1000LPH RO Seawater Desalination System

What is a Seawater Desalination System?

Seawater Desalination is the production of fresh water by desalinating seawater.

It is an open-source incremental technology for realizing water resource utilization, which can increase the total amount of fresh water and is not affected by time, space and climate. It can ensure a stable water supply for drinking water for coastal residents and water replenishment for industrial boilers.

Why is Seawater Desalination becoming more and more popular?

As the shortage of water resources becomes more prominent, the development prospects of Seawater Desalination are broad.

The three common ways of obtaining fresh water in the world are groundwater extraction, remote water transfer and seawater (brackish water) desalination. As an important open source measure, groundwater extraction has small engineering volume and low cost, which is a very attractive advantage, but groundwater extraction is greatly restricted by resource conditions. In addition, due to excessive groundwater extraction for many years, underground funnels have been formed in many areas, causing houses to tilt and even causing environmental hazards such as seawater backflow. Groundwater extraction has been restricted.

What are the advantages of Seawater Desalination?

1. Reverse osmosis membrane is suitable for desalination of seawater and high-concentration brackish water. It has good desalination performance, high stability, and low operating and maintenance costs for membrane elements.
2. The water output is stable and high, and the number of membrane elements used can be reduced during system design, reducing equipment investment.

What is the main process of Seawater Desalination Equipment?

1: Raw water pump: The raw water pump provides pressure boosting guarantee for the sand filter, carbon filter and fine filter of the reverse osmosis pure water equipment. The water inlet pressure is stable and sufficient, which plays a role of pressure boosting. Ensure that the water pressure after pressure boosting is greater than the permeation resistance of the filter, carbon filter and fine filter, so that the water after pressure boosting can pass through the pretreatment system efficiently and provide sufficient water source for the RO system.

2: Quartz sand filter: The quartz sand filter is a pressure filter. It uses fine quartz sand filter materials of different specifications filled in the filter. When the inlet water flows through the filter layer from top to bottom, the suspended matter and viscose particles in the water are intercepted, thereby reducing the turbidity of the water.

3: Scale inhibitor: Prevent the reverse osmosis membrane element from scaling and clogging on the surface due to long-term operation

4: Reducing agent: Eliminate residual chlorine in the water entering the reverse osmosis membrane

5: Precision filter: Remove fine particles with a turbidity of more than 5 microns to meet the requirements of the subsequent process for inlet water

6: High-pressure pump: The high-pressure pump applies a pressure difference force to the water quality separation of the reverse osmosis RO membrane. In the separation of pure water and concentrated water, the micropores on the surface of the RO membrane are larger than the resistance of the pretreatment, so a high-pressure pump is required to apply high pressure to the pretreated water to penetrate the RO membrane.

7: Reverse osmosis membrane assembly:

The principle of reverse osmosis technology is to separate these substances and water under the action of a pressure higher than the osmotic pressure of the solution, based on the fact that other substances cannot pass through the semipermeable membrane. The membrane pore size of the reverse osmosis membrane is very small, so it can effectively remove dissolved salts, colloids, microorganisms, organic matter, etc. in the water.

8: Ultraviolet sterilization:

The purpose of disinfection is achieved by radiating microorganisms (bacteria, viruses, spores and other pathogens) and destroying the function of nucleic acids to kill microorganisms.
