Vacuum drum filter is the simplest equipment of vacuum filtration. Cake is dewatered by the mean of pressure difference of inlet pipe and drum filter. Solid phase is remained on the filtration media. Drum filter is a rotary drum that filtration media is placed on it. Drum is placed in a tank with an agitator to prevent sedimentation. Vacuum drum filter is selected by filtration area that is ranged by 1 to 116 m2. Many parameters influence the time of cake formation, dewatering, washing and discharge.
Vacuum drum filters have a high efficiency. This filter’s design (piping, bearings, valves and worm gear system) make repair and maintenance much easier. More technical information is presented as followed:
