What are the sludge dewatering machines? What types are commonly seen among those who do centrifugation? How to control it?
The main machines used for sludge dewatering include horizontal spiral sedimentation centrifuges, belt vacuum filters, belt press filters, and plate and frame filter presses. Horizontal spiral sedimentation centrifuges offer good performance: they enable the reduction of sludge moisture content, require less chemicals, occupy less space, do not cause secondary pollution, have low energy consumption, and require minimal maintenance. However, their downside is the high initial cost of purchase. Moreover, many manufacturers in China lacking proper technical expertise produce such equipment, which can lead to various problems if purchased from them. Band filters are simple, but the working environment is poor and secondary pollution occurs. Plate and frame filter presses have low levels of automation and require high labor intensity
