A septic tank filter system includes a tank. The tank includes an inlet and an outlet, wherein the outlet is disposed on the tank below the inlet to enable a flow of wastewater to be gravity fed from the inlet to the outlet. A filter is positioned in the tank. The filter includes a frame. A filter media is disposed on the frame. The filter media is operable to filter the wastewater of waste material as the wastewater passes therethrough. A top opening is disposed on a top portion of the frame. A bottom of the top opening is located above the tank outlet and below the tank inlet. When the filter media is not clogged, a level of the wastewater remains below the top opening. When the filter media is clogged, the level of the wastewater rises until the wastewater flows over the top opening.

Equipment for sucking and extracting anodic sludge from cells for electro-refining or electro-winning of metals that allows the continuous and selective extraction of anodic sludge without interrupting electro-refining or electro-winning, preventing the anodic sludge from causing contamination in the copper cathodes and in the time in later stages of metal recovery, where the equipment comprises: a vacuum tank (2) that receives the extracted anode sludge, comprising an outlet valve (21) located in its lower part; a filter (25) resistant to acid (25) inside the vacuum tank (2) for the separation of the anode sludge from the sucked electrolyte so that the anode sludge remains in the filter (25) by a decantation process while the electrolyte passes to the lower part of the tank body; a vacuum system (3), connected to the vacuum tank (2), which generates a vacuum inside the vacuum tank (2) to generate the suction or vacuum aspiration of the equipment; and an anode sludge collector (1) comprising a transparent tube (11) where a first end (12) has a suction nozzle (14) connected, through which the anode sludge enters, and a second end (13) is connected to the vacuum tank (2); a regulating valve (15) mounted at or near said outlet end (13) of the transparent tube (11), which is in communication with the interior of the transparent tube (11) at one of its ends and at atmospheric pressure at the another end, where said regulating valve (15) allows the regulation of the suction pressure inside the anode mud collector (1) and the extraction generated in the suction nozzle (14).

A filter, for insertion into an inlet duct of a water filtration system, has an annular upper end delimiting an opening around a longitudinal axis and defining a filter diameter. A side wall extends, around the longitudinal axis, between the annular upper end and a bottom wall that extends opposite the opening. The side and/or bottom walls have orifices to allow water to flow therethrough while retaining solid elements. The sidewall wall comprises a plurality of arms that each extend between a lower edge, connected to the bottom wall, and an upper edge forming part of the annular upper end. Each arm extends along an adjustable inclination so that the filter diameter is variable according to the inclination of each arm. When the filter is inserted into the inlet duct, the inclination of the arms is adjusted so that the filter diameter is adapted to the inlet diameter.

A filter assembly includes a manifold having a fluid inlet and a fluid outlet and a filter housing having a filter medium provided therein. The filter medium defines an inner filter chamber and defining an outer filter chamber between the filter medium and the filter housing. The filter housing is removably attached to the manifold so as to provide a fluid flow path from the inlet into the inner filter chamber, through the filter medium into the outer chamber and out of the outlet. The filter assembly also includes a valve assembly mounted inside the manifold, and a by-pass channel defined inside the manifold between the fluid inlet and the fluid outlet. The valve assembly comprises a valve spool and a valve spring arranged in engagement with the spool to bias the spool into a first position and to compress, in response to a pressure differential across the valve spool.
