Modular sand filtration-anchor system and wave energy water desalination system and methods of using potable water produced by wave energy desalination
A potable water producing system for disposition at a salt water body and methods of producing potable water are provided. The system includes a wave energy conversion system (AWECS) and a portable filtration-anchor system. The AWECS forms a floating articulated barge having a desalination system including a reverse osmosis membrane. The filtration-anchor system is submerged in the salt water body and includes a sand filter to filter the adjacent salt water for providing the filtered salt water to the desalination system on the articulated barge. Wave action on the articulated barge provides energy to pump the filtered salt water from the sand filter to the reverse osmosis member to produce potable water. The wave action on the articulated barge effects the shaking of the reverse osmosis filter, thereby rendering it self-cleaning. The potable water can be used for various applications, e.g., bottling, replenishing aquifers, ground and/or aquifer remediation, irrigation, etc.
1. A method of producing potable water for a desired application comprising:
(a) floating an articulated barge system on a body of salt water having waves, the barge system including a desalination system to produce potable water from filtered salt water and wherein at least one bi-directional pump is positioned between portions of the barge system that articulate based on wave motion to drive the at least one bi-directional pump in two alternating directions, the desalination system including a reverse osmosis membrane;
(b) disposing at least one filter-anchor on the floor of the body of salt water, the filter anchor comprises a filter housing and a filter, the filter housing having an interior chamber, at least one inlet, at least one outlet in fluid communication with said at least one bi-directional pump, and a filter located within the filter housing, the at least one inlet being arranged for providing salt water through the filter, the filter being adapted to filter the salt water to produce filtered salt water whenever the pump is energized by wave motion to pull salt water from said at least one inlet, through said filter and into said outlet;
(c) coupling the outlet to an input to a flow rectifier and coupling an output of said flow rectifier to the desalination system;
(d) utilizing the barge system to convert the energy of the waves into energy to pump the filtered salt water, moved in two alternating directions by said at least one bi-directional pump and rectified into a unidirectional filtered salt water flow by said flow rectifier to the desalination system, whereupon the filtered salt water is converted to potable water utilizing the reverse osmosis membrane, the reverse osmosis membrane being self-cleaned by the action of the waves on the barge system; and
(e) providing the potable water for use in the desired application.
