The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading. More particularly, a filtering zone is located in an upper portion of a reactor vessel above a rough liquid distribution tray and a distribution tray.

Controlled-debris elements inhibit the formation of a fibrous/particulate debris bed that unduly increases the pressure head loss through the perforated plates of strainers in a nuclear power plant emergency core cooling system. In a loss of cooling accident, pumps draw cooling water through the plates, which retain on their surfaces fibrous material in the circulating water to prevent it from reaching the pumps while permitting entrained particulate matter to pass through the perforations. The controlled-debris elements have a specific gravity substantially the same as the circulating water so they are entrained in the cooling water that is drawn toward the strainers and intimately intermix with the fibrous and particulate matter in the cooling water. The elements are configured to provide open structures in the bed formed on the plate surfaces to distribute fibers in the flow away from the surface and maintain cavities between the elements for the particulates.

The invention involves a scale collection device that is located within downflow reactor head for removing solids from feed streams to increase reactor operating cycle time without impact on effective reactor space for catalyst loading and reactor pressure drop. More particularly, a scale collection device is located in an upper portion of a reactor vessel above a rough liquid distribution tray and a vapor-liquid distribution tray.

The present disclosure a mechanical filter element (2) for forming a static filter pack (11) to perform mechanical filtration of a liquid. The mechanical filter element (1) has one or more filter cell (19). The present disclosure also relates to a mechanical filter apparatus (1) having a filter chamber (10) containing a plurality of mechanical filter elements (2) for forming the static filter pack (11) to perform mechanical filtration of a liquid. The mechanical filter apparatus (1) is configured to generate a flow of the liquid through the mechanical filter elements (2) during filtration to form the static filter pack (11). Furthermore, the present disclosure relates to a method of mechanically filtering a liquid. A plurality of mechanical filter elements (2) each comprising one or more filter cell (19) are disposed in a filter chamber (10). During filtration, the liquid flows through the filter chamber (10) to establish a static filter pack (11) of said mechanical filter elements (2) to mechanically filter the liquid.

The present invention relates to a mixed-media kinetic filtration device which uses a family of various types of media substances to enable selectable filtration and filtrate process functions. More specifically, the filtration device and related process utilizes gradient-enabled nanomechanisms to separate one or more selectable molecules from a filtrate feed and, in some cases, further process those molecules. The family of media substances may be modified, adapted, or altered through treatment, stimulation, conditioning, or other methods to create desirable characteristics and/or create different filtration or process characteristics.

Systems and methods for generating and using a water filtration media containing date seed powder are provided. The method of generating the date seed powder for use in a water treatment system includes drying the date seeds, cleaning and removing the date seed envelopes, grinding the date seeds, and segregating the date seed powder according to a predetermined particle size. The method of using the date seed powder to treat water includes using a treatment tank with a date seed media bed layer, introducing water, and filtering suspended solids from the water stream using the date seed media bed layer. The system utilizing the date seed media bed layer includes a treatment tank, a date seed media bed layer, water inlets and outlets, backwashing equipment, and media support screens.

The present disclosure provides a water filter device generated using animal bone. In some embodiments, the water filter device comprises a tube containing a series of layers of animal bone granules.

A fluid strainer that is meant to remove debris from the flow of fluid through a strainer and that includes a housing having inlet and outlet ports. The housing defines an interior chamber through which the fluid flows. The fluid strainer including a single strainer basked disposed within the housing chamber. The strainer basket has open input end into which the fluid flows from the housing inlet and opposed side walls that extend in the direction of the fluid. The strainer basked further includes an open output end that is comprised of a pair of tapered output wall that direct the fluid flow to the housing outlet port. The strainer housing also includes a side inlet pipe for receiving filtration media.
