A method of controlling the water level in ground in which drainage pipes have been laid, said method comprising: a) providing the ground with water passing through the drainage pipes in a natural way and/or by active intervention using a control system, b) creating an underpressure or overpressure of water and/or air in the drainage pipes by means of the control system, thereby causing water or air to be extracted from or supplied to the soil via the drainage pipes, and c) programming the programmable control system in such a manner that the control system determines the points in time, durations, volumes and/or order of the water supply to the drainage pipes and of the generation of an underpressure or overpressure of water and/or air.

A filtration system includes a housing and a filter element positioned within the housing. The housing includes a first housing end and a second housing end. A drain opening is defined in the second housing end. The filter element includes a first endplate and a second endplate defining an endplate opening. Filter media is positioned between and extending axially between the first endplate and the second endplate. The filter media defines a central opening extending axially therein. A drain plug axially protrudes from the second endplate in a direction away from the filter media. The drain plug is configured to engage the drain opening and facilitate installation of the filter element into the housing. A lid is configured to engage the first housing end. The engagement between the lid and the first housing end occurs when the drain plug is disposed within the drain opening.

Apparatus and systems for laundry wastewater treatment are provided. Generally, systems include one or more grinder pumps for receiving raw wastewater from laundry operations, a lint remover in fluid communication with the grinder pumps, a sediment filter in fluid communication with the lint remover, an ozone treatment chamber in fluid communication with the sediment filter, and a carbon filter. Methods can provide for continuous treatment of laundry wastewater that can be reused in laundry operations, or passed to a wastewater stream (such as sewage).

A method for producing a screen body for a screen used in a screw press, which screen body comprises one or more openings on a screen surface. In order to achieve a particularly long service life, it is provided that the screen body is formed by a sintering process and/or an additive manufacturing process, in particular a 31) printing process. Further embodiments include a screen, in particular for a screw press, having a screen body Which has openings on a screen surface.

This insert-molded filter is obtained by insert-molding a cylindrically-shaped mesh into a resin body. This insert-molded filter is provided with: a body which is equipped with a first annular part, a second annular part, and multiple columnar parts connected to the first and second annular parts, and which has multiple openings formed so as to be separated by the multiple columnar parts between the first and second annular parts; and a mesh which is integrally molded with the body so as to cover the multiple openings separated by the multiple columnar parts. The body is provided with a resin introduction part that is disposed outside of the mesh in the radial direction of the first annular part.

A filtering system (10) includes a casing (12) internally defining a cavity (14) and has an inlet (16) configured to receive a fluid and leading into the cavity (14), and an outlet (18) configured to deliver the fluid coming from the cavity (14). A filtering assembly (100) is contained in the cavity (14) and is configured to be crossed by the fluid entering the casing (12) through the inlet (16), so as to trap any solid particles, in particular microplastic ones, contained in the fluid. A compacting assembly (200) situated in the cavity (14) is configured for collecting and compacting the solid particles trapped by the filtering assembly (100). A driving assembly (300) is configured to drive the compacting assembly (200).

Described is an extraction device for extracting compounds from plant material and a method for using such an extraction device. The extraction device comprises an extraction tank receiving plant material and dissolving soluble compounds inside the plant material into a solvent to form a micelle. A series of fluidly connected separation chambers separate purified compounds from the micelle, resulting in purified compounds in each of the separation chambers and solvent. A heat exchanger and a chilled reservoir are used for cooling and storing the solvent. A pump is used for pumping and circulating the solvent into the extraction device. Finally, a control system automatically controls temperature and flow in the extraction device.
