RainDance Water Systems Sea Water Desalination Systems 
Residential & Commercial Sea Water Filter 750gpd, 1500gpd, 2500gpd, 4000gpd 
Our SWRO sea water reverse osmosis systems are designed for commercial and residential applications where floor space is at a premium. All major system elements are mounted within a sturdy tubular stainless steel frame (NOT ALUMINUM), welded for long term rigidity, and open for easy access to all components. The TV systems are a compact, heavy duty sea water RO water purifier capable of producing up to 4000 GPD water production. Our smallest system, the TV-SWRO-750, is perfect for your water desalination needs anywhere from 10 gallons per day up to 750 gallons per day.  As with all of our purifier products, our TV-SWRO systems are fully equipped with the instruments and controls needed for reliable long term operation.
RainDance H2O SWRO-750 (750GPD)
sea water desalination reverse osmosis
750gpd Seawater System - Appearance will vary
Limited Time 750GPD RainDance H2O SWRO-750 Package Includes: 
  • 750GPD High Capacity Sea Water Reverse Osmosis Water Purification System
  • RO Membrane Pure-Flush – Helps extend membrane life. Clean water flushes the membrane upon start-up flush away any accumulated particles or debris.
  • Pretreatment – High capacity sand, sediment and dirt prefilter 
  • Separate External Water Alarm – Senses Leaks
  • MICROPROCESSOR CONTROLLER – The system PLC controls all major operating functions of the R.O. System including product TDS monitoring. The PLC controls the desalination system on/off from product tank level switch input and from feed water pressure fault. This on/off function controls the feed water solenoid valve and the main pump. A 5 minute flush of the membrane with product water is performed by the system controller on each tank full shutdown.
  • POWER ON/OFF SWITCH – The RO system is completely un-powered when this switch is in
    the OFF position.
  • LOW PRESSURE SWITCH – A pressure switch that shuts off the unit in the event of low pump pressure (filter outlet). This is used as a pump protection device. It is factory set to cut off if the pressure drops to 12 psi (0.8 bar). A minimum of 22 psi (1.5 bar) is required to originally start the RO. The unit does not automatically restart if the loss of water pressure was temporary due to some other water usage. 
  • PRESSURE RELIEF VALVE – A safety relief valve designed to protect the vessel(s) and
    system plumbing from an over-pressure condition. The 316SS valve is installed on the outlet of the fixed displacement pump and is factory set at about 975 psi (68 bar).
  • FRAME – The frame is formed and welded of stainless steel - NOT ALUMINUM. The pump mounting supports are also stainless steel. The frame provides a mounting for all the RO system components. Stainless steel is different from other steel alloys because it doesn’t corrode or rust. Therefore, stainless steel is used for many purposes like in buildings, monuments, automobile, machinery, and our seawater desalination systems, etc. Aluminum can dent, ding or scratch more easily as compared to steel. Stainless Steel is strong and less likely to warp, deform or bend underweight, force or heat.
  • LEVELING FEET ​– These allow for a stable mounting on an uneven surface. After adjustment
    of the feet, snug the looking nuts against the under side of the frame.
  • ​SWRO-750 Package Replacement Special Offer – RainDance H2O SWRO-750 Package will also include a *5 year replacement sediment filter package  Replacement Package Includes: 20 replacement sediment pre-filters. *5 year supply of sediment filters when replaced every 3 months

The Top 5 Questions asked about our sea water desalination systems:
  1. (Q) Can we drink the water after your system? (A) Yes, our desalination systems turn seawater to potable drinking water.
  2. (Q) Will your system pump water from the sea or salty well? (A) No, you will need to provide your own pump for the desalination system
  3. (Q) Do I need a separate storage tank? (A) Yes, The water produced by the desalination system comes out as a small stream, which is why you need a separate storage tank and a re-pressure pump to deliver the filtered water into your home, business, or other.
  4. (Q) Do you offer a desalination system that can accommodate custom power supply? (A) Yes, we have specific systems to accommodate power supplies for 1-phase or 3-phase and 220v 60hz or 220v 50hz.
  5.  (Q) How much do they cost? (A) Turning sea water into potable drinking water is not a cheap endeavor. Prices start around $12,000+ (USD). Contact our staff for a custom quote and current discounts!
