Abstract: A medical imaging system for detecting ionizing radiation. The system includes one or more pixilated imagers positioned to acquire patient image data and one or more position sensors positioned to acquire patient position data. Once the patient image data and patient position data are acquired, one or more processors operably connected to each of the one or more pixilated imagers and one or more position sensors calculate a three-dimensional mass distribution based on patient image data and patient position data.

Abstract: Bauxite mineral is used directly, to remove phosphates from water, in a high efficiency, highly economical system. The process of the invention involves the step of contacting the waste water stream with Bauxite for a time sufficient to lower the phosphate concentration to a predetermined lower level. The predetermined lower level is typically less than about 2 mg/l of water, and can be to a concentration of less than 1 mg/l. The Bauxite has an average particle size of greater than about 50 mesh. Advantageously, the particle size is at least about one quarter of an inch.The Bauxite which is used can be washed and graded to produce Bauxite having a particle size on the order of about one quarter of an inch. The Bauxite can be ground to an average particle size of at least about 50 mesh to produce a material having a higher reaction rate.

Abstract: A process is disclosed for treating food wastewaters by acidifying to a low pH, adding an alginate, and, preferably, adding lime to a pH of at least 7.0, without adding iron or aluminum to assist in coagulation and flocculation of the wastewater. A floc is formed at acid pH in some wastewaters and at neutral to alkaline pH in other wastewaters treated with lime. After recovery of the floc as a sludge, the process provides at least about 70% removals of Total Suspended Solids (TSS), Biochemical Oxygen Demand (BOD), and Chemical Oxygen Demand (COD) at reasonable costs and with negligible formation of free fatty acids in the resulting sludge.

Abstract: A process is described for treating a feed wastewater from a food preparation plant to recover substantially all of its fats and up to 50% of its proteins in a chemical float sludge which is selectively admixed with an absorptive bulking agent, such as sawdust, at a dry-basis weight ratio of 3-4 pounds of bulking agent to one pound of total sludge solids to produce a biomass mixture which is selectively dried and regulated in size to a maximum of 1/8-inch to produce a biomass fuel, characterized by a fuel value of approximately 11,000 Btu per pound, which is highly suitable for self-sustained burning in a gasifier-type suspension burner. After removal of the float sludge, the partially purified wastewater is aerobically treated with microorganisms to produce activated sludge, a selected portion thereof being recycled to the feed wastewater before admixing coagulation and flocculation chemicals therewith.

Abstract: A process is described for producing an animal feed, comparable to feathermeal in properties and appearance, from two waste products: float sludge and activated sludge. The process uses a bulking agent for extracting excess fat from the sludges, particularly the float sludge, while a mixture of the sludges and the bulking agent is being stirred, heated, and dried. Blood, chicken litter, meat scrap, and the like can be substituted for activated sludge to provide protein. The bulking agent can be any material that can expose the sludges to air, that is capable of absorbing fat, and that can be separated from the dried and partially de-fatted sludges. Wood chips are the preferred bulking agent. Wood shavings, shredded cardboard, shredded newspaper, paunch manure, and the like can be substituted for wood chips as the bulking agent.
