A method includes performing a downhole operation in a borehole; capturing, during the downhole operation, downhole particles and drilling mud at the surface from the borehole into a screen of at least one shaker; shaking the screen to emit vibrations to separate the downhole particles from the drilling mud; defining a vibration limit for a normal operating condition of the at least one shaker; setting a vibration fault threshold based on the vibration limit for the normal operating condition; monitoring, using at least one sensor, the vibrations over time; and determining there is a fault condition for the shaker, in response to the vibrations exceeding the vibration fault threshold.

An assembly includes at least one container, an injection medium supply, at least one flow line extending from the injection medium supply to an interior portion of the at least one container; and a pressure transducer coupled to each of the at least one flow line.

A cover for a wastewater treatment unit is disclosed. The cover may include a retractable awning, a frame, and at least one rotating shaft. The retractable awning may be configured to cover the wastewater treatment unit when extended and allow access to the wastewater treatment unit when retracted. The retractable awning may be configured to protect the wastewater treatment unit from ultraviolet light. The frame may be provided to support the retractable awning above the wastewater treatment unit at an incline angle. The angle may allow visibility into the wastewater treatment unit when the retractable awning is extended. The frame may further include a handrail. A system including the wastewater treatment unit positioned within a basin and the cover is also disclosed. Methods of retrofitting a wastewater treatment system and methods of facilitating protection of a wastewater treatment unit are also disclosed.

A filter drum including: a drive shaft via which the filter drum is rotatably supportable and rotatably drivable; a filter drum body which is formed in a manner separated from the drive shaft, to which the drive shaft extends centrally and which filter drum body includes a first drum end wall, a second drum end wall, and a drum jacket wall which extends along the drive shaft between the first drum end wall and the second drum end wall and connects the first drum end wall and the second drum end wall to each other; and a first clamping ring set and a second clamping ring set, corresponding to the first drum end wall and the second drum end wall, respectively, by which, in a respective manner, the first drum end wall and the second drum end wall are, via radial clamping, fixedly connected to the drive shaft such that a driving torque applied to the drive shaft is correspondingly transmittable from the drive shaft to the first drum end wall and/or the second drum end wall and, thereby, to the filter drum body via the first clamping ring set and/or the second clamping ring set, respectively. The filter drum can be used in a vacuum and/or pressure filtration device for the filtration of a suspension having solid and liquid components.

Apparatus and methodologies are provided for pumping fluids from a body of fluids. Herein, an apparatus operably connected to at least one pump for pumping fluids from a body of fluids is provided, the apparatus having a pump hose with a first intake end for receiving the pumped fluids and a second outlet end operably connected to the pump, a pump intake assembly, fluidically connected to the intake end of the pump hose, the pump intake assembly having at least one fluid control valve, a rotatable filter cage, centrally disposed about the pump intake assembly, and at least one fluid injection pipe centrally disposed within the pump hose for supporting the at least one fluid control valve, and for injecting fluids to drive the rotation of the rotatable filter cage. Herein, methods of utilizing the fluid pumping apparatus are provided.

The invention relates to an arrangement for detecting a damage of a filter fabric (8) of a disc filter (1) at a disc filter unit comprising disc filters. The arrangement comprises a measurement bar (20) comprising two or more microphones (21), a store (45) including stored sound samples, at least one alarming means and a processing arrange-ment (43) for analyzing online sound or sound samples captured by the microphones (21). The processing arrangement (43) is connected to the microphones (21), the store (45) and the at least one alarming means. The invention also relates to a method for detecting a damage of a filter fabric (8) of a disc filter (1) at a disc filter unit.

The invention relates to a drum filter for water filtration and method therefor. The drum filter comprises: a housing; a filter drum arranged in the housing and comprising a filter surface, wherein the filter drum is rotatable around a shaft; an inlet for supplying water for filtering to an outward facing side of the filter surface for the purpose of collecting fouling on the filter surface; an outlet for discharging filtered water; and a sprayer for spraying clean the filter surface, wherein the sprayer is configured to spray substantially transversely over the outward facing side of the filter surface.

The present technology is directed generally to fluid treatment systems. In particular, several embodiments are directed toward filter supports configured to be positioned adjacent a filter belt within a filter belt filtration system. In one embodiment, the filter support can have a longitudinal axis generally parallel to the direction of movement of the filter belt. The filter support can include a plurality of struts spaced apart by a plurality of openings, and at least one of the plurality of struts extends across a portion of the filter support such that a longitudinal axis of the at least one strut is positioned at an angle with respect to the longitudinal axis of the filter support.

The present invention is directed to a drilling fluid reclaimer The reclaimer has at least one adjustable screen assembly for providing a leveling filter for reclaimed drill fluid. Used drill fluid is placed at the screen assembly at the front the of the screen assembly. The at least one screen is vibrated to separate large particulate matter from liquid drilling fluid. A second screen is provided for additional filtering. Large particulate matter is expelled by a chute at the back of the screen assembly. Drilling fluid passing through the screen is reclaimed for use with a drilling system.
