Sludge Dewatering Improvements

 

Chief Operator:          Keneck Skibinski

Engineer:                    Stearns & Wheler, LLC

 

Project Summary:

 

For many years, the Herkimer County facility was challenged with the high maintenance costs related to the use of their outdated dewatering equipment. The old plate and frame presses
required the use of a lime slurry and ferric chloride system. These chemical feed systems were expensive to operate and maintain. The 1990 treatment facility upgrade included a new belt dewatering press. A dry lime system is now used for sludge stabilization. This has
substantially reduced the maintenance for the chemical handling equipment. Average cake dryness is 26 percent by weight.

 

Ken Skibinski is responsible for the management of the dewatering system. For those who
know Ken, he has an unparalleled enthusiasm for his work. Ken’s pride is evident in the dewatering system, as he and his staff manage to keep the facility clean and safe at all times.
