There are significant differences in the equipment used for removing most of the dissolved solids from seawater and from most surface or well waters. Seawater units are referred to as desalinators and surface/well water units are called reverse osmosis (RO) units. The laws of physics require approximately 1 psi driving force for each 100 mg/l of solids dissolved in the water to be treated. Seawater has about 35,000 mg/l of dissolved solids so to obtain the first drop of permeate water a pressure of 350 psi is required.
Reverse osmosis units on the other hand normally treat water where the dissolved solids content is in the area of 6,000 mg/l or less. The required pressure for that first drop of water for 6,000 mg/l is 60 psi. To insure an adequate flow of water from the respective devices seawater units usually operate in the area of 1,000 psi and RO units in a range of 150 to 250 psi. This additional pressure requirement for seawater increases the required strength of almost all components and requires much larger pumps. Also, seawater is extremely corrosive so the materials of construction for seawater units must be non-corrosive. All of these differences cause the cost of seawater units to be much higher than the cost of an equivalent gallon output RO unit.

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 range of sizes including 600gpd, 1,200gpd, 1,800gpd, and 2,200gpd seawater desalination systems.
Computer 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.
