Drum filter/wedge wire drum screen

Rotary Drum Screens for industrial wastewater applications are designed to provide superior solids recovery from waste streams.

Drum screen for paper and pulp industries

Rotary drum screen,also called wedge wire drum screen. It is a type of rotary screen/drum screens that commonly made of stainless steel wedge wires or perforated plates and it is made of stainless steel V shaped wires and support rods. It has very efficient and reliable filtration effect. 
The screening elements can be either wedge wire spaced at 0.5-6mm, or 1-6mm perforated drums. Depending on the aperture size selected and the screen diameter.high quality sewage treatment Rotary Drum Screen is a reliable and well proven inlet screen for municipal sewage treatment plants, industrial wastewater and process water screening. Its operation is based upon a unque system that also allows a combination of screening, washing, transport,compaction and dewatering in a single unit.

Features:

  • Continuous slot openings significantly increase the open area and filtration efficiency.
  • V-shaped wire structures reduces clogging and ensures an uninterrupted flowing and working.
  • Supply back washing performance for high working efficiency.
  • Reinforced rods can bear high pressure during high speed rotary working condition.
  • Stainless steel material reduces corrosion and rust and make it durable and reliable.
  • Flange or metal ring ends make them easy to install onto the
  • It is features smooth surface and high filtering efficiency as well as self-cleaning and clogging resistance.

Working principle:

Within the inlet chamber the incoming medium is homogenized and the flow velocity reduced. The dammed up water passes a weir and runs through the wedge wire sieve drum while the solids are picked-up by the rotating drum and transported to a scraper. Being statically dewatered they are removed from the drum.

Applications:

They have been used in a variety of food & beverage and industrial wastewater applications including beef, hog, poultry, and seafood offal, protein rendering, fruit and vegetable processing, pulp & paper production.
