Modular sand filtration—anchor system and wave energy water desalination system incorporating the same

A system for producing potable water comprising:

• (a) an articulated barge system for floating on a body of salt water having waves, the barge system including a desalination system to produce potable water from filtered salt water, the barge system being arranged for converting energy of the waves into energy to pump the filtered salt water to the desalination system, the desalination system including a reverse osmosis membrane, the reverse osmosis membrane being arranged to be self-cleaned by the action of the waves on the barge system;
• and
• (b) at least one filter-anchor, the at least one filter-anchor being arranged for placement on the floor of the body of salt water and comprising a filter housing and a filter, the filter housing having an interior chamber, at least one inlet, at least one outlet, and a filter located within the filter housing, the at least one inlet being arranged for providing salt water to the filter, the filter being adapted to filter the salt water to produce filtered salt water, the outlet being coupled to the desalination system, whereupon the salt water can be drawn into the filter and filtered to produce the filtered water which can be pumped from the outlet to the desalination system by the energy of the waves, said filter housing comprising a barge structure that permits said filter housing to be towed to a sea water location.
