Product Description:

Mechanical bar screens are widely used in sewage treatment plants to intercept large debris such as plastic and branches that may damage downstream equipment and clog pipes. As the core component of sewage treatment facilities, the normal operation of bar screens is the key to ensure the efficient operation of the treatment process.

The primary function is to intercept solid waste before wastewater enters the treatment system. When sewage (the influent) flows into the bar screen chamber, it first slows down through the bar screen before entering a filtration layer composed of parallel vertical bar screens. These bars are arranged at fixed intervals to specifically capture solid particles larger than their spacing dimensions. The treated wastewater then continues through the bar screen, where intercepted debris is collected and properly disposed of.

How the grilles work:

Mechanical grates employ multiple technologies to remove impurities: Some models feature automatic rake systems that directly clear solid debris from the grid, while others use conveyor mechanisms to transport waste to bins or hoppers. Certain facilities even install staggered grids in multiple rows to ensure all solid materials are intercepted and prevented from entering the processing system.

As the core equipment in wastewater treatment plants, the maintenance and operational status of bar screens directly impact the system’s efficiency. Proper maintenance involves regular cleaning of the screens and replacing worn or damaged components. Bar screens require periodic inspections to ensure proper functioning, with any issues identified and addressed promptly.

Beyond their primary debris removal function, bar screens provide wastewater treatment plants with additional benefits. By eliminating large debris, they protect downstream equipment like pumps and valves from damage. These screens also help reduce odor issues and clogging risks———problems that often plague wastewater treatment facilities.

In summary, mechanical bar screens play a vital role in ensuring efficient operation of wastewater treatment plants. Their primary function is to remove large debris from incoming wastewater before treatment processes begin, while also providing additional benefits such as protecting downstream facilities and eliminating odors. Proper maintenance and operation of bar screens are crucial for maintaining optimal plant performance and continuously improving wastewater treatment efficiency.

Features and advantages (compared with traditional manual grating)

• High degree of automation: can be operated 24 hours unattended, greatly reducing labor intensity.

• High cleaning efficiency: continuous or intermittent automatic cleaning to ensure smooth water flow and reduce head loss.

• Good sanitation: garbage should be removed in time to avoid the accumulation of organic matter and fermentation to produce foul smell and mosquitoes.

• High safety: no need to manually go down the well to clean and salvage, avoiding safety risks.
