Internally Fed Rotary Drum Screen is an internally fed screening device with the flow being fed and distributed inside a screening cylinder. It is widely used to separate settleable solids from liquid in the municipal and industrial wastewater treatment plants.
Internally Fed Rotary Drum Screen can be designed to open type or fully covered type according to the onsite working condition.
Two Types of Screens
Perforated Screens----provide a high capture rate of materials bigger than the perforation size.
Wedge Wire Screens----minimize the risk of clogging and maximizes permeability ratio with the V-shaped profile.
Application: to filter flume water from beet washing process

Features
Working Principle
The rotary drum filter is mechanical filtration equipment, including transmission device, overflow weir water distributor, rinse water device and other significant components. The filter drum is made of stainless steel wedge wire screen. The working principle is that the treated water enters the overflow weir distributor from the pipe mouth; after a short period of steady flow, it evenly overflows from the water outlet and distributes the filter drum that rotates in the opposite direction. The water flow will generate a relative shearing motion with the inner wall of the filter drum, with high water efficiency, in which the solid is retained and separated, and tumbles by following the spiral guide plate in the filter drum, and discharges from the other end of the filter drum, and the wastewater filtered out from the filter drum flows out from the side sink under the flow guiding of protection cover from the right direction. The outside of the filter drum is equipped with a flushing water pipe. It is sprayed with pressure water (3Kg/m²) in a fan-shaped manner to flush and dredge the filter mesh to ensure that it always keeps good filtering capability.
