In the manual cleaning process for screens, how is debris removed?

The manual cleaning process for screens typically involves using a hand rake. This method allows operators to physically remove accumulated debris from the screen surface, ensuring that flow paths remain clear and that the screening system operates efficiently. A hand rake is a straightforward tool that provides operators with the control and precision needed to remove materials that may be caught in the screen openings, preventing blockages and optimizing the overall function of the wastewater treatment system.

In contrast, automated methods, such as mechanical arms or suction systems, typically fall under more advanced cleaning techniques and may not be applicable in a manual cleaning context. The use of chemical treatments is also not relevant to the straightforward task of physically removing debris from screens.
