摘要： Granular calcium hypochlorite containing from about 0.001 to about 1.0 weight percent of finely-divided polyfluorinated polymer, e.g., polytetrafluoroethylene, dispersed throughout the granules is described. The product may be compressed and formed into shaped articles, e.g., tablets. The granules may be prepared by admixing the polyfluorinated polymer with particulate calcium hypochlorite, compacting the mixture and granulating the compacted product. Tablets prepared from the polyfluorinated polymer containing granular clacium hypochlorite dissolve in water at a rate slower than tablets prepared without the polyfluorinated polymer. Finely-divided calcium hypochlorite powder, e.g., powder of less than about 10 microns in size, is rendered more conveyable and compactible by the addition of the finely-divided polyfluorinated polymer; and mixtures of finely-divided calcium hypochlorite powder and particulate calcium hypochlorite is rendered more readily compactible.

摘要： An apparatus for dissolving a solid chemical material including a housing having a base and sidewalls that define a cavity within which is seated a container that is spaced from the housing sidewalls and covered with a grid is described. A flange connects the upper end of the housing sidewall to the container sidewall above the grid. A plurality of arrayed openings in the container sidewall above the grid and below the flange level leads to an annular collection zone in the housing. An outlet discharge pipe is connected to the collection zone and an inlet pipe for charging dissolving liquid communicates with the container below the grid.

摘要： A chemical feeder having a collection reservoir and an erosion reservoir located within and spaced from the wall of the collection reservoir. An elongated cylinder is supported on the collection reservoir and the lower end of the cylinder is located in the collection reservoir. The collection reservoir has a water discharge outlet and the erosion reservoir has a water inlet with a valve to control the flow rate of water into the erosion reservoir. A canister containing solid chemical sanitizing elements is supported in the cylinder and its lower portion is located in the upper portion of the erosion reservoir. Openings are located in the lower end portion of the canister so that solid dry chemical sanitizing elements located in the lower end portion of the canister can be contacted by water in the erosion reservoir to erode and dissolve the solid elements to chemically treat water flowing out of the erosion reservoir into the collection reservoir.

摘要： Described is particulate halogen-containing material, e.g., calcium hypochlorite, containing from about 0.1 to about 10 weight percent of colorant-treated particulate inorganic water soluble salt, e.g., sodium chloride. The colorant used with the sodium chloride salt is resistant to oxidation by the halogen specie in the material and is water dispersible. The amount of colorant used is from about 0.01 to about 5 weight percent, based on the inorganic salt. Preferred are the water dispersible phthalocyanine colorants.
