Containerized seawater desalination equipment

Containerized seawater desalination equipment
Container box -type seawater fading system(The container equipment can be designed according to raw water treatment, raw water can be: sea water, rivers, river water, lake water, tap water, groundwater, etc.)

The container -style seawater fading equipment adopts reverse osmosis technology. From the seawater water removal system, first roughly filter and reduce the turbidity of the seawater, and then use a high -pressure supercharged pump to enter the reverse osmosis membrane. Reduce water into a dilute water tank, and the quality of water out of water meets the requirements of living water (the sanitary standard of drinking water (GB5749-2006)).

The containerized seawater desalination equipment is assembled for the seasonal freshwater supply of the living water or tourism industry with deficiencies of freshwater, as well as
freshwater requirements in remote areas or urgent conditions. In a short period of time, it can quickly organize production and supply, less investment, and fast results.

Containerized seawater desalination equipment adopts self-developed water treatment process, which has been well received by many customers after years of practical application. Seawater desalination treatment equipment is mainly used for domestic drinking water treatment of ships, ships, offshore platforms, and islands.
