It is the first cleaning stage in municipal and industrial wastewater treatment plants and protects equipment downstream.
The cleaning elements are comb plates which are fixed to the carrier beams. The beams are connected to two strands of chains that can easily be adjusted to suit different requirements. CHAINGUARDTM consists of vertical screen bars spaced down to tapered 6mm bars.
Features and Benefits:
Screen can be used for channels from 1m up to 3m wide, and up to 5m deep.
Smallest available bar gaps 10mm.
Flow range up to 2500l/sec.
Most common installation angle 75° to horizontal.
Very high screenings discharge capacity.
Very low headloss - high separation efficiency.
Chains pass around a wear resistant guide track at the bottom of the screen which removes the need for sprockets and bearings in the flow.
No wash water required.
