The rising issue of water scarcity in coastal communities and island nations is addressed with the utilization of sweater desalination plants. In fact, the desalination process is considered by many experts as the future for potable or drinking water production.

To meet the demands of fresh water supply, countries such as Saudi Arabia use desalination plants. Since the seawater has high salinity and TDS, it requires a series of filtration processes and the use of seawater membranes with RO technique enables to achieve highest salt rejection resulting in the production of purified water.

At Dutco Tennant LLC, we supply high-quality Seawater Composite Reverse Osmosis Membranes that help in meeting the requirements of desalination plants. This innovative product will also be exhibited at WETEX 2022 which will begin from 27th September ‘22 to 29th September ‘22. Make sure to visit us at Stall no. 6B 20 as our expert representatives will be present to offer live demo, insightful interactions and more.

But before you plan to arrive at the exhibit, here are some key benefits to know about the seawater desalination method using RO technique. Keep reading till the end to find out.

Basics of Seawater Reverse Osmosis (SWRO)

The ultimate goal of the desalination process is to eliminate the presence of salt in seawater which is concentrated at about 3-3.5%. The salinity and TDS of seawater are the key impurities that make them unsuitable for drinking. Aside from these, there are other constituents as well that are needed to be handled such as silica, color and microorganisms.

In order to achieve this goal, the process starts with drawing seawater via an intake pump from an intake pipe submerged on the seafloor or from a beach well. This drawn water is transferred to the  equalization tank or basin. From this process onwards, the seawater goes through pretreatment. Usually, the pretreatment comprises one or multiple filtration units that work to remove particles that are larger than 1 nanometer. This series of filtration plays a key role in reducing the risk of RO membrane fouling.

Obvious Benefits of Using RO Seawater Desalination

Modular Systems

The desalination plants are mostly constructed with modular system design. Therefore, making the system to be compact and easy to install. They are also easy to move resulting in reduced capital costs. Such modular systems fit perfectly for commercial or municipal drinking water applications where space is limited but have the requirement for increased water supply.

Highly Purified Water

The reverse osmosis technology makes the water so pure that it requires additional inclusion of minerals back into the water. The process eliminates some of the essential minerals that the humans require along with the taste that we are familiar with. Hence, the remineralization process needs to be applied to compensate for this and also regulate the pH level.

Greater Yield

Currently, the only used desalination treatment is of the thermal variety. It functions similarly as the water cycle process. This approach works really well in eliminating unwanted particles, however, collection and evaporation of steam is inefficient and results in lower yield production of pure water in comparison to RO technique. Hence, the RO desalination process operates with greater yield.
