CopaTrawl™ Screen

The CopaTrawl™ system is installed directly into the flow path of the fluid being screened. Solids are retained in the sack, thereby preventing downstream problems such as clogging of trickling filters or the pollution of surface waters following a storm event.
The CopaTrawl™ screen can handle larger flows than its sister product, the CopaSac® screen.

It is recommended that a lifting davit is used as a minimum requirement to facilitate removal of the trawl sack from the flow chamber.
The CopaTrawl™ screening system is capable of screening down to 6mm of settled sewage and can be made to fit into most sewage treatment applications as part of a new scheme or as a retrofit into existing works.
