3 m³/day Water Desalination Plant

In many small projects and service facilities, large volumes of water are not necessary, but water quality remains a decisive factor that cannot be compromised. This is where a 3 m³/day water desalination plant comes in as an ideal solution that combines efficiency, simple operation and low cost.
This capacity is suitable for limited uses such as large homes, villas, small farms, clinics, laboratories and service offices, especially when relying on low-salinity wells or municipal mains water. Thanks to reverse osmosis (RO) technology, the 3 m³/day water desalination plant delivers water of consistent quality with economical consumption of energy and chemicals.

Components of the 3 m³/day Water Desalination Plant
| No. | Item | Function |
| 1 | 1 × primary water tank, 500 L | Stores the raw water ready for the treatment process |
| 2 | 1 × Italian stainless steel feed pump | Draws raw water and pushes it through the initial treatment stages (chlorine, filters, etc.) |
| 2 | 1 × Multimedia filter 10*54 inch | Removes free chlorine, organic matter, odors and unwanted taste from the water |
| 3 | 1 × Italian stainless steel high-pressure pump | Raises the water pressure to the level required to overcome the osmotic pressure and drive the water through the membranes |
| 4 | 1 × 4-inch American membrane | Removes dissolved salts, heavy metals, chemicals and bacteria from the water |
| 5 | 1 × 4-inch pressure vessel (housing) | Tubes that house the membranes and withstand the high water pressure |
| 6 | 1 × operation and control panel | Controls the operation of the water desalination plant automatically |
| 7 | 1 × plant support frame | The water desalination plant components are mounted on it to assemble them into a compact unit that is easy to transport and install |
| 8 | Interconnecting piping between the water desalination plant equipment | Conveys water between the stages of the water desalination plant |
| 9 | 2 × flow meters | Measures the water flow rate per second |
| 10 | 3 × pressure gauges | Measures the water pressure in the line it is installed on |
| 11 | 1 × low-pressure switch | Shuts off the pump when the pressure drops below the minimum limit |
| 12 | 1 × solenoid valve | Opens and closes the water flow in the line it is installed on |
| 13 | 1 × final polyethylene tank, 500 L | Stores the product water ready for use |
| 14 | 1 × Italian stainless steel final product pump | Draws the desalinated water from the tank |
