The Envirex® Scum Pipe removes surface scum accumulated by the flights in a rectangular sludge collector system.  They are a versatile product offering three types of operation:

Lever Operated Pipes - which are used where close control of scum is not required. 

Rack and Pinion Operated Pipes - which offer a precise removal of scum with a minimum amount of water. 

Worm Gear Operated Pipes - which offer the most precise control of scum removal.

Both Rack and Pinion and Worm Gear Operated Pipes can be manually operated or furnished with a motorized operator for additional labor cost savings during operation.
