Reverse osmosis mainly uses electricity as energy. It is a seawater desalination technology that uses semipermeable membranes for filtration and separation. The principle of reverse osmosis is that seawater passes through a high-pressure water pump and is pressurized. Finally, concentrated brine is discharged at the same time, and fresh water passes through a semipermeable membrane to achieve the effect of seawater desalination. It is suitable for use in high-quality fresh water such as drinking water and industrial water.
Reverse osmosis membrane is the main component of desalination equipment. Reverse osmosis membranes can be divided into two types: homogeneous membranes and asymmetric membranes. Conventional reverse osmosis (RO) membranes can be disinfected with conventional chemicals. Due to different usage requirements, high-temperature (85°C) sterilization membranes can be selected. Reverse osmosis membranes can intercept substances larger than 0.0001μm. Reverse osmosis is the most sophisticated membrane liquid separation technology. Reverse osmosis membranes are semipermeable membranes that only allow water molecules to pass through but not solutes. They can block all soluble salts and organic matter with a relative molecular mass greater than 100. The desalination rate of cellulose acetate reverse osmosis membranes is generally greater than 95%, and the desalination rate of reverse osmosis composite membranes is generally greater than 98%.
In addition, the biggest advantage of reverse osmosis is low energy consumption and high efficiency. The disadvantage is that the desalination rate is usually low. In addition, seawater needs to be pre-treated before entering the reverse osmosis system to prevent semi-permeable membrane pollution and clogging. Therefore, when choosing seawater desalination technology, it is necessary to make comprehensive considerations based on specific needs and conditions.
The Gulf region, especially the UAE and Saudi Arabia, has abundant oil and gas resources, sufficient energy and seawater resources, and is suitable for high-quality fresh water such as drinking water and industrial water. TrennTech‘s technical engineers and sales experts have been providing water resource treatment services to enterprises, residents and industrial users in the Gulf region.
