Drinking water with sea water desalination systems - SWRO Stationary Sea Water Desalination Equipment for Residential & Commercial applications.

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.
