摘要： A system for producing particles of aluminum chlorohydrate includes a feed stream configured to have a liquid solution of aluminum chloride, a conveyor belt having a surface configured to hold the liquid solution, a first radiant heat source configured to heat the liquid solution on the surface in order to form solid aluminum chloride hexahydrate, a grinder configured to crush the solid aluminum chloride hexahydrate in order to reduce an overall particle size of the aluminum chloride hexahydrate, and a second radiant heat source configured to heat the aluminum chloride hexahydrate in order to decompose the aluminum chloride hexahydrate and produce the particles of aluminum chlorohydrate. Methods of producing particles of aluminum chlorohydrate are also disclosed.

摘要： Methods are described for manufacturing ultra-low chloride, polyaluminum sulfate (PAS) coagulants useful for removing suspended colloidal matter and organic carbon in potable water, industrial process water and wastewater. A method of preparing a PAS solution includes forming a basic solution of sodium carbonate and sodium aluminate, adding an aqueous solution of aluminum sulfate and the basic solution to water to form a mixture having a pH between about 5 to 7, allowing precipitates of aluminum hydroxide to form in the mixture, and adding an additional aqueous solution of aluminum sulfate in an amount sufficient to dissolve the precipitates of the aluminum hydroxide and to form the PAS solution. The PAS solution has reduced corrosivity compared to other aluminum-based coagulants, and is particularly suitable for drinking water applications. The simplified methods used to produce the PAS coagulant provide a high quality product that is less expensive to produce than current methods.

摘要： A process for producing a polyaluminum chlorosulfate (PACS) includes adding an aluminum hydroxychloride (AHC) solution having about 38-43% basicity with (1) aqueous aluminum sulfate to form a solution and mixing a solid AHC with the solution to form an aqueous milky suspension or (2) a solid AHC and solid aluminum sulfate and adding water to the solid mixture to form an aqueous milky suspension, and maintaining the milky suspension for a period sufficient to allow the milky suspension to form a clear to slightly turbid solution including the PACS, the PACS having a basicity of 55 to 75%, the average molecular weight of the PACS is greater than or equal to 95 and less than or equal to 111, and salts present in the PACS comprise 0-1.0% sodium chloride by weight and 0-1.0% sodium sulfate by weight.

摘要： Aluminum chlorohydrate products include particles of aluminum chlorohydrate, in fractured crystal form, the particles having a basicity in the range of about 50% to about 85.6%, a bulk density of 40 to 65 pounds per cubic foot, and a mean particle size in the range of about 10 microns to about 15 microns. The particles may also have a surface area to weight ratio of about 295 to about 705 m2/kg, inclusive of both endpoints and all numerical values therebetween, where the ratio is measured by laser diffraction. Methods of producing such products are also disclosed.

摘要： A system and method for producing commercial strength solutions of aluminum chlorohydrate are provided. The method includes providing aluminum chlorohydrate monohydrate (ACHMH) powder, heating water to at least 120° F. and less than 200° F., and dissolving at least a portion of the ACHMH powder into the heated water to form the solution of aluminum chlorohydrate. The produced solution of aluminum chlorohydrate from the ACHMH powder has an aluminum oxide concentration ranging from about 18 wt % to about 27 wt %, has a basicity ranging from greater than 74% and less than 83%, and has a freezing point ranging from about 10° F. to about 16° F. The solution may also have an iron content of between about 0 to about 70 ppm as Fe.
