What is the function of a cumminuter in wastewater treatment?

To measure total solids
To screen and cut large solids into small particles
To aerate the wastewater
To lubricate machinery

The correct answer is: To screen and cut large solids into small particles

The function of a cumminuter in wastewater treatment is to screen and cut large solids into smaller particles. This is essential in the treatment process because large solids can cause blockages and operational issues in downstream equipment, such as pumps and pipes. By reducing the size of these solids, a cumminuter ensures smoother processing and enhances the effectiveness of subsequent treatment stages. In the context of wastewater treatment, the cumminuter acts as a barrier to prevent problematic materials from disrupting the system. This function is crucial for maintaining the efficiency and longevity of the treatment facilities. The other options involve different processes that do not relate to the primary role of a cumminuter; measuring total solids, aerating the wastewater, and lubricating machinery are functions carried out by other equipment or processes within the wastewater treatment facility.
