A modular, compact, mobile, dewatering and liquid-liquid separation and filtration system. The system processes incoming influents of slurries, solids and liquids at a high speed of operation and in large volumes. System is capable of being modularly scaled, allowing for a continuous steady state operation accommodating any slurry flow rate in a synchronous dynamic equilibrium process. Components and modules integrated into the system include a dynamic filtration clarifier 101 (DFC), a nested-filter dewatering cell 115 (NDC) and/or a compression filter press 125 (CFP). The DFC performs the primary dewatering phase of separating the primary water from the solids creating sludge. The NDC further breaks apart the solids of the sludge, removing interstitial water in a secondary dewatering phase, further lowering the moisture content of the sludge, while the CFP removes the tertiary water from the remaining solid particles by pressing the particles into a solid cake.

The present invention provides a new type of filtration system. Traditional designs required that personnel open the system to clean/change strainers while a process was in operation. This invention provides a straining system that allows process stream to be filtered in a manner completely internal to the process. The system includes dual strainers with a nitrogen purging system and solvent flush system. A creatively designed catch area is installed internal to the process to collect all solids that are flushed from the strainer system. The system remains completely closed for the duration of each production campaign, thus eliminating the safety hazard and labor requirement associated with opening a process system.

Liquid separator apparatus comprises a first screen assembly for screening fluids from slurry. The first screen assembly defines an enclosure. The apparatus also comprises a second screen assembly for screening fluids from the slurry and being disposed spaced-apart within the enclosure of the first screen assembly. A slurry pathway is defined between the first screen assembly and the second screen assembly. A first separated fluids stream pathway is defined outwardly of the first screen assembly, and a second separated fluids stream pathway is defined inwardly of the second screen assembly. An auger is positioned between the first screen assembly and the second screen assembly for advancing the slurry upwardly through the slurry pathway. A drive motor operates to turn the auger.

A method for unclogging the openwork sheath of screw extruders used for sludge densification. The sheath is formed by a stack of superposed elements that are spaced apart from one another by elastic spacers, the latter creating a gap between each of the elements. The liquid and gaseous fractions contained in the sludge are expelled through the gaps. The stack is compressed during an extrusion cycle, with the spacers thus being squashed, thereby reducing the thickness of the gaps. During an unclogging cycle, the pressure is released, the spacers then returning to their original thicknesses and in this way increasing the size of the gaps, thus making it easier to unclog the latter.

A system to treat effluent in a septic tank includes filter sections having kerfs. A strainer removes solid debris from the filter for removal without allowing the solid debris to pass. An aerator includes an eight to twelve inch diameter pipe 4 to 6 feet tall matching tank invert height. The aerator has bottom inlet holes, each with an elbow on the outside with a vertical standpipe taking effluent from the clear zone, sending it through the aerator. Air inlet piping is attached to a T shaped air diffuser producing bubbles traveling upward through plastic media. Aerator height is field adjusted to approximately 2 inches below static water level. Holes in the upper sidewalls just below the top let air bubbles out sideways. At its top, the aerator has a slotted, sliding, anti-turbulation collar adjusted to be one to two inches above the static water level.

The present invention provides a liquid treatment device capable of suppressing a decrease in cleaning performance. Provided is a liquid treatment device provided with a filter 2 inside a casing 1, comprising a discharge means 4, wherein the discharge means 4 comprises nozzles 41, 42 and a discharge pipe 44, the nozzles 41, 42 are arranged to open toward the filter 2, the discharge pipe 44 is arranged to discharge water introduced from the nozzles 41, 42 to an outside of the casing 1, and a first through hole 41h (42h) is formed on at least one of a side surface of the nozzles 41, 42 and the discharge pipe 44.

Trichomes, lupulins and other plant parts can be efficiently separated from plant biomass by continuous filtration. In some embodiments plant biomass is collected and combined with water to form a plant biomass mixture. The plant biomass mixture is passed through a filtration device in which the plant biomass mixture is continuously flowed through a filter material. The device includes a cleaning apparatus that cleans the filter material during the process. In some embodiments greater than 90% of the plant parts are collected from the starting plant biomass. The plant parts can be subsequently processed to obtain desired compounds. For example, trichomes can be separated from other plant biomass and subsequently processed to extract one or more cannabinoids or terpenes, such as THC and/or CBD.

A water-using household appliance includes a pump sump, a filter element arranged at least partially in the pump sump, and a nozzle unit arranged on the pump sump. The nozzle unit produces an annular flow between the pump sump and the filter element in order to remove dirt from the filter element, with the annular flow flowing around the filter element only in one direction of flow.

A device includes a compartment for separating the solids and liquids. The compartment includes a base that is concavely curved according to a cylindrical portion having a transverse axis and is formed of a sieve, an idler roller mounted transversely on an arm, a drive which actuates the arm, and resilient means for adjusting the pressure exerted by the rollers. Both the contact interface between the sieve and the roller and the rotational interface between the roller and the arm are made of a non-metal material on at least one of the two contacting surfaces that form each of the interfaces, such that, there is no metal-on-metal contact between surfaces moving relative to one another at the interfaces.

There is disclosed an apparatus for cleaning circular filter screens comprising at least one suction chamber fitted to a conduit of the dirt collection conduit system extending along a central axis of the housing of the filter screen. The suction chamber comprises a central nozzle through which fluid is forced to flow by virtue of a pressure differential between the outer surface of the filter screen and an extremity of the dirt collection conduit system. The fluid flow through the central nozzle creates a low pressure regime near the mouth of the central nozzle such that fluid is forced through a plurality of peripheral suction nozzles arranged around the central nozzle from the outer surface of the filter screen to the inside of the suction chamber, thereby forcing the dirt and retentate accumulated along the inner surface of the filter screen to be washed away.
