What are comminutors used for?

Explanation:
Comminutors are mechanical grinders placed in the sewer system to break down large solids into smaller pieces. By reducing the size of tough or bulky waste, they prevent jams and make pumping and transport through pipes more reliable. This protection of downstream equipment is especially important near pump stations and in main sewer lines. They aren’t designed to remove oils or grease, which is a different treatment step, nor to screen out fine debris (that work is done by screens), and they don’t directly control odors.
