A Comparison of Coarse vs. Standard Filter Media Configurations – Granular Media Filtration Pilot Study
Abstract:As part of the South Bayside System Authority Wastewater Treatment Plant (SBSA) Dual Media Filter (DMF) Performance Study, a pilot study was conducted to assess various granular media configurations for the following parameters:
Filter runtimes (length of time in between filter backwash procedures)
Filter effluent characteristics
A pilot plant was installed at SBSA in November 2003 and used to conduct the abovementioned evaluation. The findings of the study revealed that utilizing granular media configurations (3.4mm – 6.9mm Effective Size (ES)) that are approximately 3-5 times coarser than the existing SBSA granular media configuration (1.4mm ES Anthracite over 0.6mm ES Silica Sand) results in filter runtimes up to 360% longer than the existing media, while generating filter effluent characteristics that meet National Pollutant Discharge Elimination System (NPDES) plant discharge requirements.
This work, along with additional research, initiated a plant-scale study to evaluate the findings of the pilot study. The results of the plant-scale study will be available in the winter of 2005.
