ROTARY DRUM SCREEN
for liquid / solids separation,
food grade stainless steel...

...an externally fed self-cleaning rotating drum screener, for separating liquids and solids, such as wastewater recovery, dewatering and/or solids separation. Similar in design to a Hycor Rotostrainer, but with a much simpler doctor-blade tensioning mechanism.

OPERATING PRINCIPLE:

• Unfiltered liquids are fed into a head tank which directs the liquid / solid slurry onto the outside of the 15 inch diameter by 22 inch long wedgewire strainer reel which has .029 inch sieve openings.
  
  
• The strainer drum cylinder rotates so that any solids which stick to the outside of the drum are scraped off by a simple weight-tensioned UMHW plastic doctor blade and drop off the edge.
  
  
• Meantime, the liquid is filtered through the sieve screen and discharges through a 3 inch diameter triclamp side bottom outlet.
