Client: Suffolk County Department of Public Works
Location: Suffolk County, New York
Project Type: Alternative Sludge Processing Study
Project Period: 2000 - 2001

Major Components

  • Evaluation of Belt Filter Press & Centrifuge
  • Dewatering
  • Investigation of Anaerobic Sludge Digestion
  • Investigation of Chemical/Alkaline Sludge Stabilization
  • Investigation of Heat Drying (Pelletization)
  • Analysis of Multiple Hearth vs. Fluidized Bed Incineration
  • Investigation of Sludge Disposal (Hauling) Alternatives
  • Investigation into Emerging/Innovative Technologies
  • Provide Cost-effective and Feasible Recommendations to the County

Project Description

SCDPW-BPWWTP-AltSludgeProcessStudyThe County of Suffolk selected D&B to perform a study to evaluate sludge management alternatives for the Bergen Point Wastewater Treatment Plant (Sewer District No. 3). The 30 MGD facility generates primary sludge, waste activated sludge and scavenger waste sludge all of which are combined in the facilities blending tank system prior to dewatering and incineration and/or off-site disposal. The Facility currently processes 44 dry tons per day (DT/D) with an estimated future quantity of 75 (DT/D). An evaluation of existing systems at the plant was performed, as well as a review of available alternatives to increase overall capacity of the sludge processing systems, and to provide a reliable and cost-effective system. Recommendations were made for upgrading and replacement of the existing systems based on process evaluation and economic comparisons.

D&B Project Responsibilities

SCDPW-BPWWTP-AltSludgeProcessStudy-2D&B’s responsibilities included providing the County with a complete and thorough analysis/investigation to ensure the County continues to utilize the most cost-effective sludge
management approach for the Bergen Point WastewaterTreatment Facility.
