Desalination of saltwater is the process of removing salt and other pollutants to create fresh water.
Reverse osmosis is the method used in our desalination plants, the majority of the large and minute particles are removed by pre-treatment filtration before seawater is pumped from the ocean into the different types of desalination plants.
The osmosis process that ordinarily occurs in nature is then reversed by pressing the filtered seawater against specific membranes.
Salt, bacteria, viruses, and other pollutants are separated from the ocean by the membranes’ minuscule pores, in essence, they function as tiny strainers.
The amount of seawater that enters the facility and is converted to fresh drinking water is about fifty percent.
Diffusers are used to return the salt and other pollutants that have been extracted from seawater to the ocean, ensuring that they swiftly mix and do not harm the marine ecosystem.
What is the process of desalination?
The process of eliminating dissolved salts from water, including saltwater, brackish water,
Municipal wastewater, and even groundwater with a high mineral concentration, is known as desalination, this process is also known as desalting.
The end result of this treatment is water that is suitable for human consumption, as well as irrigation and various industrial uses.
As the processes involved in industrial desalination can be quite pricey at times, this method is only beneficial in circumstances, and there are many types of desalination plants.
Why is desalination important?
There is an increasing need for potable water as a direct result of the consistently rising global population.
Rainfall and subsurface water supplies, both of which are limited, are the only sources of water for arid regions, which have no access to freshwater.
The continued extraction of water from underground sources causes the water to become increasingly salty, which makes desalination an ever more important process as more people look for freshwater.
It is believed that thirty percent of the irrigated land throughout the world has problems with salt, and the only way to fix the problem is through expensive remediation.
Due to this, desalination can be used to create water that can assist in the maintenance of a variety of populations and provide a solution to a number of issues.
Types of desalination plants:
- Reverse osmosis desalination.
The process of desalination by reverse osmosis involves drawing water from the ocean and subjecting it to a first treatment that removes contaminants such as oil, seaweed, garbage, and so on.
The process of reverse osmosis can be carried out on the saltwater once it has been purified of organic contaminants.
Following the filtration process, we are left with two streams: one is saltwater, and the other is freshwater.
Before being poured back into the ocean, the brine solution is diluted in order to prevent significant amounts of salt from being released, which would be detrimental to the ecosystem.
After going through a process of remineralization and chlorination, the freshwater is then kept in tanks before being delivered to the distribution network so that it can be used.
Advantages of desalination:
- They make drinking water more accessible.
- They contribute to habitat preservation.
- They supply irrigation for the agriculture business.
Types of water used in desalination:
- Sea water.
The water that needs to be desalinated can come either from the surface of the sea or from deeper within the ocean.
In situations when there is a requirement to have as little of an effect as possible on the surrounding region, it is a valid option to source salty surface water.
This method is successful provided that filters can be utilised to reduce the quantity of pre-treatment that is required before the water can be processed by the primary treatment systems.
Although subsurface input is less harmful to marine life, it can be detrimental to freshwater aquifers in the area if the geology is not favourable.
Infiltration galleries, vertical beach wells, and radial wells are the three main types of wells used for extracting water from below the surface.
- Brackish water.
The saltiness of brackish water is far lower than that of seawater, and it is typically located in aquifers, which are underground reservoirs of water, or estuaries, which are lower courses at the point where a river empties into the ocean.
