The Marine Two-stage Membrane Reverse Osmosis Seawater Desalination Device adopts the international advanced reverse osmosis technology and is designed by optimizing the system.
We have made a special design according to the particularity of the ship's application, which has the characteristics of small size, light weight, low land occupation, convenient installation and strong adaptability. It is suitable for offshore operation platforms, oil tankers, etc. The equipment is easy to operate and maintain. As long as sea water and power are provided, water can be produced after startup. The equipment has high desalination rate, stable performance, safety and reliability, and novel and ingenious design.
The system can effectively remove harmful components such as inorganic salts, heavy metal ions, organic bacteria and germs in seawater, and desalinate seawater into fresh water.
Scope of application: water production is 1250L/ hours, and the fresh water produced is used to supply fresh water tanks, drinking water tanks, cooling water tanks, and distilled water tanks on board to meet the service requirements of domestic water and equipment water on board.

* 1. The amount of water produced refers to the amount of water produced under the conditions of an inlet water temperature of 25 ºC, a salt content of 35,000 mg/L, and an operating pressure of 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. When the salt content of the fresh water exceeds the specified value, the unqualified fresh water is automatically discharged and an alarm signal is 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.
Process flow diagram
1. Feed pump: Equipped with a stainless steel pump, to provide sufficient pressure for subsequent filtration.
2. Multimedia filter: Mainly to remove turbidity, which is used to filter out large particles and suspended solids in raw water.
3. Precision filter: Further filtration, protection of reverse osmosis membrane.
4. High pressure pump: Provide enough pressure for reverse osmosis system.
5. Reverse osmosis system: The core part of pure water equipment, the production of high-purify water.
Main accessories
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.
Packaging: International standard export package; And we can pack according to customers' requirement.
Delivery Time: 25 Working Days.
