Description

The desalination of salt water has become a preoccupation for the countries of the world due to the decrease and lack of water sources and pollution of water in the wells, in addition to the increase in salinity due to the lack of rain water in general.

Several institutions, ministries, and governmental departments concerned with desalination, such as the Ministry of Environment, Water, and Agriculture, the Ministry of Water and Electricity, and the General Organization for Saline Water Desalination, are conducting studies to find solutions to these problems and converting polluted and salty water to fresh water, where research is presented on the causes of water pollution, desalination methods, and water treatment Contaminated in wells and surface water.

In the Kingdom of Saudi Arabia, the Ministry of Water, the Saudi Ministry of Water and Electricity, the General Organization for Water Desalination and the National Water Company in cooperation with the Electricity Company have studied the causes of water pollution and methods of desalination of surface and groundwater and the establishment of many desalination plants in Saudi Arabia, so desalination stations in Saudi Arabia have become a basic necessity. In all cities.

On the other hand, the General Authority for Saline Water Desalination in Jeddah has established seawater desalination plants, and thus seawater desalination in Saudi Arabia will be the main tributary of other government projects with the aim of covering the continuous need for water in the Kingdom, while private sector companies and institutions have provided desalination plants as a solution Essential for water treatment, the Ramdoun Group has advanced as a leader in the water business since 1986 and has many projects in various countries of the world, providing basic and final solutions for water desalination, wastewater treatment, gray water and water recycling.

In view of the high demand for wells desalination plants, we will present to you in this topic a brief study of the mechanism of work of these wells.

The desalination plant consists of several stages, starting with:

Initial treatment and filtering.

Chemotherapy.

Osmotic pressure to reduce salts.

Final sterilization.

We will explain each stage separately:

First: treatment and initial filtering

It is carried out through sand filters containing media (gravel, sand, resin, and activated charcoal) and microscopic filters contained within a steel frame or made of fiber.

Second: chemotherapy

And it is done by injecting basic chemicals linked to the quality of the raw materials such as (sedimentation and concentrated sulfuric acid) with the aim of dismantling the solid chemical elements in the water and protecting the salt filters.

Third: osmotic pressure

The osmotic pressure mechanism filters the water as a result of the high pressure pump pressure on the salt filters, which leads to the isolation of the salts by up to 90%, which produces brine and potable water.

Fourth: Final sterilization

Sodium hypochlorite is injected to remove bacteria or by sterilization with UV radiation, or both.

In general, the amount of desalinated water produced is linked to several factors in which the quality of raw water is the main factor in addition to the quality of the membranes and the quality of the plant in general.
