Seawater Desalination Plant from NEWater

Desalination plants can treat and utilize abundant seawater resources. The production capacity of the seawater water desalination plant can reach 600 cubic meters per day.

The basket screen can screen out sundries, sand, and gravel in the seawater, and after a series of treatments such as coagulation, flocculation, and filtration, fine suspended solids can be removed.

Reverse osmosis has always been the core technology of desalination plants. The seawater is pushed by the pressure pump to the RO semipermeable membrane that only allows water molecules to pass through so that most of the salt in the seawater is blocked outside the membrane. Therefore, part of the water is filtered and desalinated, and the other part is returned to the sea as concentrated brine. Seawater undergoes two stages of reverse osmosis, which can increase the salt removal rate, and the salt removal rate can reach 99.7%.

The purified water can not be used directly as process water, mineralized drinking water, or boiler make-up water after further purification, so as to realize the utilization of seawater resources.

This specialization ensures they are adequately effective in desalinating seawater and differentiates them from other desalination systems. The principal desalination technique used in seawater desalination plants is reverse osmosis. Underneath are some of the basic components of a RO seawater desalination plant:

• Water source: Seawater.
• Pre-treatment chamber, which entails filtration to remove debris and seaweed.
• High-pressure pumps to generate adequate feed water pressure.
• Semi-permeable membranes, eliminate dissolved salts, microorganisms, and other organic pollutants.
• Post-treatment chamber regulates the alkalinity levels of the feed water and mitigates organic growth.

➣What are the Various Applications of Seawater Desalination Plants?

The limitless availability of seawater coupled with the scarcity of freshwater has tremendously increased the number of individuals, industries, and businesses reliant on desalination systems.

➣What Desalination Methods are Utilized in Seawater RO Desalination Plants?

There are mainly two desalination processes deployed to eradicate dissolved salts and other impurities from seawater. The scale of application and power supply often influence the choice between a thermal process and a membrane-based process. Here is a brief description of the prevalent seawater desalination technique.

Reverse osmosis.

Reverse osmosis is the predominant seawater desalination mechanism in use across the world. It is a membrane-based technique, which utilizes high-pressure pumps, filters, and perforated membranes for effective desalination. At first, the seawater is directed into a pre-treatment unit where it is subjected to chemical dosing and filtration. This eradicates huge constituents found in seawater such as seaweed and suppresses corrosive chemicals that may cause the plant to rust.

Subsequently, the high-pressure pumps at extreme pressure (often 600-1200 psi) force the water into the semi-permeable membranes. The perforations on the membranes are extremely small (around 0.0001 microns) meaning they trap the dissolved salts and other smaller constituents such as arsenic and protozoa. Finally, the water is taken through a post-treatment unit to regulate the PH levels.

➣How Does a Seawater Desalination Machine Function?

The functional details of a seawater water desalination plant are contingent upon the desalination process it exploits. Thermal desalination and reverse osmosis are the two commonly used desalination processes in seawater desalination plants.

Thermal desalination.

Simply put, thermal desalination is an imitation of the ordinary rain-creation process. Seawater is heated to a point of evaporation, condensed, and finally collected as fresh potable water. Dissolved salts and other contaminants cannot turn into vapor explaining the principle behind thermal desalination. This process is often categorized into:

• Vapor compression.
• Multi-effect distillation.
• Multi-stage flash distillation.

Reverse Osmosis.

Reverse osmosis, on the other hand, is founded on semi-permeable membranes and filters. RO seawater desalination plants have pre-filters, which initially eject large constituents from the seawater before forcing the water via a perforated membrane. The small-sized pores of the membrane in turn reject the dissolved ions, unwanted minerals, and microorganisms, therefore, generating clean potable water.
