Bar screens are used in the primary treatment of effluent/sewage to segregate larger impurities from the wastewater. The main purpose is to remove larger debris from the effluent so that it doesn’t harm the electro-mechanical equipment in the plant. We can provide it in MOC such as MS, SS, FRP, MSEP depending upon the effluent and requirement. The porosity ranges from 2 mm to 20 mm.

Mechanical Bar Screen Automatic Coarse Screen Wastewater Treatment PlantA mechanical bar screen is a device used in wastewater treatment plants to remove large solid objects like rags, plastic bottles, and sticks from the water flow by passing it through a grid of vertical bars, with a mechanism that automatically cleans the bars by raking the debris collected between them, allowing the clean water to continue downstream while the captured solids are removed for disposal; essentially acting as the first stage of filtration in the treatment process.

Key points about mechanical bar screens:

Function:

To remove coarse solids from wastewater, preventing damage to downstream equipment.

Components:

. Bar grid: A series of vertical bars spaced apart with specific gaps to catch large debris.

. Rake mechanism: A rotating or reciprocating rake system that travels along the bars to collect and remove trapped debris.

. Hopper: A collection area where the removed solids are deposited.
