Belts/Drum

Vacuum belt filters are best suited for continuous solid/liquid separation of bulk material when additional or multiple steps are required before the final dewatering.  Belt filter presses use single or double moving belts to dewater sludges continuously through a combination of gravity drainage and compression.  Belt filter presses were introduced into the U.S. mainly because of its ability to dewater secondary sludges and because its energy requirements are significantly lower than centrifuges and vacuum filter dewatering equipment.
