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.

Quick Guide: How Our Whole House/Commercial Seawater Desalination Systems Work:

You will need to supply pressurized seawater to the system (pump for sea water to system not included). Sea water will enter the attached prefilter for extra membrane protection - additional pretreatment may be needed before this system. Prefiltered water then enters the seawater RO membrane water purification system. The purified desalinated water comes out as a small stream so a separate storage tank and repressure pump is needed to collect and deliver purified water to your taps or application. Once your storage tank fills with purified water the included float switch closes and shuts the entire system off. When there is a demand for water the repressure delivery pump is activated and draws desalinated water from the storage tank and to the open tap(s). If enough water is used to the point where the float switch is reopened, the TV-SWRO-750 Desalination system is automatically turned on to replace the product water that has been depleted.

Note: We can quote our compatible storage tanks and repressure pumps upon request or source your own and we will include the float and float switch to control the system by tank level free of charge.
