Method and apparatus for treating animal waste and wastewater
InactiveUS20060060525A1Solid waste disposalWaste water treatment from animal husbandryEvaporationWastewater
Novel methods and apparatuses are disclosed for the treatment of wastewater to reduce, often associated, offensive odors. Irrigation of oxygenated liquid on top of a permeable cover effectively creates an aerobic treatment zone at the top of the lagoon whereby odorous gases being produced anaerobically below the cover are metabolized within this zone before being released to the atmosphere. This same system also serves to increase evaporation from the overall waste handling system therefore substantially reducing or eliminating the need for land application of treated wastewater.

Fine particle lint filter
A lint filter having a succession of mesh screens which are arranged in parallel in a tank which receives lint-containing water from a laundry facility. The mesh screens are positioned so that the lint-containing water must pass through the screens in order to leave the tank. The lint-containing water is sprayed evenly on one side of the tank and proceeds across the tank toward the mesh screens. The mesh screens are angled so that lint and particles contained in the lint-containing water are allowed to fall to the bottom of the tank. Multiple exits allow lint-filtered water to leave the lint filter.

Method for utilizing hydrocarbon waste materials as fuel and feedstock
ActiveUS20060070912A1Low costDewatering/demulsification with mechanical meansRefining by heating/coolingFiberCarbon fibers
The fuel properties of petroleum hydrocarbon waste having an API gravity varying from about 5 to 30 are improved by heating the hydrocarbon to a temperature of about 35° C. to 90° C. and mixing the heated hydrocarbon stream with a suitable solvent to reduce the viscosity of the hydrocarbon, which is then separated by a centrifuge to obtain an aqueous phase stream, an oil phase stream, and a separated solids stream. The oil phase stream has a viscosity range of about 250 centipoise (cP) to about 1000 cP. The oil phase stream is utilized in a refinery, while a slurry fuel is prepared with the separated solids stream and aqueous phase stream as a feedstock for road asphalt, a fuel for a combustor, or a fuel for a gasification process. The oil phase stream is used for fuels and feedstock for making carbon fiber.

Process and apparatus for treating exhausted abrasive slurries for the recovery of their reusable components
InactiveCN101218068AReduce in quantityOrganic anion exchangersVortex flow apparatusCrystalline materialsSlurry
Process for completely recovering the reusable components of an abrasive slurry used in slicing crystalline materials of silicon, quartz or ceramics when it becomes exhausted and enriched with undesired waste matter. The process consists of an initial centrifuge separation of the exhausted slurry as such and of a wet size-sorting treatment of the fraction containing the abrasive grains obtained from the centrifuge, carried out in a battery of hydrocyclones or centrifuges connected in series. The section for the recovery and purification of the abrasive grains comprises a multifunctional apparatus that performs all the required operations within a single pressure vessel. The process enables the complete recovery of the reusable abrasive grains contained in the exhausted slurry as well as of the suspending or cutting liquid of the abrasive slurry, in order to reuse both components in the manufacturing process. The invention also concerns an apparatus for carrying out the treatment of exhausted abrasive slurries according to the process described.

A filter device is made up of: a filter portion having a fluid outlet at its axis, and a fluid inlet in a position away from the axis, in which a fluid containing particles is supplied at a predetermined flow speed from the fluid inlet to cause a swirling, particles are moved outward in a centrifugal state and the fluid from which the particles are separated is discharged from the fluid outlet, and the particles separated by slowing down the swirling are allowed to sink; and a settlement portion in which the particles that settle in the filter portion are allowed to settle. Thus, a fluid containing particles is supplied at a predetermined flow speed to cause swirling, the particles are separated by a centrifugal force caused by the swirling and allowed to sink and settle, and the fluid from which the particles are separated is discharged. A large amount of particles can be allowed to settle and be reliably removed in a short time with this small-sized and simple device. The filter device does not clog, does not need washing and exchanging work and keeps the costs low.

This invention relates to a process for removing solid matter from process liquids that are miscible with water. A brine made from water and dissolved salt and which is more dense than the process liquid is placed underneath and in contact with the mixture of process liquid and solid matter. The particles and pieces of solid matter move from the process liquid and then through the brine. In so doing the process liquid that is carried with the solid matter is displaced by the more dense brine.
