Product Description

The bar screen is a device used for the preliminary filtration of large solid materials in wastewater treatment systems, such as branches, plastics, and other large floating objects that could potentially clog the treatment process. They are made up of a series of vertical steel bars with gaps between them measuring approximately 1 to 3 inches. The main function of the bar screen is to protect downstream structures from the impact of large objects that could cause blockages in connecting pipes, and to separate and facilitate the removal of large debris carried in the raw water, which could compromise the effectiveness of water and sludge treatment, or at least make treatment implementation and operation more complex.

Bar screens can be manually or mechanically operated. Manual bar screens require frequent raking to remove accumulated waste, making this method labor-intensive, so only older plants use manual bar screens as their primary screening system. Mechanical bar screens use automated cleaning processes to prevent blockages by debris, typically equipped with screening compactors to convey waste to the processing area.

Types of mechanical bar screens include chain-driven bar screens, reciprocating rake bar screens, bar screens with suspended chains, and continuous belt bar screens. Chain-driven bar screens use continuous vertical chains with toothed rakes to clear debris from the screen surface. Reciprocating rake systems (also known as climber screens) have a single rake that pulls waste from the bottom to the top for processing. Suspended chain bar screens have a rake placed parallel to the screen, moving upwards to deposit waste into a collection chamber. Continuous belt bar screens consist of a continuous belt with many rakes on the screen.

As the first line of defense in wastewater treatment facilities, modern Mechanical Bar Screen Channels are trending towards higher automation and intelligent features, ensuring superior processing efficiency and minimizing manual tasks. These critical components are indispensable for the smooth operation of wastewater treatment systems, reliably intercepting and removing large solid particles to facilitate subsequent treatment processes with excellence.
