sea Water Desalination Equipment Machine For Freighter Tanker


Specification

Medium and Large Seawater Desalination series

Medium and Large seawater desalination equipment is applied to freighter, tanker, drilling platform, island, water shortage city.

The RO system .adopts the most advanced membrane component and the most advanced system software, which combined with efficient energy recovery technology.

It can remove mineral salt, heavy metal ion, organic bacteria, germ and so on effectively to turn sea water into drinking water that meets standards GB5749-2006.

The whole system has equipped advanced flow meter, pressure control meter and safe pressure relief device, as well as advanced observation system to ensure the system running smoothly and product quality fresh water and provide accurate value.(When the TDS of production water exceed standard value, the system opens drain value automatically to discharge water)



Reverse osmosis

Usually called ultrafiltration method, it is a membrane separation desalination method that was adopted only in 1953.

This method uses a semi-permeable membrane that only allows solvents to permeate but not solutes to separate sea water from fresh water. Under normal circumstances, fresh water diffuses to the seawater side through the semi-permeable membrane, so that the liquid level on the seawater side gradually rises until a certain height is stopped. This process is permeation. At this time, the static pressure of the water column above the seawater side is called osmotic pressure.

If an external pressure greater than the osmotic pressure of the seawater is applied to the seawater side, the pure water in the seawater will reverse osmosis into the freshwater. The biggest advantage of reverse osmosis is energy saving. Its energy consumption is only 1/2 of the electrodialysis method and 1/40 of the distillation method. Therefore, since 1974, developed countries such as the United States and Japan have successively shifted their development focus to reverse osmosis.

The reverse osmosis seawater desalination technology is developing rapidly, and the engineering cost and operating cost continue to decrease. The main development trend is to reduce the operating pressure of the reverse osmosis membrane, increase the recovery rate of the reverse osmosis system, cheap and efficient pretreatment technology, and enhance the system's anti-pollution ability.
