One illustrative system disclosed herein includes a separator vessel that is adapted to separate solids particles from a flow of a multi-phase fluid, a differential pressure sensing system that is adapted to measure a differential pressure of a column of the multi-phase fluid in the separator vessel and a control system that is adapted to determine at least one of a level, volume or weight of the separated solids particles within the separator vessel based upon at least the measured differential pressure of the column of the multi-phase fluid in the separator vessel.

A wastewater purification system that uses mechanical and chemical processes to separate contaminants from municipal and other sanitary wastewater, concentrates the resulting sludge for disposal, and purifies the resulting product water for reuse as irrigation water, potable water or for disposal. The wastewater purification system can be scaled from a mobile system mounted on a skid or a tracker trailer to a large municipal wastewater treatment system. The wastewater purification system can include a hydrocyclone feeding a flotation tank. Flocculant is added upstream from the hydrocyclone after air injection by a Venturi air injector or similar device. Coagulant is added before the air injection. A dose of flocculant is added after the hydrocyclone within the vortex of the hydrocyclone and before the wastewater exits near the top of the flotation tank.

The invention relates to an enclosure (10) of a fluid catalytic cracking unit in which an inner space is defined by a side wall (12) having a longitudinal axis extending substantially in the direction of gravity, said enclosure being provided with a plurality of mechanical separation cyclones (14, 16) located inside the inner space. The enclosure (10) comprises a supporting device (20) attached only to the cyclones (14, 16) by: an annular peripheral support element (202) extending along the side wall (12) in a plane perpendicular to the longitudinal axis (X), separated from the side wall by a predetermined clearance; and a plurality of beams (206, 208) extending in the same plane as the peripheral support element (202), the beams being rigidly connected to the peripheral support element and to at least one mechanical separation cyclone by one end or by an attachment part distant from the ends thereof.

A surface cleaning apparatus comprises a cyclone bin assembly having a sidewall surrounding a contiguous interior volume and comprising multiple segments of different profile and width.

An effluent processing apparatus is provided for a vehicle air brake charging system. The effluent processing apparatus has an inlet port through which effluent from a purge valve of an air dryer can be received and an outlet port. The effluent processing apparatus further has a quadric surface defining an effluent flow chamber that is connected in fluid communication between the inlet port and the outlet port. The quadric surface is provided for extracting contaminants from an effluent stream as the effluent stream flows from the inlet port along the quadric surface to the outlet port.

In order to provide an airflow sorting device having high accuracy and easy adjustment properties with a simple configuration, there are provided a conduit which has a central shaft line and which lets an object to be sorted to fall due to gravity on the inside of the conduit along the central shaft line; an air supply port which is provided at a lower part of the conduit and configured to blow air upward along the central shaft line; a suction port which is provided above the air supply port of the conduit and is an opening oriented downward of a suction pipe provided parallel to the central shaft line; and an input port provided above the suction port of the conduit through which the object to be sorted is input into the periphery of the suction pipe which is in the conduit. Sorting is performed in the sorting device according to whether or not the object to be sorted is being suctioned by the suction port together with a part or the entirety of an airflow generated in the conduit by the air blown from the air supply port, and an airflow adjusting body which is provided below the suction port in the conduit and blocks a falling path of the object to be sorted which falls due to gravity, is provided, and the airflow adjusting body includes: a vertex on the central shaft line; and an inclined surface having a sectional shape, sectional areas of which are similar to each other and increase in size downward, and a drag force which acts on the object to be sorted which falls due to gravity increases downward from the suction port.
