Which device is responsible for ensuring that solids and semi-solids are reduced to small particles in sewage systems?

The comminutor is a device specifically designed to reduce the size of solids and semi-solids in sewage systems. It operates by cutting and grinding these materials into smaller particles, which helps prevent clogs and facilitates smooth transport through the sewage system. By breaking down solids into smaller components, the comminutor ensures that the sewage can flow more easily through pipes, minimizing the risk of blockages and maintaining the efficiency of the wastewater treatment process.

In contrast, pumps are used to move sewage through the system, but they do not alter the size of the solids. Filters are designed to remove particles from liquids but typically operate on already processed streams rather than reducing the size of solids. Separators are utilized to separate different components within a mixture, but they do not process solid materials into smaller particles. Thus, the comminutor is the most effective choice for reducing the size of solids and semi-solids in sewage systems.
