What does a comminutor do?

A comminutor is a device used in wastewater treatment that plays a crucial role in the preprocessing of sewage. Its primary function is to reduce the size of solids in the sewage. By breaking down larger particles into smaller pieces, the comminutor helps prevent clogs and blockages in the treatment system. This size reduction facilitates more efficient handling and processing of the sewage, as smaller particles can more easily move through the treatment plant without causing obstructions.

The options regarding heating sewage, monitoring tank levels, or transferring sewage focus on different processes involved in wastewater treatment, but they do not relate to the specific mechanical function that a comminutor provides in terms of solid size reduction. By understanding the role of a comminutor, one can appreciate how essential it is in ensuring the smooth operation of a sewage treatment facility.
