उत्तर
Wastewater treatment generates a large quantity of sludge, which can be treated by anaerobic digesters.
Explanation:
During wastewater treatment, the solid part that settles at the bottom is called sludge. This sludge is treated in anaerobic digesters, where microorganisms break down organic matter in the absence of oxygen, producing biogas (mainly methane) and reducing the volume of waste.
