Abstract:
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit, injects ozone into the portion to provide an ozonated portion, and recombines the ozonated portion with the flow of water in the conduit. Another method and system identifies a species-destructive reaction product of ozone with a water constituent, determines a life of the reaction product, and contacts ozone with a water containing the species for a period determined according to the determined life of the reaction product.
Abstract:
A detergent composition comprises clay, a surfactant system and a copolymer of N-vinylimidazole and N-vinylpyrrolidone. The copolymer is present in the detergent composition in an amount of 0.01% to 10.0% by weight. The copolymer has an average molecular weight of from 5,000 to 50,000 and a molar ratio of N-vinylimidazole to N-vinylpyrrolidone of from 1:1 to 1:02.
Abstract:
A method and system of ozone treatment diverts a portion of water from a flow of water in a conduit; injects an ozone-containing gas into the portion to provide an ozonated portion; recombines the ozonated portion with the flow of water in the conduit; and regulates the diverted portion to provide a minimum diverted portion flow rate according to flow in the conduit and proportion of ozone in the injected gas.
