The invention is directed towards methods and apparatus for improving the accuracy of monitors measuring the property of spray water used to cool a molten metal strand in a continuous casting operation. The method utilizes a highly effective slid-sieve to remove particles from sample water that would otherwise jam the monitor or would break the monitor. This particle removal results in the monitor providing more accurate measurements which in turn results in lower operating expenses, reduced maintenance costs, and production costs.

A padded grating system comprising sheets of multiple composite members secured together with multiple support bars or battens, wherein each composite member preferably consists of an elongated rigid bar with a foam layer adhered thereto which are encapsulated by a PVC or plastic water impervious tube or sleeve that has been heated and shrunk thereon. The sheets are specifically designed to be used in connection with water rides such as the FlowRider and can be modularly installed on site to cover certain drainage areas. The composite members are preferably made by gluing the rigid bars onto a sheet of foam and cutting the foam sheet to form the composite members, and after the tube or sleeve has been heat shrunk around each one, the ends of the composite members are then cut and sealed.

A strainer assembly for a pressurized fluid system having a pressure vessel with an oppositely directed inlet and outlet located thereon at a common elevation and a drain port in the bottom. A tubular diverter is disposed in the pressure vessel with an annular member sealed about the lower end of the diverter at an angle to the diverter axis and having its outer periphery sealed about the pressure vessel with one side of the member above the inlet and the opposite side below the outlet and isolating the inlet from the outlet. A cover is releasably disposed in fluid sealing engagement over the upper end of the diverter and includes a cylindrical strainer retained in the cover by a support ring having outwardly extending portions connected to the cover; and, the support ring is sealed over the upper end of the diverter. Fluid from the inlet flows upwardly through the diverter through the support ring and into the strainer. Flow emanating from the strainer flows downwardly around the diverter to the outlet. Large debris settles downwardly through the diverter to the bottom of the pressure vessel and is removed by selectively opening the drain port.

A method for producing a screening device, the method comprising the steps of providing a screening device that includes a plurality of profiled bars and a plurality of bar holder packages associated with the plurality of profiled bars. The plurality of bar holder packages include a plurality of first bar holders and at least one additional bar holder associated with the plurality of first bar holders. The method including the further steps of inserting the plurality of profiled bars parallel to one another into the plurality of bar holder packages, and bending the plurality of bar holder packages such that the plurality of first bar holders and the at least one additional bar holder are bent at the same time.

A wetland system has a wetland structure and a wastewater treatment device. The wetland structure has several planting areas surrounded by hoardings, several planting frames arranged in the hoardings, growing substrates provided in the planting frames, and wetland plants growing on the growing substrates. The wastewater treatment device has a bar screen, a regulating tank, a hydrolysis acidification tank, a contact oxidation tank, an MBR membrane tank, and a clean water tank that are in communication with each other in sequence of waterflow and arranged underground. The bar screen is provided with several bars therein, a lift pump is connected between the regulating tank and the hydrolysis acidification tank, a drainage pump is provided between the MBR membrane tank and the clean water tan. The planting area is connected to the bar screen via pipelines, and the clean water tank is connected to the planting area via pipelines.

The invention relates to a grid bar for a screen grid (2) of a screen (3) comprising a multiple number of grid bars (1) arranged next to each other and spaced apart from each other, which serves the purpose of separating screening material from a flowing liquid, such as wastewater (5) flowing in a sewer channel (4). In accordance with the invention, it is proposed that the grid bar (1) consists, at least partially, of a plastic reinforced with fibers (6), whereas at least a part of the fibers (6) extend in a longitudinal direction of the grid bar (1). In addition, a screen (3) with a corresponding screen grid (2) is proposed.

A device for an inlet guard is provided. The device includes an inlet having an opening; a screen attached to the opening of the inlet; and a basket attached to the inner side of the inlet, the basket including: a first wire-grid wall located on the rear side of the basket and extending between the left side and the right side of the basket, a second wire-grid wall located on the front side of the basket and extending between the left side and the right side of the basket, and a third wire-grid wall located on the bottom side of the basket and coupled to the first and second wire-grid walls.

There is disclosed a trash rake system for use in clearing debris from an intake screen of an intake trash rack of a water intake port of a water use facility. The intake screen is configured to collect debris transported by water, for example, a river, to prevent the debris from entering the intake port of the water use facility. The trash rake system includes a track system, a movable support structure, a rack and pinion drive mechanism, and a controller configured to receive signals from an encoder on a drive motor and a proximity sensor system.

A rake system and method may include a framework, a chain, an elongated rail, a support arm, and an engagement feature. The elongated rail may be pivotably connected to the framework. The support arm may be connected to the elongated rail at a first point and may be pivotably connected to the framework at a second point. The engagement feature may be connected to the support arm and may be configured to engage the chain. The rake system may be configured to discard debris.
