​Product Features 
Important: A separate seawater delivery pump is required to deliver seawater to the system at a minimum of 5gpm @ 30psi.
How It Works: Pressurized water from your seawater pump first enters the integrated sediment prefilter to provide extra membrane protection from dirt, sand, and debris. Additional pretreatment for excessive minerals or other contaminants may be needed to extend the life of the system. Prefiltered water then enters the desalination RO system to purify the water.

Purified water comes out of the RO system as a small stream, so a separate product water storage tank and repressuization pump is required to provide pressurized water to your taps. Purified water will begin filling the nearby product water storage tank until the included float switch shuts the entire system off. When there is a demand for water, the repressurization delivery pump is activated and draws water from the storage tank to your taps. If enough water is used to the point where the float switch is activated, the RO system will automatically turn on and begin replacing the water that has been depleted in the tank.

​How Much Water Does It Produce: We offer a 750gpd & 1500gpd Seawater Desalination System

Microprocessor Controller: Monitors several functional conditions and regulates operation of the high pressure pump and control valves. The controller is connected to sensors which, depending on their state, allow the cyclic production of purified water or prevent operation due to abnormal conditions. The standard configuration of the controller monitors feed water supply pressure for minimum level, product water storage tank level for system start/stop conditions and product water conductivity for maximum set point value and for digital front panel display. Additional optional parameters that the controller is capable of monitoring include main pump high pressure set point, low feed water tank level and membrane flush cycle occurrence and duration. Front panel buttons and digital display allow operator adjustment of set points and flush parameters. 

Automatic Membrane Flush: When the desalination system stops running, the residual water inside the membrane vessel will have a very high salt content, much higher than the feed water since it is concentrate or brine. If left this way that salt content will go through the membrane by osmosis so you will have salty water on the product side of the membrane. The patented PureFlush feature flushes the seawater purifying membranes with clean product water for several minutes after every shutdown protecting the membrane from high mineral build-up.

Salinity Monitoring: Automatic electronic monitoring. Temperature compensated with the digital continuous readout. The salinity monitoring components of the system provide TDS readout in ppm (parts per million) of product water. Salinity Range: Designed for seawater use up to 50,000PPM TDS (NaCl) (typical seawater salinity is 35,000 ppm).
​
Stainless Steel Frame: The RO frame is formed and welded of stainless steel - NOT ALUMINUM. The pump mounting supports are also stainless steel. The frame provides 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. 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. These reasons are why stainless steel is our only choice for sea water desalination systems.

Re: Price Increase Coming
Over the last six months we have seen a significant increase in the cost of materials, manufacturing, and transportation. Despite our efforts to maximize efficiencies, operational costs also trended up throughout much of 2020.
​As a result, RainDance Water Systems will be raising prices on our water treatment products effective May 1, 2021

 All Orders Including FREE Offers Placed Before May 1, 2021 Will Be Honored At Current Pricing.
