A fish pond filtration device includes a filter tank, a conical filter cylinder, a garbage collection trough, and a sewage pipe; the conical filter cylinder, the garbage collection trough and the sewage pipe are located in the filter tank; water discharge ports are provided in a bottom or a side wall of the filter tank, and the conical filter cylinder is in rotary fit with the filter tank; the garbage collection trough is disposed below a large-diameter end of the conical filter cylinder, a filter port and a sewage discharge port are provided in a bottom of the garbage collection trough, and the sewage discharge port communicates into a sedimentation barrel; and a water pump is disposed at one end of the sewage pipe, the water pump is located in a fish pond, and the other end of the sewage pipe extends into the conical filter cylinder.

A processing device includes a pump system, a valve system, a centrifuge, and a controller. A fluid flow circuit is mounted to the device to execute a procedure in which whole blood is processed into a red blood cell product, a plasma product, and a platelet concentrate product. The blood is first separated into red blood cells, buffy coat, and plasma using the centrifuge, with the red blood cells and plasma being removed from the centrifuge, while the buffy coat remains in the centrifuge. The fluid remaining in the centrifuge is circulated through the centrifuge to form a homogenous mixture. Once the mixture is formed, it is separated in the centrifuge into platelet concentrate and red blood cells. A platelet product is then collected by using whole blood or previously collected red blood cells to push the platelet concentrate from the centrifuge to a collection container.

An apparatus for the treatment of wastewater having: a primary treatment module with at least one solids separation filter; a secondary treatment module with at least one microflotation unit and at least one oxidation treatment unit placed downstream of the at least one microflotation unit, the at least one oxidation treatment unit has an advanced oxidation process module for performing chemical processes, the advanced oxidation process module performing an ozone and hypochlorite treatment; a tertiary treatment module including at least one membrane filtration unit; the apparatus provided with sequentially flowing wastewater from the primary treatment module, through the secondary treatment module, and to the tertiary treatment module. A method for wastewater treatment in an apparatus having as sequentially treating wastewater through the primary treatment module, the secondary treatment module, and the tertiary treatment module.

A filtration system is provided that includes a gearbox positioned in a geared turbofan engine. The system further includes an auxiliary lubrication system positioned in the geared turbofan engine and in fluid communication with the gearbox. The auxiliary lubrication system includes an auxiliary reservoir, an auxiliary pump in fluid communication with the auxiliary reservoir, an auxiliary return line extending between the gearbox and the auxiliary reservoir, the auxiliary return line configured to transport a lubricant from the gearbox to the auxiliary reservoir, and an auxiliary supply line extending between the auxiliary pump and the gearbox, the auxiliary supply line configured to transport the lubricant from the auxiliary pump to the gearbox. The system further includes a non-removable filter positioned in the auxiliary lubrication system. The non-removable filter is configured to prevent or limit debris that is suspended in the lubricant from flowing into the gearbox and/or the auxiliary pump.

An apparatus (2) and a method for pretreatment of organic waste from the Organic Fraction of Municipal Solid Waste and/or from food industries, upstream of an anaerobic digester. The apparatus comprises:—a squeezing-diluting-unpacking module (4) configured to receive an input waste stream (3) of packaged waste and a dilution fluid (10), to lacerate the packaging, and to output a coarser non-digestible stream (23) and a comparatively dirty and comparatively liquid slurry (26),—at least one settling module (30, 30a) configured to allow inerts in the comparatively dirty and comparatively liquid slurry (26) to sediment and to output a finer inerts stream (40) and a comparatively refined slurry (42),—a thickening/dewatering module (60) configured to separate and output a liquid stream (69) and a comparatively dewatered slurry (72).

A method and apparatus for collecting agricultural manure in a confined animal feeding operation includes a separator which receives heavy manure removing particulate from suspension to produce light manure. Heavy manure is collected to a volume of heavy manure sufficient to substantially fill the first tank. Within the first tank, particulate migrates, due to the influence of gravity to form a layer containing manure comprising a lesser density of particulate than is present in the volume of heavy manure. Additional heavy manure buoys the layer such that the upper surface exceeds a height of a weir. The weir is situated in a channel communicating between the first tank and a second tank configured to receive light manure from the separator.
