What primary characteristic do coagulants and other chemicals influence in treatment processes?

Coagulants and other chemicals play a crucial role in the treatment process by directly influencing sludge characteristics. The addition of coagulants facilitates the aggregation of suspended particles, which leads to the formation of larger flocs that can be more effectively removed during the sedimentation phase. This process significantly impacts the quality and quantity of sludge generated, as well as the efficiency of the overall treatment system.

While substances like coagulants may also affect water clarity and other parameters, the primary focus of coagulants is to enhance the physical properties of the sludge, making it easier to separate from the treated water. Understanding the transformation of sludge during treatment is essential for optimizing the operation of water treatment facilities and achieving regulatory compliance.
