250LPH Desalination Plant
There is high salt content and high hardness in the seawater, and it is highly corrosive to the equipment. Moreover, during the seasonal changes, different water temperature will make reverse osmosis seawater desalination systems much more complex than conventional brackish water desalination systems where the project investment and energy consumption are much higher.

250 LPH Seawater Desalination Plant
The Puritech 250 LPH Seawater Desalination Plant is an industrial RO system engineered for high-TDS feed water (up to 35,000 ppm), making it ideal for seawater or very saline brackish water. Moreover, it delivers about 250 liters per hour of permeate, using a robust design that’s built to handle corrosive environments and ensure consistent production. Because the recovery rate is 35%, it balances efficiency with durability.
Key Features & Benefits
- High Salt Tolerance: Handles seawater feed up to 35,000 ppm TDS, so you can treat marine or coastal water sources.
- Reliable Recovery Rate: At 35%, it provides a good balance between output and reject minimization.
- Stainless Steel Frame (SS304): Built with corrosion-resistant materials to endure salt and harsh conditions.
- Dual Sea Water RO Membranes: Uses 2 × Vontron SW21-4040 SW membranes to deliver high rejection of salts.
- Comprehensive Pre-Filtration: Sand filter + micron/particle filters protect the membranes and extend life.
- Automatic Control Panel: Includes flow meters, pressure gauges, and standard connections for feed, permeate, concentrate, and flush functions.

Applications
This desalination plant is suitable for:
- Coastal communities need fresh water from seawater.
- Industrial sites requiring high-TDS water treatment.
- Remote or island locations where feed water is saline.
- Agricultural and aquaculture uses where seawater or brackish water is available.
Usage Notes
- Ensure feed water quality testing before installation: check TDS, salinity, turbidity, chlorine, etc., to avoid damage to components.
- Because seawater is corrosive, regular maintenance is essential—especially for pre-filters and membranes.
- Electrical supply must match 220 V / 60 Hz as per pump spec.
- Allow adequate space for flush connections and concentrate discharge.
