A magnetic separator for a central heating system comprises a housing, a separation chamber within the housing, and inlet and outlet ports extending from the housing. The inlet and outlet ports include push-fit connectors having collets surrounding the mouth of each of the inlet and outlet for releasing the connectors. The magnetic separator also has a release tool. The release tool has first and second bearing areas for bearing against the collets of the inlet and outlet connectors, and a handle region for enabling force to be applied, via the bearing areas, to both connectors simultaneously.

An apparatus and method for a grease trap for separating grease and solid waste from waste water. The grease trap includes a tank having a downwardly shaped bottom. An upwardly shaped baffle insert divides the tank into an upper chamber and a lower chamber. An outlet port near an upper part of the baffle allows waste into the upper chamber. An inlet invert in the tank receives incoming waste water, while an outlet invert removes water from the tank. A removable cover covers the tank and allows access for removal of accumulated grease and solid wastes.

The present patent document discloses filters and methods of filtering bucket wash water by stacking identical filters in a rotated position. In preferred embodiments, the method comprises: placing a first filter in a bucket; placing an identical second filter on top of the first filter wherein: the second filter is rotated by a radial angle with respect to the first filter and a first pair of tapered passages on the second filter that are longer than typical passages on the second filter are inserted into a second pair of tapered passages on the first filter such that a typical passage on the second filter is held above the first filter and a typical passage on the second filter does not axially align with a typical passage on the first filter.

A magnetic particle separator (10) suitable for separating magnetic and non-magnetic particles from a thermal fluid flowing in a heating system. The magnetic particle separator (10) comprises a hollow body (10A, 10B) configured with an upper particle separation chamber (11) and for circulation of the thermal fluid between an inlet and an outlet port (12, 13), and a quieting chamber (15) beneath the particle separation chamber (11) for accumulation of the particles separated from the fluid: an annular support element (21) for permanent magnets (18) being removably fastened outside the quieting chamber (15) of the separator (10).

An apparatus and method for removing particulates from a multiple-phase fluid stream is disclosed. The apparatus comprises a treatment chamber having a fluid inlet for receiving the multiple-phase fluid stream. The apparatus also comprises a recovery chamber having a gas channel and a liquid channel in fluid communication with the treatment chamber at a gas and a liquid port, respectively. The gas and liquid channels converge at an intake port of a fluid outlet for discharging particulate-removed gas and liquid.

The invention relates to a wastewater treatment plant, specifically a modular plant for the treatment of organic wastewater, in which the number of devices depends on the amount of water to be treated and on the quality of the starting water and that required for the water at the end of the process. The treatment plant includes multiple devices, each representing a treatment step, and the devices can be connected in series, in parallel or in series and parallel. In addition, the devices used in the process are designed to require a minimum amount of maintenance, owing to the inclusion of a self-cleaning system. Since the system requires minimal power and maintenance, it is considered optimal for use in rural communities, livestock farms or buildings.

The present invention relates to a removal device for removing gas bubbles and/or dirt particles from a liquid in a liquid conduit system or for removing a second liquid from a first liquid in the conduit system. The removal device includes a main channel for a main flow, the main channel having an entry and an exit which are configured to be connected to the conduit system, a housing which defines an inner space, at least one supply channel extending from the main channel to the inner space, at least one return channel extending from the inner space back to the main channel, directly or indirectly via a return chamber, at least one quiet zone in the inner space in which in use the liquid has a substantially smaller velocity than in the main channel. The quiet zone is configured to allow dirt particles or a relatively heavy liquid to settle at a lower end of the housing and/or gas bubbles or a relatively light liquid to rise to an upper end of the housing. The removal device further comprises means to remove dirt particles or relatively heavy liquid, and/or gas or relatively light liquid out of the housing.

This invention is a foreign substance removal apparatus that removes foreign substances in such a medium as a refrigerant that flows through a circulation path, the foreign substance removal apparatus including: a foreign substance sedimentation unit which is connected to the circulation path and is configured to settle the foreign substances; a foreign substance separation unit configured to separate, from the foreign substance sedimentation unit, the foreign substances settled in the foreign substance sedimentation unit; first pressure open/close means which is disposed on a bottom of the foreign substance sedimentation unit, and is configured to open or close in accordance with pressure inside the circulation path; and a foreign substance discharge pipe which connects the bottom of the foreign substance sedimentation unit and the foreign substance separation unit via the first pressure open/close means.
