Village Marine Tec.  is providing a full water production and treatment system for the STARSHIP.  We'll be installing two of their PW800 watermakers which will give us more than 1,500 gallons per day of total production capacity.

The system includes their new automatic freshwater flush system which inhibits bacteriological growth and allows us to store the unit for up to 10 days, a full media filtration package that increases the life of the cartridge filters and enables us to use the unit even under less than ideal feed water conditions, and a bromination system to disinfect and maintain our water tanks.  Village Marine is also supplying their remote control system that allows us to control all of the watermakers functions and monitor the water quality right from the pilot house.

Village Marine is located in Gardena, California and is the oldest and largest marine reverse osmosis manufacturer in the world.

This is the unit we are installing.  The entire package is only 54"x24"x16"

This is how it works:

Reverse osmosis has been derived from processes observed in nature.  Osmosis is a naturally occurring phenomena in which a membrane separates a pure solution from a concentrated solution.  The solutions have a natural tendency to mix because they have an inherent potential, called osmotic pressure.   The pure solution is drawn through the membrane seeking to equalize that potential.

In order to reverse this process (reverse osmosis) you must apply pressure exceeding the osmotic pressure of the concentrated solution.  In the case of sea water this is four hundred pounds per square inch.  At that pressure, osmosis stops.  Sea water reverse osmosis watermakers operate at eight hundred pounds per square inch.   Water flows over the surface of the membrane at high pressure (800 psi) and about 20% of the water passes through the membrane and is recovered as potable water.

So, let's recap;  we squeeze the sea water which has about 35,000 parts per million of  total dissolved solids (mostly salt) over the surface of the RO membrane, about 20% of the water passes through the membrane (we call this product water).  The product water has between 100 - 500 parts per million of total dissolved solids (again mostly salt) and is comparable in taste and quality to store bought bottled water.
