Product Description
The aquaculture seawater desalination equipment adopts the international advanced reverse osmosis technology and is designed by optimizing the system.
It has the characteristics of small size, light weight, space saving, easy installation and strong adaptability. It is suitable for land and island. The equipment is simple to operate and easy to maintain. As long as the seawater and power are provided, the water can be produced after startup. The equipment has high desalination rate, stable performance, safety and reliability, and novel and clever 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 (GB5749-2022).
When used in aquaculture, the equipment can quickly perform seawater concentration treatment to increase seawater salinity, and the concentration multiple is 2-10 times.

* 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 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 an 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.

Features and advantages
● High quality imported high pressure pump with high operating efficiency, low energy consumption, low noise and long service life.
● High-quality reverse osmosis membrane with a salt rejection rate of 99.5%, strong anti-pollution ability and stable water quality.
● Rack piping and fittings are made of stainless steel and corrosion-resistant materials to ensure long-lasting equipment and low maintenance costs.
● The operation is simple and easy to use, and the maintenance is convenient. As long as there is electricity, there is sea water, and fresh water can be supplied immediately after the pipeline is started.
● Easy to install and easy to migrate: the production and assembly of skid-mounted equipment are completed in the factory, the field installation work is less, only need to complete the interface pipeline and external electrical connection to work; because the functional components are integrated in a whole base Can be easily migrated as a whole.
● Wide range of power supply: 220V~440V/50~60HZ.
● RO product water quality standard: in line with national drinking water standard <GB5749-2022>.
● Long service life: 15-20 years, rigorous process design to ensure long service life and low maintenance costs.
● The type of equipment combination can be realized: bracket type, armored type, brake type, container type, etc.
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.
