Abstract: A mixing chamber system for removal of contaminants from a liquid, and related systems and methods, are provided. The mixing chamber system includes a length of pipe having a hollow interior. A plurality of perforated discs are stationarily positioned within the hollow interior in at least a portion of the length of pipe, wherein each of the plurality of perforated discs has a curved profile, wherein a middle portion of each of the plurality of perforated discs is offset from a radial edge of each of the plurality of perforated discs, respectively.

Abstract: method and system for decomposing organic compounds in wastewater that uses an interaction between an acid, a permeable structure and ultra violet light to accelerate the decomposition of organic compounds in wastewater. This invention can be used to decomposing organic compounds in industrial process and wastewater discharges, municipal drinking water supplies, food processing rinse water and commercial and residential water purification systems.

Abstract: The present disclosure is drawn to a method for removing colloidal titanium dioxide and titanium oxychloride from by-product hydrochloric acid, typically without the use of metallic hydroxides and/or other neutralizing agents. Often, the decontaminated hydrochloric acid product is commercial grade and has concentrations greater than 85 wt % of the concentration of untreated by-product hydrochloric acid. The method includes adding phosphate ion source and quaternary amine or other precipitating agent to the by-product hydrochloric acid to cause the titanium dioxide and the titanium oxychloride to form a precipitate. In one embodiment, the method further includes heating at least one of the phosphate ion source, the quaternary amine or alternative precipitating agent, the by-product hydrochloric acid, or combination thereof. The precipitate can then be separated from the acid, thus producing a decontaminated hydrochloric acid product with reduced levels of titanium and other contaminants.

Abstract: A self-cleaning/self-purging ceramic, telflon-copolymer composite filter capable of continuous and/or intermittent cleaning and suitable for installation within a reaction or precipitation vessel. The filter can be cleaned either continuously or intermittently by ultra sound vibration and/or backpressure within the filter system. This invention is appropriate for use in industrial, pharmaceutical, commercial and municipal processing and/or wastewater treatment applications where the removal of undesired contaminants is desired.

Abstract: A method and system for the creation of large particle precipitates to facilitate the filtering of particles from a flow of water or other liquid that makes use of a venturi device for mixing, compressing and diffusing chemicals with the flow for treatment. This invention provides a quick, efficient and economical method of removing suspended or dissolved particles from a liquid media and does so without requiring complex expensive controls and equipment.

Abstract: A method of reclaiming used motor oil for further use is disclosed comprising (a) admixing used impurity laden motor oil with an effective amount of acetone as a flocculating agent and an effective amount of a second ketone as a wetting agent thereby forming an oil impurity flocculent mixture; (b) subjecting said mixture to a force such that a heavy phase and a light phase are formed, wherein said light phase is comprised of lean motor oil, acetone, and a second ketone, and wherein said heavy phase is comprised of flocculated impurities, any remaining acetone, and any remaining second ketone; and (c) separating said light phase containing said lean motor oil from said heavy phase containing said flocculated impurities. Preferably the second ketone is diisopropyl ketone, though other second ketones are also functional.

Abstract: A fluid valve that comprises a body forming a cavity and a cap on the body extending over the cavity, the cap and body carrying interengaging threads allowing rotary make-up of the cap on the body; a diaphragm in the cavity and seated on a ledge formed in the body, thereby to form a seal; a pressure-transmitting element in the cavity to transmit cap thrust to effectuate the seal; and blocking structure to block relative rotary movement between the pressure-transmitting element and the body.
