Small water desalination and purification plants have become a necessity in the modern age, especially in areas suffering from a shortage of fresh water sources. A water desalination and purification plant with a production capacity of 5000 liters per day is an ideal solution for limited uses such as large houses, small farms, or commercial establishments. In this article, we will discuss the details of the components of the desalination plant, its working mechanism, as well as the factors that determine its cost.
Components of a 5000-liter per day water desalination and purification plant.
The small water desalination and purification plant consists of several main components that work together to achieve the best water quality suitable for drinking or other uses.
1. Intake and Preliminary Treatment Unit:
- Suction Pump It works by drawing water from the source, whether it's a well, tank, or seawater.
- Sand Filter Removes large particles such as dust and sediments.
- Carbon filter: It removes organic materials and chlorine to improve water quality and protect the membranes.
- Micron filter: Removes small particles that may affect the efficiency of the membranes.
2. Reverse Osmosis System.
- High-Pressure Pump. Used to increase water pressure and enable it to pass through the reverse osmosis membrane.
- Semi-permeable membranes It is the main component that removes salts, heavy metals, and dissolved substances from the water.
- Salinity removal unit The salty water resulting from the purification process is discharged.
3. Final treatment unit.
- Acidity adjustment device It balances the acidity in the water to make it safe and suitable for drinking.
- Ultraviolet (UV) disinfection unit It is used to disinfect water and eliminate bacteria and viruses.
- Mineral addition It reintroduces essential minerals to improve the taste and quality of the water.
4. Produced water tank.
- A sealed storage tank made of rust and bacteria-resistant materials, designed to store purified water ready for use.
5. Control and monitoring panel.
- Digital display It displays operational data such as water pressure, salinity ratio (TDS), and flow rates.
- Sensors To monitor water quality and system efficiency.
6. Pipes and fittings.
- Pipes and fittings made of corrosion-resistant materials to withstand high pressure and ensure no water contamination during operation.
Mechanism of operation of the water desalination and purification plant.
A 5000-liter per day desalination plant works through integrated steps to convert raw water into pure water. These steps include:
- Water extraction from the source: Using a suction pump, the raw water is transferred to the plant.
- Primary treatment Large impurities such as sediments, chlorine, and organic materials are removed using different filters.
- Reverse osmosis desalination: The water is pressurized through reverse osmosis membranes that separate salts and contaminants from the water.
- Final treatment The water's pH is adjusted, essential minerals are added, and it is disinfected.
- Storage The purified water is stored in a sealed tank before being distributed for use.
Factors that affect the cost of a desalination plant
The cost of the station varies depending on the manufacturer and the availability of accompanying installation and maintenance services.
1. Type of raw water:
- The cost of the station varies depending on the type of water being treated; well water treatment differs from seawater treatment due to the salt concentration.
2. Component quality
- Prices vary depending on the quality of components used, such as membranes, pumps, and filters. High-quality components last longer and operate with higher efficiency.
3. 2. Plant design
- The design of the station and its technological advancement affect its cost. Stations that have smart control systems and advanced sensors are typically more expensive.
4. Storage tank capacity
- The capacity of the tank associated with the station affects the price. Larger tanks are more expensive.
5. Optional add-ons
- Such as ultraviolet (UV) disinfection units or mineral addition systems. These options add additional costs to the station.
6. Consumed energy
- Energy consumption efficiency is an important factor, as stations that consume less energy are considered more economical in the long term, even though they may have a higher initial cost.
7. Installation and maintenance services
- The cost of the station varies depending on the manufacturer and the availability of accompanying installation and maintenance services.
