摘要： Increased control and efficiency over the wastewater purification can be achieved through creating conditions that allow the operator to selectively prioritize the digestive function of microorganism in the activated sludge. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is passed through an atomizer or a cavitation pump to instantly render the reactive gas to an ultra-fine bubble state. At least a portion of the ultra-fine bubbles dissolve within the gas-dispersion return sludge, activating the dormant microorganisms. Due to a complete or an almost complete absence of biodegradable material in the gas-dispersion return sludge, the microorganism prioritize their digestive function, and when exposed to biodegradable pollutants present in wastewater, digest the pollutants using biochemical pathways different from the ones used in nature.

摘要： A fluid decontamination and apparatus and a method of fluid decontamination, introducing, via an inlet nozzle, a contaminated fluid from a fluid source into a continuous pipe section. The inlet nozzle is coupled to the continuous pipe section that enables fluid flow therethrough. Hydrodynamic cavitation is generated upon exiting the inlet nozzle within the continuous pipe section by spraying and evenly distributing the fluid that induces cavitation formation within the fluid across a three dimensionally open structured (3DOS) substrate disposed within the continuous pipe section. The 3DOS structure is positioned proximate to the inlet nozzle such that the hydrodynamic cavitation generated by the inlet nozzle enters the 3DOS substrate and the 3DOS substrate maintains the hydrodynamic cavitation of the fluid flow into the 3DOS substrate to enable destruction of toxic species and unwanted organic compounds contained in the contaminated fluid.

摘要： Systems and processes for purifying and concentrating a liquid feed stream are disclosed. In the systems, the concentrated liquid output from the high pressure side of a reverse osmosis stage is used as the draw solution in the low pressure side of the reverse osmosis stage in a configuration called osmotically assisted reverse osmosis. This reduces the osmotic pressure differential across the membrane, permitting high solute concentrations to be obtained, hastening the purification of the liquid. Reduced system pressures are also obtained by arranging multiple osmotically assisted reverse osmosis stages in a cross-current arrangement. Overall system energy consumption is reduced compared to conventional thermal processes for high concentration streams.

摘要： Apparatus for protecting submerged equipment from biogrowth. In one embodiment, a submerged, underwater ultrasonic transducer assembly is enclosed in an isolation chamber that contains a zone that is free of bio organisms. The isolating chamber encloses the transducer assembly to provide an outer surface exposed to the body of water where that outer surface is distanced sufficiently from the transducer assembly to ensure algae is inhibited from growing on the outer surface. The isolating chamber is a water-tight enclosure filled with a liquid. In another embodiment, the transducer assembly is surrounded by a light array that directs illumination toward the assembly. The illumination is at a wavelength that inhibits biogrowth. The light array includes a plurality of light strips with spaced apart lights. The light strips are supported by a bracket such that the transducer assembly is fully exposed to the illumination from the light strips.

摘要： The invention relates to a method for activation of concrete mixing water. The method includes preliminary action on the mixing water in continuous flow by pulsed high-voltage electrohydraulic discharges with supply DC voltage from 500 V to 5000 V at a pulse frequency from 2 Hz to 10,000 Hz and a current from 0.1 A to 10 A on electrodes of copper and/or iron and/or titanium. Then the water is treated in a mechanical and/or ultrasonic cavitator in the developed cavitation mode and at a water pressure from 0.8 atm to 6 atm without addition of plasticizers and/or surface-active agents.

The system includes a transparent solar dome with a peak point. The transparent solar dome is supported on a base that includes a bottom panel and sidewalls that form the outer perimeter of a freshwater basin. A saltwater basin is concentrically located within the freshwater basin, both of which may be square in shape. A first evaporation enhancement feature includes a plurality of reflectors for directing additional solar rays into the dome. A second evaporation enhancement feature includes an ultrasound generator centrally located on the bottom of the saltwater basin to atomize the saltwater in the saltwater basin. A third evaporation enhancement feature includes a plurality of copper structures extending from the peak of the solar dome to the perimeter of the freshwater basin.
