Rotary Vacuum Drum Filter (RVDF) is one of the most prevalent practices in the industry to dewater all kinds of sludge at the least capital cost. Even though these units consume higher power due to deployment of Vacuum Pump, these units are still preferred in given situations in view of their low cost maintenance in case of any machine problems. These units can be supplied in various sizes upto 1000 sq.ft. filtration area each unit. Depending upon the type of sludge, the dewatered solid discharge mechanism can be in different configurations e.g. Belt Discharge, Knife Discharge, String Discharge etc. These units can also be provided in carbon steel and stainless steel construction to meet specific application requirement. The RVDF is supplied complete with filtrate receiver, moisture trap and other accessories like Pumps, Vacuum Pumps, Blowers etc.
