Well water desalination plant design and supply

The concept of well water desalination

Well water desalination can be defined as the process of removing dissolved salts in the water to become water suitable for drinking, irrigation, or industrial uses, as 97% of the water on the earth’s surface is saline and not potable, and the desalination process has become an integral part of management strategies. Water in all countries around the world, where more than 75 million cubic meters are desalinated per day, is enough to cover the water needs of 300 million people.

Carewater design, supply, and installation of a well water desalination plant for Dunkin’ Donuts

There are food factories and restaurants in the Kingdom that need to use desalinated water on a daily basis. You can read more about water treatment in food factories from this article. In Water Care, we are proud to design, supply, and install a water desalination plant with a production capacity of 5 cubic meters per day at Dunkin Donuts.

Technical specifications that must be taken care of when designing a well water desalination plant

Equipment manufacturing country

One of the most important specifications that must be taken care of, as the country of manufacture of each equipment differs in terms of quality and availability of spare parts.

Accurately define specifications

The type of electricity used for each piece of equipment, the materials manufactured, for example, stainless steel, is better because it is not exposed to rust. The type of equipment is horizontal or vertical so that it matches the place in which it is placed.

Machine control type

The equipment varies in terms of the type of control between manual and automatic, and it is necessary from the outset to determine the most appropriate for the needs of the place.

The material of the equipment

Be careful with the material for making the pipes, as PVC is the best because it does not rust and does not react with water or chemicals used during treatment.

Types of Equipment in Well Desalination Plant

  • Raw water feed churn.
  • High-pressure pump.
  • Reverse osmosis membranes.
  • pH adjustment unit.
  • Pipes, connections, and electrical panel.
  • Measuring devices.

Important requirements that must be met in raw water before treatment

  • Iron content in raw water is less than 0.05 mg/L.
  • The raw water silt ratio (SDI) is not more than 3.
  • The water should be free of (H2S) and chlorine.
  • The plant feedwater temperature is not more than 25°C.

Stages of water treatment

First: primary treatment.

Second: the main treatment.

Third: secondary treatment.
