A separating system and method, of which the separating system includes a lower vessel including an inlet configured to receive a mixed fluid comprising a solid and a liquid. The lower vessel is configured to separate at least some of the solid from the liquid so as to produce a partially-separated fluid. The system also includes a first screen vessel configured to receive at least a portion of the partially-separated fluid, the first screen vessel including a first shell, and a first screen that is positioned within the first shell and at least partially removable therefrom, and a second screen vessel spatially oriented parallel to the first screen vessel and configured to receive at least a portion of the partially-separated fluid. The second screen vessel includes a second shell and a second screen that is positioned within the second shell and is at least partially removable therefrom.

An air purifier having a polygonal casing defining one or more inside corners, a cylindrical air filter extending along a center axis within the polygonal casing with a space formed between a radially outwards facing surface of the filter and at least one of the one or more the inside corners of the casing, and a filter cleaner at least partly located in the space. The filter cleaning has a cleaning member, a gear mechanism, at least one UV light source, a motor configured to drive the gear mechanism to thereby drive the radially outwards facing surface of a cylindrical air filter past the cleaning member and the at least one UV light source, and a filter cleaner housing encasing the motor, the cleaning member and the gear mechanism.

Some implementations can include method and system to collect and remove micro plastics from a water environment or ecosystem.

An air purifier and a filter cleaner are provided. The filter cleaner is configured to be mounted in an air purifier. The filter cleaner comprises a motor, a cleaning member and a gear mechanism. The motor is configured to drive the gear mechanism to drive a radially outwards facing surface of a cylindrical air filter or a filter holding case past the cleaning member. The air purifier can comprise a polygonal casing and the cylindrical air filter can be located inside the polygonal casing so that a space is formed between the radially outwards facing surface of the cylindrical air filter and the inside corners of the polygonal casing. The filter cleaner can be located in the space between the corner and the filter.

A brief description of the device

The machine works by frequency pressure, which is punctuated by a regular discharge of the pressure inside it and has a moving heart, a frequency movement which makes oil cleaning process not affect the basic oil properties and avoid the compression and adhesion of oil on the filters and clogged openings and oil enters the mechanism of the internal environment of the flattened and not the outer can save the deposits inside And disposal

Cleaning the surfaces of filters for the device it self because of its internal movement and there is space to collect the sediment, water disposal and cleaned manually or automatically

Some implementations can include method and system to collect and remove micro plastics from a water environment or ecosystem.

A washing machine including a tub disposed inside a main body, a drainage pump configured to cause the received water inside the tub to flow to an outside of the washing machine through a drainage passage, a first filter, arrangeable along the drainage passage, to filter out foreign matter equal to or greater than predetermined size from the water, and a second filter, arrangeable along the drainage passage, to filter out foreign matter smaller than the predetermined size from the water. The drainage passage includes a first connecting hose to guide the water to flow from the tub to the first filter, a second connecting hose to guide the water to flow from the first filter to the second filter, and a drainage hose to guide the water to be discharged from the second filter to the outside of the washing machine.
