Seawater Desalination System

Desalination is a process that takes away mineral components from saline water. Saltwater is desalinated to produce water suitable for human consumption or irrigation. One by-product of desalination is salt. 

Sea water, Salt water, Brackish water Desalination

. First class high-pressure pump of corrosion-resistant, ultra reliable, high-performance.

Small size, low weight, easy to operating, installation and maintenance.

 Made in U.S (DOW) supreme quality Reverse Osmosis membranes for excellent desalination rate, durability and efficiency.

High-density 5-micron sediment filters to remove impurities from feed water during the pre-filtering process so as to extend the service life of Reverse Osmosis membranes.

Accurate real-time monitoring of the systems working pressures by top-graded meters specifically designed for maritime use. Real-time TDS water quality monitoring with digital display.

Water levels and over-pressure warning alarms with light and sound warning signals together with automatic shutdown protection to ensure the system is operating safely and properly.\

System equipped with Food Safety Level UPVC pipelines and premium quality 316 stainless steel valves and interfaces.

With heavy duty corrosion-resistant steel and anti-corrosion coated framework, the system is able to operate durably and stably under harsh environments with high temperature, high humidity and high salinity conditions.Working processRaw seawater tank→Booster pump→Sand filter→Activated carbon filter→5μm micro filter→1μm micro filter→High pressure pump→Seawater Reverse osmosis system (with Automatic RO backwash)→Output pure living water


Product Description

3m3/day seawater desalination system

Flow chart
Raw water tank→ Raw water pump→ Mechanical filter(quartz sand filter)→Active carbon filter→Sodium-ion exchanger(water softener)→Security filter→High pressure pump→Reverse osmosis→ 8. UV sterilizer (ozone generator) →Finished water tank

Function of each part of water treatment plant
1.Booster pump– provide the pressure to quartz sand filter/active carbon filter
2.Multi-medium filter– get rid of turbidity, suspended matter, organic matter, colloid, ect.
3.Active Carbon filter–Remove the color, free chloride, organic matter, harmful matter, ect.
4.Softener–exchange “ions” of calcium and magnesium with the most common and easiest method.
5.Security filter–prevent large particles, bacteria, viruses into RO membrane, accuracy is 5um
6.High pressure pump– Provide the high pressure to RO membrane
7.RO system– main part of the plant. The RO membrane’s desalting rate can reach 99%, removing over 99% ions
8.UV sterilizer or ozone generator- kill bacteria
