This article will introduce the main mechanical equipment used in water and wastewater treatment in detail and explore their specific functions and roles.

s an integral part of modern society. Its purpose is to purify drinking water, protect the environment, and ensure that industrial and domestic wastewater can be discharged in compliance with standards. In these treatment processes, various types of mechanical equipment play a vital role. Different mechanical equipment plays their respective roles in different stages of water treatment. From pretreatment to final water purification, each link relies on the support of efficient and reliable mechanical equipment.

Mechanical equipment in the pretreatment stage

In the pretreatment stage of water and wastewater treatment, the main purpose is to remove larger suspended matter and particulate matter in the water to provide stable water quality for subsequent treatment processes. This stage usually includes screening, sand settling, oil removal and other processes. The following are commonly used mechanical equipment.
