5 m³/day Water Desalination Plant
Safe fresh water is no longer a luxury but an essential element for the continuity of residential, agricultural and industrial projects alike. When you have a fixed, defined daily water need, a water desalination plant with a capacity of 5 m³/day becomes a practical and economical option, especially if the water source is low-salinity wells or the municipal network.
This size serves medium-sized farms, light industrial workshops, small residential buildings, and service facilities such as clinics and private schools. Since the technology used is reverse osmosis (RO), the quality is predictable and consistent, with operating costs that are easy to control.

Components of the 5 m³/day Water Desalination Plant
| No. | Item | Function |
| 1 | 1 × primary water tank, 1000 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, anti-scalant, etc.) |
| 3 | 1 × flow switch for feed pump cut-off | Automatically cuts off the feed pump when the water supply is interrupted or the pressure drops below the permitted limit |
| 4 | 1 × Italian chlorine dosing pump | Injects chlorine solution to disinfect the raw water, kill bacteria and algae, and protect the filters and membranes from biological contamination |
| 5 | 1 × chlorine dosing tank | Stores the chlorine solution to be drawn by the pump |
| 6 | 1 × sand filter 13*54 inch | Removes suspended impurities such as sand, silt and coarse organic matter |
| 7 | 1 × carbon filter 13*54 inch | Removes free chlorine, organic matter, odors and unwanted taste from the water |
| 8 | 1 × Italian anti-scalant dosing pump | Injects anti-scalant solution before the water enters the membranes to prevent the formation of scale |
| 9 | 1 × anti-scalant dosing tank. Function: stores chlorine solution | Stores the anti-scalant solution to be drawn by the pump |
| 10 | 1 × 20-inch micron filter | Removes fine impurities larger than 5 microns in diameter after the sand and carbon filters |
| 11 | 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 |
| 12 | 1 × 4-inch American membrane | Removes dissolved salts, heavy metals, chemicals and bacteria from the water |
| 13 | 1 × 4-inch pressure vessel (housing) | Tubes that house the membranes and withstand the high water pressure |
| 14 | 1 × operation and control panel | Controls the operation of the water desalination plant automatically |
| 15 | 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 |
| 16 | Interconnecting piping between the water desalination plant equipment | Conveys water between the stages of the water desalination plant |
| 17 | 2 × flow meters | Measures the water flow rate per second |
| 18 | 5 × pressure gauges | Measures the water pressure in the line it is installed on |
| 19 | 1 × low-pressure switch | Shuts off the pump when the pressure drops below the minimum limit |
| 20 | 1 × solenoid valve | Opens and closes the water flow in the line it is installed on |
| 21 | 1 × UV disinfection unit | Disinfects the product water and kills any remaining bacteria or viruses |
| 22 | 1 × final polyethylene tank, 1000 L | Stores the product water ready for use |
| 23 | 1 × Italian stainless steel final product pump | Draws the desalinated water from the tank |
| 24 | 1 × flow switch for final product pump cut-off | Automatically cuts off the pump when the water supply is interrupted |

Site Inspection for Installing the 5 m³/day Water Desalination Plant
A field inspection reduces the risk of an unsuitable design and includes:
- Testing fresh water samples and running a comprehensive analysis.
- Reviewing the available power source (electricity, available capacity, or solar power).
- Planning the water intake and brine discharge, and specifying the preparations required at the water desalination plant installation site.
- Verifying the installation space, ventilation, ease of access for maintenance work, and noise level.
The inspection helps fine-tune the selection of filters and pretreatment, and spares the client future scaling and clogging problems thanks to effective purification.
