Product Description

The Seawater Desalination Device adopts the international advanced reverse osmosis technology and is designed by optimizing the system.

We have specially designed according to the special application of the ship, featuring small size, light weight, land occupation, convenient installation and strong adaptability. Applicable to yachts and fishing boats, the equipment is easy to operate and maintain. As long as it provides sea water, power supply, start-up and water production, the equipment has high salt rejection rate, stable performance, safety and reliability, and novel design.

The system can effectively remove inorganic salts, heavy metal ions, organic bacteria, bacteria and other harmful components in seawater, and desalinate seawater into high-quality water in accordance with the National drinking Water Sanitation Standard (GB5749-2006).

Net weight

* 1. The amount of water produced refers to the amount of water produced under the conditions of an inlet water temperature of 25 ° C, a salt content of 35,000 mg/L, and an operating pressure of 4.5 MPa.
   2. Equipment can be customized according to customer requirements.

System function

1. High-pressure unloading, when the high-pressure pump outlet pressure exceeds 6.2MPa, the equipment automatically stops and protects and emits an audible and visual alarm.
2. Low-pressure shutdown protection. When the pre-treatment water supply is insufficient and the high-pressure pump inlet pressure is lower than 0.05MPa, the protection action will be automatically stopped and an audible and visual alarm will be issued.
3. The pre-treatment is equipped with a manual multi-way valve for large-flow backwashing and full washing.
4. Configure the reverse osmosis membrane cleaning system to physically clean, chemically clean and refill the reverse osmosis membrane module.

5. Automatic efflux of produced water quality exceeding standard.

Reverse Osmosis Technology

The reverse osmosis membrane is an artificial semipermeable membrane made of a semi-permeable membrane that has certain characteristics and is a core component of reverse osmosis technology.

The principle of reverse osmosis technology is to remove these substances and moisture according to the osmotic pressure of the solution, according to the fact that other substances cannot pass through the semipermeable membrane. The membrane pore size of the reverse osmosis membrane is very small, so that dissolved salts, colloids, microorganisms, organic matter, and the like in the water can be effectively removed.

The system has the advantages of good water quality, low energy consumption, no pollution, simple process and easy operation.
