Abstract:
The present invention discloses a portable electrodialysis unit powered by photovoltaic panels for treating brackish/saline water and produce potable water for consumption. Potable water is important in water-scarce regions or circumstances, such as desert, drought, military operations, or natural disasters. The present invention provides a photovoltaic powered desalination system capable of dynamically changing salt removal rate and product water flow rate in order to fully utilize solar energy captured by the photovoltaic panels. The invention includes a direct electric current provided by one or more photovoltaic panels that charges batteries and provide an steady electric current to an electrodialysis desalinization unit and a control unit. The control unit communicates with the photovoltaic panels and electrodialysis unit, in conjunction with sensors to monitor water flow, conductivity, pressure, water elevation levels, and/or temperature, to create a closed loop feedback system. The closed feedback system allows battery charging, power regulation, and product water parameters to be controlled while maintaining efficiency.
Abstract:
Systems and methods can support an autonomous pool skimming system. The pool skimming system may have a body with two or more hulls. Two or more paddlewheels may be coupled to the body. An independent motor may drive each paddlewheel. The motors may be independently controllable to support steering. The pool skimming system may have one or more processing units, two or more distance sensors, one or more solar cells, and a power supply operable to power the processing units and the motors from energy supplied by the solar cells. One or more processing modules may configure the processing units to plan and execute a traversal path across the surface of a body of water, such as a swimming pool, to collect debris into a removable basket. A portion of the traversal path may be established according to signals from distance sensors.
Abstract:
A system and method for a point of use filtration system with backwash is provided. The system includes a first filtration element, a tank, and a second filtration element positioned downstream from the tank. A first and second valve are each positioned downstream from the first filtration element. A first control line is coupled to a first control switch or a first permeate line and the first valve, and a second control line is coupled to the second control switch or a second permeate line and the second valve. When the point of use demands permeate water, the first and second pressure drops cause the first and second valves to open so water from the tank flows in a reverse direction to backwash the first filtration element and exit through the first and second valves to the drain, while water from the tank simultaneously flows through the second filtration element to the point of use.

A portable system for treatment of liquids, gases, or both using precise energy separation (PES) is described herein. The system includes a power generation component which charges one or more energy storage units and powers the PES component of the portable system. The PES component includes one or more energy of dissociation sources and the energy storage units power the sources to provide an effective amount, intensity, and frequency of a promoter energy to specifically dissociate one or more target bonds of the target molecule present in contaminated liquids, gases, or both. Optionally, the energy stored in the system can act as a supplementary or back up power source.

Abstract:
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.
