Marine RO System -2540 plants can be standardized production,all plants of this series use the model 2540 of RO membrane.
The Reason Why You Should Trust Us ！
PLC Control System
- Ensure complete automatic running
- Ensure automatic clean total system with fresh water
PLC Control can reduce manual manipulation and the risk of operating errors.So that it could protect the seawater desalination plant can normal operation for a long time.
- Automatic clean multi-media filter with multi-way valve
- Innovative two security filters
To protect the reverse osmosis membrane from becoming clogged by solid particles that can be suspended in the seawater. The seawater is filtered before passing through the membranes.
Reverse Osmosis Membrane System
- DANFOSS High Pressure Pump
- DOW RO Membrane
- ROPV Pressure Vessels
- 316L Stainless Steel Fittings
- UPVC & 316 Stainless Steel
To guarantee the system reliable connection,
About Marine Seawater Desalination Plants
Sea water contains high suspended solids(SS),dissolved (TDS)& bacteria,is not suitable for human use or irrigation.
Sea water can be made usable by reducing the SS,TDS and bacteria to recommended levels.
In this process, the SS reduction is done by multimedia filter followed by cartridge filter as pre-treatment before RO membrane.The bacteria and TDS reduction are accomplished by RO membrane.
RO membrane is a reduction process to remove larger particles from raw water. In RO,an applied pressure is used to overcome osmotic pressure.Reverse osmosis can remove many types of molecules and ions from solutions, including TDS &bacteria.The result is that the solute is retained on the pressurized side of the membrane and the pure solvent is allowed to pass to the other side. To be “selective”, this membrane should not allow large molecules or ions through the pores (holes), but should allow smaller components of the solution (such as the solvent) to pass freely.
The capacity of fresh water production depends on a number of factors:
1. The operation pressure.
2. The salt content of the feed water
3. The feed water temperatures
Each standard system has been designed for a certain production rate of pure water,assuming the feed water Temperature is 25℃.For each 1℃ drop in feed water temperature, the permeate production drops by 3%.For example:Designed output at 25℃ is 100l/h, then with a feed temperature of say 15℃,the permeate output is reduced by 30%, i.e 100l/h(1-30%)=70l/h.
Design point is 25℃ feed water with 35,000ppm TDS. Operation at other conditions will vary output.
