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 system. The AWECS forms a floating articulated barge having an onboard desalination system including reverse osmosis membranes. The filtration system is a sand filter residing on a damping plate submerged in the salt water body and filters the adjacent salt water for providing filtered salt water to the onboard desalination system. Wave action on the articulated barge provides energy to pump and pressurize the filtered salt water from the sand filter to the reverse osmosis membranes to produce potable water. The wave action on the articulated barge effects shaking of the reverse osmosis membranes, thereby rendering them self-cleaning. The potable water can be used for various applications, e.g., bottling, replenishing aquifers, ground and/or aquifer remediation, irrigation, etc.

Abstract: Systems and methods for processing produced water containing organic compounds include a processing vessel; a filtration layer including a filtration material; and a cleaning system that provides a washing solution to the filtration material during a cleaning cycle. The filtration layer is configured such that at least a portion of produced water that enters the processing vessel during a processing cycle of the processing system passes through the filtration layer before leaving the processing vessel. The filtration material is a metal compound such as a metal hydroxide or a metal oxohydroxide that is substantially insoluble in aqueous solution. The washing solution includes a reagent capable of reducing the metal compound to a reduced compound soluble in aqueous solution while not decomposing the organic compounds. The organic compounds such as crude oil may be recovered from the filtration layer material after the cleaning cycle, and the filtration layer may be regenerated.

Abstract: A device, method, and processor-readable medium for water quality detection and diversion are disclosed. Water entering a building's plumbing system is tested for impurities before it routes for consumption. Impurities in the water could include bacteria, viruses, chemicals, toxins, fertilizers, minerals, biological weapons, radioactive materials, and radioactive waste. Sensors are located throughout the device to check for impurities in the water as it travels through the building's plumbing. Certain sensors decide how to route the water through various treatments within the device. Treatments to the impure water could include multi-level filtration and heating/cooling cycles for a prescribed time period to reduce impurities below an EPA-approved threshold. If the water still retains impurities after treatment in the device, the device can decide to divert the water out of the building to prevent consumption and illness to building occupants.
