Project Summary:
The
City's existing solids dewatering system was in urgent need of a major
overhaul. Over the years, several dewatering systems were utilized, but the
City had the best results with belt filter press technology. Based on an
economical analysis, the City decided to proceed with a new solids dewatering
building.
At
the heart of the system are two BDP Industries Model 3DP® belt filter presses.
The 3DP utilizes three-belt technology. This provides advanced operational
flexibility while optimizing process performance as compared to traditional
two-belt machines – lower polymer usage, drier cake, clearer filtrate, higher
throughput, longer belt life.
Lou
Fallova is quite familiar with BDP equipment, as he operated BDP equipment at
the City plant through the 1980's. Lou's staff is now responsible for operating
and maintaining the sludge dewatering equipment.
Our special
thanks to Lou Fallova and Mike Madigan. Their support during this sensitive
project should be recognized. Both Lou and Mike leaped many personal and
professional hurdles in order to make this project a success for the City.
