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.
