A recirculating aquaculture system using a biofloc fermenter and aquaponics may include a breeding water tank that breeds farmed fish, a drum filter that filters breeding water drained from the recirculating aquaculture system; an automatic filtration system in which the breeding water of the drum filter is moved and purified; a biofloc fermentation system that supplies and mixes oxygen to backwash water of the automatic filtration system; and a plant cultivation system that cultivates plant with the breeding water mixed with stable and high-concentration oxygen moved from the biofloc fermentation system.

A liquid dispenser may include a container having an upper opening, a pump provided in the container, a pipe through which liquid discharged from the pump is transferred, a top plate having an upper surface over which liquid flows, a filter assembly provided below the top plate, a base provided below the container, and a thermoelectric element provided in the base to cool the liquid in the container.

Techniques for separating cuttings from liquid include circulating a drilling fluid that comprises a liquid and formation cuttings to a scree of a screen assembly that includes screen sections; vibrating the screen assembly during circulation of the drilling fluid; while vibrating the screen assembly, separating the liquid from the plurality of formation cuttings; while vibrating the screen assembly, separating a first portion of the formation cuttings of a first size from the drilling fluid with a first screen section; rotating the screen assembly; subsequent to rotating the screen assembly and while vibrating the screen assembly, separating a second portion of the formation cuttings of a second size different than the first size from the drilling fluid with a second screen section; directing the separated liquid through the screen assembly to a liquid outlet; and directing at least one of the first or second portions of the formation cuttings to a cuttings outlet formed in the screen.

The invention relates to a filter with a gasket applied in line shape at an edge of the filter. The invention suggests to apply the gasket with a nozzle which facilitates a gasket that is thinner and/or whose protrusion beyond the filter is lower than this would be feasible for example through injection molding.

A device and method providing a textured substrate member and filtration device. The filtration device has a substrate member with a textured surface and a uniform surface on a side opposite the textured surface. The textured surface includes protrusions configured to interfere with a liquid flow traversing the textured surface to remove particulates entrained in the liquid flow. When the substrate member is disposed beneath a liquid source directed over the textured surface, the textured substrate forms a gravity-fed liquid filtration system. Also, a method for filtering particulates from a liquid includes providing a substrate member having a textured surface and a uniform surface opposite the textured surface; the textured surface having protrusions; configuring the plurality of protrusions to interfere with a liquid flow traversing the textured surface and remove particulates entrained in the liquid flow; and disposing the substrate member beneath the liquid flow.

A separating system and method, of which the separating system includes a lower vessel including an inlet configured to receive a mixed fluid comprising a solid and a liquid. The lower vessel is configured to separate at least some of the solid from the liquid so as to produce a partially-separated fluid. The system also includes a first screen vessel configured to receive at least a portion of the partially-separated fluid, the first screen vessel including a first shell, and a first screen that is positioned within the first shell and at least partially removable therefrom, and a second screen vessel spatially oriented parallel to the first screen vessel and configured to receive at least a portion of the partially-separated fluid. The second screen vessel includes a second shell and a second screen that is positioned within the second shell and is at least partially removable therefrom.
