RKSfluid Desalination Project-2019

  • Author:Damon Lee
  • Release on :2020-03-26


This project is the desalination project of the island of Vietnam by RKSfluid. We design, procurement, installation, debugging and acceptance of the desalination system are qualified. After the acceptance is passed, the owner can be given unified guidance training. The scale of construction is 15m3/h.

1.2 Design scope

1) Technical plan for seawater engineering.

2) Design and manufacture of mobile container desalination equipment.


1.3 Engineering Features

1) Saving land, all process equipment can be integrated in the container to meet the needs of seawater desalination system;

2) The construction period is short, all equipment can be integrated and installed in China, and only the pipeline connection is needed after the situation, which can shorten the construction period and reduce the labor cost;

3) The operation is stable, the seawater desalination process is advanced and mature, and the production can be stabilized, and the owner's worries can be relieved.


1.4 Description of seawater desalination process selection.

For the seawater desalination treatment project of this project, the whole seawater desalination system needs to be installed in the container container. Therefore, the selected seawater desalination process must significantly reduce the footprint when the effluent quality is met. Moreover, the materials selected for the process equipment must be resistant to salinity.

1. The seawater flows into the seawater collection tank. The seawater lifting pump is installed in the pool. The pump shaft and impeller are made of 2205 material, which is resistant to seawater corrosion.

2. The lifting pump raises the seawater to the active sand filter tank. The active sand filter tank can roughly filter out the impurities in the seawater and protect the subsequent processing equipment. The filter tank body is made of FRP.

3. The effluent from the activated sand filter tank flows into the activated carbon filter tank, and the activated carbon filter system can further remove impurities in the seawater.

4, activated carbon filter tank effluent into the security filter, and add scale inhibitor. The security filter guarantees the seawater quality of the influent reverse osmosis system, and the addition of scale inhibitors can reduce the membrane cleaning frequency.

5. The security filter effluent enters the reverse osmosis system. Reverse osmosis, also known as reverse osmosis, is a membrane separation operation that uses a pressure difference as a driving force to separate a solvent from a solution. Pressure is applied to the liquid on one side of the membrane. When the pressure exceeds its osmotic pressure, the solvent reversely penetrates against the direction of natural permeation. Thus, a permeated solvent, that is, a permeate, is obtained on the low pressure side of the membrane; and a concentrated solution, that is, a concentrate, is obtained on the high pressure side. The seawater is treated by reverse osmosis, fresh water is obtained on the low pressure side of the membrane, and brine is obtained on the high pressure side. The reverse osmosis system is the core process for seawater desalination. The reverse osmosis system is equipped with a chemical cleaning device to clean the membrane system according to the actual situation of the field data. The reverse osmosis produces concentrated water to pressurize the front end seawater by the action of the energy recovery device.

6. After the reverse osmosis treatment, the seawater enters the production tank through the UV disinfection device, and the water supply pump can supply water to each water point.
