Apparatuses, systems, and methods related to water treatment are generally described. In particular, clarifiers that may improve solids thickening and related systems and methods are disclosed.

The system (1) for accelerating settling in a settling tank (2) by recirculation of slowly sedimenting fine particles uses the Venturi effect caused by coaxial deflectors (14, 14′, 15, 24) promoting the agglomeration of particles in laminar currents (F1-F4) bringing them into contact with the sludge (3) of the main current (C1) entering into the system (1), which is entrained by the centripetal counter currents (C3) generated within the settling tank (2) towards the bottom (7) of the settling tank.

A stormwater treatment device includes a tank defining an internal volume and having an inlet and an outlet, a rotatable screen unit mounted within the tank, the rotatable screen unit being barrel-shaped to define a through path with an inlet end and an outlet end. The rotatable screen unit includes a screen structure with a plurality of screening openings for allowing passage of at least some water from the through path outwardly through the screen structure while inhibiting passage of trash items through the screen structure such that trash items move along the through path from the inlet end to the outlet end. The rotatable screen unit includes a plurality of external drive paddles that rotate with the screen structure and that interact with water that has been screened by passing outwardly through the screen structure interacts with the external drive paddles to cause rotation of the rotatable screen unit.

The present invention discloses a centrifugal fuel purifying apparatus, including, a center shaft, a centrifugal cylinder, a shaft seat, a rotating skeleton, a disc type guide plate, a fuel gathering impeller, a rotating wheel, a vacuum pump, a fuel outlet pipe, a fuel inlet, pipe, a fuel unloading box, a pollutant receiving box, a tank body and a PLC controller, wherein the alarm fuel tank is arranged at the top in a tank body of the fuel tank, a fuel level meter is disposed within the alarm fuel tank, a fuel inlet is provided on the upper part of one side of the alarm fuel tank above the fuel level meter, a fuel outlet is provided on the lower part of one side of the alarm fuel tank below the fuel level meter, and the fuel inlet is communicated with the centrifugal cylinder through the fuel inlet pipe.

Separating apparatus, comprising a sedimentation settler and a collection vessel disposed underneath and being in fluid communication with the sedimentation settler, the collection vessel forming a receiving chamber having an outlet at or adjacent to the chamber bottom and having an inlet opening, wherein the collection vessel is arranged such the flow direction of the fluid in the area underneath the sedimentation settler is substantially in line with the direction of the channels of the sedimentation settler.

An apparatus for purifying water to be purified is provided with a tank with a bottom to receive sediment, an inlet connected to the bottom itself, at least one pump, outside the tank and connected to the inlet, at least one conduit disposed axially inside the tank, diverging upward and fluidically connected to the inlet to receive pressurized water fed by the pump, and a hydraulic accelerator/mixer assembly disposed in the tank and which connects the inlet to the conduit. The hydraulic accelerator/mixer assembly is configured to increase the speed of the flow of water to be purified, introduced into the tank.

A method, system, and apparatus directed to an innovative approach for the treatment of stormwater utilizing hydrodynamic separator assembly designed to maximize flow movement for more efficient sediment removal and maximize water flow control.

The disclosure relates to a dental debris separator having a housing in the upper region of which a drainage zone for removing particle-containing liquid from an air flow which is loaded with the liquid. The housing has an inlet for the loaded air flow, leading tangentially into the drainage zone. Downstream of the drainage zone a separation zone for removing the particles from the particle-containing liquid is provided in the housing, said separation zone descending from the drainage zone to the separation zone, the drainage zone having a curved flow path that is delimited on its lower side by a crown of baffle elements.

A launder cover system for reducing or eliminating sunlight exposure so as to prevent algae growth in a tank such as a clarifier tank. The launder cover system generally includes a plurality of support members and a plurality of launder covers which are each independently pivotably connected to a tank wall of a tank, such as by using a mount. The support members are each pivotably connected to the tank wall by a pivot connector and the launder covers are each pivotably connected to the tank wall by a hinge connector. Each support member is positioned between a pair of launder covers, and each launder cover is positioned between a pair of support members. The support members function to support the launder covers in a raised or lowered position. A launder support may be connected to the channel wall to support the launder covers in their lowered positions.

A drain system for water quality. The drain system may include one or more baffles. The one or more baffles may be arcuate in shape. The one or more baffles may include one or more openings therethrough. The one or more baffles may be offset in elevation. The one or more baffles may include one or more flanges projecting therefrom. The one or more baffles may be implemented in a flow-through manhole application.
