Seawater Desalination Can Meet Earth's Future Water Needs

Earth Day was celebrated recently, and a list of environmental issues were highlighted. One issue is water scarcity that can be resolved with seawater desalination.
MONTCLAIR, Calif. - April 27, 2020 - PRLog -- Water is the most basic need of humans, and it's becoming a scarcity. One solution humans have come up with is seawater desalination. This solution is something humans need to focus on if they want to keep their pledge of protecting the environment that was made recently on World Earth Day.
The term seawater desalination is not a new one for people who are aware of water treatment processes and especially those who come in contact with a marine watermaker equipment frequently.

The simplest definition of seawater desalination is that it's a water treatment technology that turns seawater into contamination-free, tasteless and odorless water to ensure its fit for human consumption. This technology is well appreciated across different parts of the world as it allows for a person or an entity to have a sustainable supply of water. This technology is a great solution for drought-hit cities and countries as it provides water instantly and can quench the water thirst of hundreds of thousands of people at once.

As the demand and installation of seawater desalination systems are increasing rapidly, it will reach a new high in 2030. In 2015, about 180,000 seawater desalination plants in the world, and they produced approximately 23,000 million gallons per day. This number will likely reach more than double by 2030.

Seawater desalination is particularly needed in the Middle East and North Africa, but it will soon be needed in the US, Latin America and even Asia. One of the reasons why all countries are adopting this technology is its weatherproof ability. It means that anyone who is living near the sea or even on the sea can use this technology to get thousands of gallons of water in a day and quench the needs of people, commercial establishments, ships, boats and large industries among others.

The process of separating water and salt is not an easy one. The use of semi-permeable reverse osmosis, also known as SWRO is essential. It is a more popular option that another desalination process, thermal evaporation.

Oceans have more than 97 percent of the water present on the planet. So, humans will need to turn to it when freshwater and even brackish water (a combination of freshwater and seawater) deplete. It is the only option humans will have for the next few decades when the demand for water for the ever-growing population rises.

The costs were a big concern when it came to adoption of desal plants and processes across the world. Hence, the focus is on reducing costs.
