DESIGN CHALLENGES TO THICKEN WAS
Amorphous Trash/ Grit
February, 2011 HWEA Presentation
1) Overcome the high polymer cost from gravity belt thickener and rotary drum thickener.
2) Reduce the polymer cost to improve the digester function as well as the dewatering after digesters
3) Overcome the historically high power and maintenance cost from centrifuges.
4) Reduce the capital cost for the DAF systems as well as the centrifuges
5) Centrifuge specifically: prevent amorphous trash, plastics and sand/ grid to great problems with the centrifuge operation
