Which of the following is used as a sludge dewatering device?

Explanation:
Sludge dewatering focuses on removing water from thickened sludge to reduce its volume and make handling easier. A belt press accomplishes this with moving belts and rollers that mechanically compress the sludge, squeezing out water and producing a relatively dry filter cake. This combination of pressure and filtration is specifically designed for dewatering, which is why the belt press is the appropriate device. Mixing tanks are meant for blending or homogenizing streams, chlorination columns are used for disinfection, and air strippers remove volatile compounds from liquids. These processes serve different purposes, so they don’t achieve the dewatering goal the belt press is built for.
