Chunke Water Treatment is one of the leading seawater desalination plant manufacturers in China. Our company was located in Guangzhou, near to Baiyun International Airport.
Chunke as reverse osmosis plant manufacturer from China established in 2009. And until now, has made over 1000 projects for seawater desalination plant. So, it makes us one of best seawater desalination plant manufacturers in China.
What is seawater desalination plant?
Sea water desalination plant use reverse osmosis membrane filtration technology. Hence, semi-permable RO membrane does not allow salt pass through reverse osmosis membrane’s pores. Because these pores size is about 0.0001 micrometer.

How to find seawater desalination plant manufacturers in China?
The best way is searching from Google, Alibaba or Made-in-China web pages accordingly. But, how you can be sure which one is the best seawater desalination plant manufacturers in China?
Because, in China there are a lot of trader companies, they just focus on sale their machine. So, Chunke as seawater desalination plant manufacturers in China, design and produce system as regards to customer sea water analysis report, application, customer factory layout and customer budget.
So, when you find a seawater desalination plant manufacturer from China, it is better to make video call or video meeting to see water treatment system producer’s factory.
Commercial Seawater Desalination Systems
As Chunke, we are providing commercial sea water desalination plant. Meanwhile, their size is between 50LPH to 2000LPH.

Commercial seawater desalination plant is using reverse osmosis membrane filtration technology. So, commercial seawater desalination plant is suitable for small size house, villa, curies, yacht, boat, small size business cooperation.
Here, you can see our video for commercial seawater desalination plant. As a result, Chunke is giving best quality and best price seawater desalination plant manufacturers in China.
Industrial seawater desalination systems
Chunke, also capable to produce big size industrial seawater desalination plant with reverse osmosis system accordingly.
Capacity Range: 38m3 to 2500m3/Day
Membrane Diameter: 8″
Working Pressure: 1200psi
Feed Water TDS: 20000 to 40000ppm
In some of our project we are using Ultrafiltration technology as former treatment to increase efficieny and SW RO membrane life.
We have greate experience on production of large size seawater desalination SWRO system as seawater desalination plant manufacturers in China. So, industrial seawater desalination plant is suitable for irrigation, drinking water and industrial process where you have water scarcity for fresh water.
Here, you can see our video for Industrial Seawater Desalination Plant.
What is the intakes method for seawater desalination plant?
We have details article and video for intaking seawater. Hence, there are three popular method to get water from sea or ocean.
- Beach Well Intake
- Subsurface Water Intake
- Open Seawater Intake
How does reverse osmosis system work?
Reverse Osmosis (RO) is a water treatment process that removes contaminants from water by using pressure to force water molecules through a semipermeable membrane. During this process, the contaminants are filtered out and flushed away, leaving clean, delicious drinking water accordingly.
Meanwhile, seawater Desalination Plant manufacturers in China are using different brands and design for the desalination machine.
We are using well-known international brand from USA, Europe and China. For example, we are using Grundfos, Danfoss, CNP or NYP pumps brands. For Seawater RO membranes, we are using DOW Filmtec, Hydranautics, Toray or Vontron accordingly.
Energy Recovery Devices (ERD) in seawater desalination plant SWRO
The high pressure pumping required to overcome the osmotic pressure in saline feedwater results in a saline concentrate stream which is highly pressurized. So, ERDs are commonly used to recover this hydraulic energy and transfer it to the feed stream, reducing both the amount of energy otherwise required by the HPPs and the size of HPP required.
The earliest ERDs used in SWRO plants were centrifugal-type devices such as the Francis Turbine, Pelton Wheel and Turbocharger. These devices convert the hydraulic energy of the concentrate into mechanical energy to drive a piston or pump, which transfers hydraulic energy back into the feed. Chunke as best seawater desalination plant manufacturers in China uses Donfoss Isave Energy Recovery Device.
Since around 2000, isobaric chamber ERDs have replaced centrifugal devices in most new SWRO plants. Isobaric ERDs transfer hydraulic energy from the concentrate directly into the feed, as the two streams come into direct contact (with minimal mixing). As a result of the single energy conversion, efficiency loss is reduced when compared with centrifugal ERDs.
