What is the primary function of a comminutor in sewage treatment?

The primary function of a comminutor in sewage treatment is to pulp or liquefy sewage solids before they enter the Collection, Holding, and Transfer (CHT) tank. This process is crucial because it reduces the size of larger solids and materials present in the sewage, making it more manageable for subsequent treatment processes. By effectively grinding or shredding these solids, the comminutor helps ensure that the sewage can flow freely through the system, minimizes the risk of clogging, and enhances the overall efficiency of the treatment process. This step is essential for preparing the sewage for further processing, such as separation or biological treatment, allowing for a smoother operation within the wastewater treatment facility.
