Large Capacity Seawater Desalination Plant Salt Water Purification Machine
Description of Seawater Desalination RO System
There are high salt content and high hardness in the seawater. So it is highly corrosive to the equipment. Moreover, during the seasonal changes, different water temperature will make reverse osmosis seawater desalination systems much more complex than conventional brackish water desalination systems. So the project investment and energy consumption are much higher.
Therefore, through careful process design and reasonable equipment configuration to reduce project investment and energy consumption, thereby reducing unit water production costs and ensuring the stable operation of the system is particularly important. So this type of Water Desalination Plants is very helpful.
How Does a Desalination System Work?
Seawater desalination equipment mainly adopts the permeation concept of reverse osmosis membrane. Using the principle of permeation, the reverse osmosis membrane filters the salt in the seawater except the concentrated water, leaving clean drinking water. As the pipeline flows out, the next step is processed. This process becomes osmotic pressure, proper water supply pressure, to remove impurities and salts from the water, leaving clean water for the purpose of reverse osmosis desalination.
Working Process of Seawater Desalination RO System
Pre-treatment System & RO System
The pretreatment system includes water supply pump, multi-media filter, precision filter and security filter, which mainly deals with large impurities, residual chlorine and fine particles contained in the raw water to ensure the water quality of the reverse osmosis system.
The reverse osmosis system includes high pressure pump, RO reverse osmosis membrane assembly, pressure regulating valve and cleaning box, which mainly further processes the pre-treated raw water into fresh water.
Reverse osmosis membrane element
It is mainly responsible for removing soluble salts, colloids, organic matter and microorganisms in water. It can remove more than 97% of ions in water, and can also effectively remove TOC and endotoxin, with a TOC removal rate of 90%.
