low project investment, low operating cost, high desalting rate, large water production, wide range of PH value application. World seawater desalination techniques are mainly reverse osmosis, multi-stage flash, vapor compression distillation, electrodialysis, freezing and etc. at present. After many years of actual operation, reverse osmosis has been the preferred mature technology widely used in seawater desalination engineering of various countries. Compared with other seawater desalination techniques, reverse osmosis owns the advantages of low project investment, low operating cost, high desalting rate, large water production, wide range of PH value application, short construction period, easy operation and control, etc.A new seawater desalination equipment mainly for desalting and purifying treatment of seawater. The treated water meets the national drinking water standard GB 5749-2006. It can be supplied for ship life drinking.Equipment features    1. It adopts advanced pre-processing materials to enhance the performance precision of auxiliary processing system, reduce the workload of reverse osmosis system and reduce the use of anti-scaling agents. So the device's overall life extends more than 3 times before.    2. Equipment's body adopts stainless steel and corrosion-resistant and rust-proof materials to ensure that no corrosion damage occurres on equipment containers, pipeline frames and etc. in 20 years.    3. It adopts multiple automatic control valves and powerful flushing and back-flushing device. The depositions in the membrane can be flushed thoroughly to drain. It ensures water volume and stable pressure.    4. It combines reverse osmosis components with multi-level advanced pre-processing materials to make the desalting rate get more than 99%. It can completely remove the harmful ingredients of inorganic salts, heavy metals, organic matters, bacteria, viruses and etc. in seawater to ensure water quality exceeds national drinking water standard.    5. With precise instruments display systems of flow, pressure, conductivity, PH value and etc., it can detect the operating status of equipment at any time to ensure the safety and stability of its water production.    6. Equipment owns the features of compact structure, costly appearance and small footprint. It can be adjusted and assembled according to engine room size.
