A separation apparatus for separating an unwanted substance from an extraction target includes a forming unit configured to form a separation chamber through which the extraction target passes, and a suction unit communicating with the separation chamber in a direction crossing a passage direction of the extraction target and configured to suck air in the separation chamber. The forming unit includes an inlet for the extraction target, which communicates with the separation chamber, and an outlet for the extraction target, which communicates with the separation chamber, and the air is sucked from the outlet into the separation chamber by suction of the suction unit.

Disclosed is a system and method for treating municipal and sanitary wastewater that uses only mechanical devices and processes, which eliminates biological processes and settling tanks. The system includes a three-output Richter-type separator that separates wastewater into three fluid streams according to the specific gravity of the solids within the fluid streams. The lighter-than-water and heavier-than-water solids streams are combined and the resultant sludge is mechanically dewatered without intermediary biological-process systems or sedimentation. The partially-clarified water component can be directly filtered by a membrane filter and optionally optically or chemically disinfected for reuse or disposal. The system advantageously simplifies municipal and sanitary wastewater treatment eliminating traditional primary and secondary treatment stages, and significantly reducing the system's operational footprint. The system and method can be scaled to very large municipal systems.

An improved process and apparatus for separating organics and inorganics from waste material with a specific object of preparing the separated organic fraction for the production of biogas or other methods for diverting organics from landfills. Waste material, such as municipal solid waste or source-separated organic waste (SSO), is subjected to a first separation treatment that separates organic and inorganic waste components. The apparatus includes a hopper to receive contaminated organic waste from different sources, a vertical separator that separates the inorganics from the organics by creating a vortex effect in a stationary filtration drum by which the solid contaminants (paper, plastic, metals) are blown in a spiral pattern upwards and removed from the top, while the organic fraction is removed from the bottom.

Such apparatus is improved through novel methods to reduce or eliminate blockages and their associated downtime, and to increase the efficiency of the separation process.

A cleaner is provided. The cleaner includes a suction head, a dust collector connected to the suction head, and a fan motor provided to generate a suction force inside the dust collector, wherein the dust collector comprises a housing having an inlet and an outlet, a fixed body arranged inside the housing, and a rotating body rotatably provided between the housing and the fixed body.

A separator for removing dirt particles from an airflow, the separator comprising a first separation stage having an impeller, and a second separation stage having one or more cyclone bodies arranged in parallel, the first separation stage being upstream of the second separation stage. The impeller generates the airflow through the separator and concentrates the dirt particles within the airflow to produce a clean portion and a dirty portion of airflow, and wherein only the dirty portion of airflow is passed through the second separation stage.

A cyclonic separation and materials processing method and system is presented in which materials entry at one end and which is arranged so that the materials that enter will be given a tangential velocity component as they enter. Specific embodiments include a three-dimensional sorting system with the use of an outward centrifugal motion and up/down (or vertical) motion flow of water or other media, which can be thought of as a three-dimensional separation.

A cyclone separator wherein the tapered tip of the conical hollow body faces downwards. The air separator has at least one immersion tube which abuts the conical wall of the conical hollow body and which protrudes upwards within the conical hollow body, the conical hollow body tapered tip which faces downwards being connected to an outlet for fine material. The first cylindrical hollow body is equipped with a rotating rod basket which is enclosed by a static circular conveyor trough for coarse material, the conveyor trough resting against the lower outer circumference without contacting same. The conveyor trough for coarse material is connected to an outlet out of the cylindrical hollow body, and the volume enclosed by the rod basket is fluidically connected to the conical hollow body.

An apparatus for removing dirt from an airflow, the apparatus comprising an air inlet, an impeller for generating an airflow through the apparatus and for generating swirl within the airflow, the swirl throwing the dirt radially outwards and producing an outer dirty portion and an inner clean portion of airflow downstream of the impeller, and one or more splitters downstream of the impeller that bifurcate the airflow, separating the outer dirty portion from the inner clean portion.
