    摘要： Continuous breakpoint halogenation with hydroxyl free radical species is used to increase the rate of sanitization a water system and maintain a high rate of oxidation in the bulk water of the pool, spas, and other water systems despite the presence of accumulated demand. Undesirable compounds can be eliminated by maintaining a level of desired oxidation potential. The feedrate and ratio of halogen donor and free radical species can be optimized to sustain the desired ppm range of halogen and sustain an ORP of, for example, 780 mV-820 mV. Sustaining these parameters can prevent or even reverse the accumulation of combined halogen and other halogenated volatile compounds, which can contaminate the air and water of water facilities such as indoor swimming pools.

    摘要： A diffuser assembly for diffusing a fluid from a fluid source into a medium to aerate the medium. The diffuser assembly including a diffuser body in fluid communication with the fluid source and a membrane connected to the diffuser body. The membrane is circular and includes a slitting pattern divided into a series of similar angular segments. The segments are positioned adjacent each other in a circular arrangement to substantially cover the membrane. Each segment includes a plurality of rows each having a plurality of slits. The slits within the segment are arranged in a parallelogram pattern. A first line extending between adjacent slits in a common row is substantially the same length as a second line extending between adjacent slits in adjacent rows.

    摘要： A method and apparatus for treating wastewater streams by adding, either separately or as a mixture, a nitrate containing compound and an alkaline material in an amount sufficient to achieve a lower concentration of atmospheric hydrogen sulfide and dissolved sulfides downstream of the addition as compared to the atmospheric hydrogen sulfide and dissolved sulfides present in the wastewater stream prior to the addition. By adding alkaline material in addition to a nitrate containing compounds, the amount of nitrate containing compound added can be reduced by at least 10% as compared to the amount of nitrate that would theoretically need to be added in the absence of alkaline material to achieve a comparable lower concentration of atmospheric hydrogen sulfide and dissolved sulfides in the wastewater stream.
