Why is preliminary pretreatment necessary in pressure distribution systems?

Preliminary pretreatment is crucial in pressure distribution systems primarily to protect the distribution components from solids. In these systems, raw wastewater can contain solid particles that, if not treated beforehand, can lead to clogs and malfunctions in the distribution network. By implementing a pretreatment phase, such as a settling tank or a filtration system, these solid materials are reduced or removed before the wastewater is distributed. This approach not only ensures better efficiency and longevity of the system components but also minimizes the risk of system failures due to the accumulation of solids. Without adequate pretreatment, the operational effectiveness of the pressure distribution system can be severely compromised.
