What issue may arise if the blades on the comminutor become dull?

When the blades on a comminutor become dull, their effectiveness in breaking down solids and debris in wastewater diminishes. The primary function of a comminutor is to reduce the size of solids, such as rags, sticks, and other debris, to prevent clogs downstream in the treatment process. Dull blades are less capable of efficiently shredding these materials, resulting in larger pieces passing through.

As larger solids enter the pump system, they can accumulate and cause clogs, leading to operational issues. This may result in increased maintenance costs and downtime as operators will need to frequently clear blockages. Therefore, maintaining sharp blades in a comminutor is critical to ensure that pumps operate smoothly without interruptions due to clogging by inadequately processed rags and debris.
