Reverse osmosis seawater/brackish water desalination equipment

Reverse osmosis seawater/brackish water desalination equipment is an efficient water treatment system based on membrane separation technology, which separates salt and water through high-pressure driving. It is widely used in coastal areas, islands, and brackish water distribution areas. The following is an analysis of its core technologies and applications:

一、 Technical principles and core components

1. Reverse osmosis membrane separation

Using a semi permeable membrane (with a pore size of approximately 0.1 nanometers) to selectively permeate water molecules under high pressure (5-8 MPa), intercepting salt, organic matter, and microorganisms.

The film material is polyamide composite film, which is corrosion-resistant and has a long service life.

2. System composition

Pre processing unit: Multi media filter+activated carbon adsorption to remove suspended solids, colloids, and residual chlorine.

High pressure pump: provides stable pressure (such as plunger pump), with reduced energy consumption compared to distillation method.

Intelligent control system: Real time monitoring of water quality (conductivity, turbidity) and adjustment of operating parameters.

二、 Typical application scenarios

1. Islands and coastal areas

To solve the problem of freshwater shortage, for example, coastal cities in China can achieve a daily supply of 100000 tons of freshwater through reverse osmosis equipment.

Small equipment (such as shipborne) can meet the water needs of fishermen or island troops.

2. Industry and Agriculture

Provide boiler feedwater for power plants and chemical plants to reduce the risk of scaling.

After desalination of brackish water, it is used for irrigation in farmland to increase crop yields.
