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).

Systems and methods for disposing of blackwater are disclosed. A first vessel contains a screw running through the vessel from a first end to a second end. The screw is surrounded radially by a filter. The first vessel has a blackwater inlet adjacent the first end. An extrusion plate is adjacent the second end of the first vessel. A combustor vessel is configured to receive a solids component from the extrusion plate. A blackwater stream, consisting of a liquid component and the solids component, is passed through the blackwater inlet into the first vessel, is conveyed by the screw from the first end to the second end, and is pressurized against the extrusion plate. The liquid component is thereby forced from the blackwater stream through the filter and the solids component is forced through the extrusion plate into the combustor. The combustor is configured to combust the solids component.

A filter assembly a manifold having a fluid inlet and a fluid outlet and a filter housing having a filter medium provided therein. The filter medium defining an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing, the filter housing being removably attached to the manifold so as to provide a fluid flow path from the inlet into the inner filter chamber.

A washing pipe is mounted on a washing guide provided on an outer side of an outer cylinder screen of the screw press and includes a washing pipe body and washing nozzles provided in the washing pipe body and configured to discharge washing liquid flowing from an inside of the washing pipe body toward the outer cylinder screen. A washing pipe swing supporter is configured to support the washing guide to allow the washing pipe to swing between a discharge position and a separation position. The discharge position is a position where the washing pipe is mounted on the washing guide and the washing liquid is discharged from the washing nozzles toward the outer cylinder screen. The separation position is a position where the washing nozzles are farther away from the outer cylinder screen than in a state where the washing pipe is positioned at the discharge position.

A pool strainer basket insert system and method are contemplated in which a high porosity, coarse fibrous mass is inserted in a pool skimmer basket. Via optimization of the material properties of the fibrous mass and configuration such that approximately 50% of the fibrous mass is located above the waterline and 50% below the water line the problems of the prior art may be solved via the retaining properties of the fibrous mass, enabling insects and small organic matter to be retained and preventing their migration back to the main body of the pool.

A method for filtering particulate down to 0.5 micron from cooking oil at a filtration temperature of up to 425° Fahrenheit is provided. The method includes providing a filter having a non-woven panel of randomly oriented fibers of polyphenylene sulfide (PPS) material and exposing the filter to the oil for a period of time while applying a pressure or vacuum to move the oil through the filter for filtering particulate from the cooking oil.

A drain protector includes a basket and a wiper. The basket includes a basket body having first water openings. The basket body includes a seal at an upper first end and a retention member at a lower second end. The basket body is sized to be received in an associated drain, the seal for directly sealingly engaging an outer surface of the associated drain, and the retention member for directly engaging an inner surface of the associated drain. The wiper includes a wiper body having second water openings. The wiper body is removably mounted within the basket body for entrapping debris within water and removing the debris from within the basket body.
