Seawater desalination plant

Definition of seawater desalination

 

Desalination is the production of fresh water by desalting seawater. It is an open source incremental technology to realize the utilization of water resources, which can increase the total amount of fresh water, reverse osmosis method and is not affected by time, space and climate, good water quality and reasonable price, which can ensure stable water supply for coastal residents and industrial boilers. At present, the reverse osmosis method using reverse osmosis membrane rapidly occupies the market with its advantages of simple equipment, easy maintenance and modular equipment, and gradually replaces the distillation method to become a widely used method.

 

Marine desalination equipment

 

Full consideration of customer requirements for design and production, according to the particularity of ship applications and special design, its small size, light weight, energy-saving, easy installation, strong adaptability, can be installed in narrow crowded cabin, deck, crew cabin, aisle and other Spaces. The equipment is simple to operate and easy to maintain, as long as there is seawater and electricity, fresh water can be provided immediately after startup. The equipment has high desalting rate, stable performance, safe and reliable, novel and ingenious design, avoiding frequent cleaning and no environmental pollution. Its frame is made of stainless steel, rust resistant and corrosion resistant. Wide range of power supply (220-380415V/50HZ/60HZ/ three-phase), can adapt to most of the domestic production of ships. Desalinated water quality in line with the national drinking water quality standards.

 

Reverse osmosis

 

In the reverse osmosis desalination process, only water molecules and a small number of ions can pass through the reverse osmosis membrane, and other ions and impurities will be trapped and concentrated with the reduction of water. This method is very energy efficient because there is no phase change. The pore size of the reverse osmosis membrane is < 10×10-10 m, and it can filter out various bacteria, viruses, heat sources and other pollutants at the same time to obtain high-quality pure water. Low production costs with low salt and other impurities.
