Centrifuges vs Belt Presses: Weighing the Options

Many case studies show that switching out belt filter presses for centrifuges can reduce the hours worked per week without sacrificing production The main economic impact is the disposal of less solids With a centrifuge producing dryer solids, the weight by volume is less which in turn reduces the disposal cost 3 What are the advantages and disadvantages? Centrifuge
