ISO9001 Marine Seawater Desalination Plant / Flexible Design Ocean Water Purifier
Working Principle
Seawater desalination system push the feed water through multi-media filter (sand filter ) to hold up huge particles and suspended solids. When the filtrated clean seawater is continues pressurized up to 50 to 60 bar into the reverse osmosis system by high pressure pump. It separates the remaining salts, minerals, and impurities through the semi-permeable membrane. Fresh water is obtained, and the concentrated water is discharged accordingly.
Technical Processes
Feed water tank→Feed water pump→Multi-media filter→5um security filter→1um security filter→High Pressure pump→RO System→Energy recovery device (Optional)→CIP system→Fresh water tank
Main features of sea water desalination unit
1. Offering flexible design for muti purpose of commercial / navy ship, engineering barge, offshore oil drilling platform, island water station & coastal facilities.
2. Wide range of treatment capacity is subject to practical demands from 5~3000 m3/d.
3. Inflow and outflow monitoring records indicate real-time working condition.
4. Can be automatically controlled by PLC integrated system in one push button.
5. Regular chemical dosing & flushing setting software makes sure desalination unit working in good shape.
6. Long life span and high salt rejection RO membrane decrease operation and maintenance cost.
