Garvey Resources recently completed a Biosolids Management plan For Bergen Point Plant in Suffolk County, NY- The plan evaluated alternatives for a Municipal wastewater treatment plant which produces 300 tons per day of wastewater residuals. The scope included evaluation of a wide array of alternatives for biosolids processing, end use and disposal. The study evaluated dewatering alternatives, odor control, heat drying, alkaline stabilization, composting, incineration and landfill disposal. A decision matrix was developed based on input from plant managers and staff to rate the processing and end use alternatives. The approach was to consider the personality of the facility by using the available skills and resources unique to the facility. Work included a survey of prices for wastewater solids processing and disposal in the mid Atlantic region as well as market pricing of biosolids products.

Abington Wastewater Treatment Plant- Biosolids Management Report. This study took a holistic approach to biosolids management decision making. This residential community in the Philadelphia suburbs had been plagued with odor complaints and escalating costs. The comprehensive study evaluated digester operation and recommended operating and mechanical changes, evaluated bench test results of various dewatering equipment, identified and evaluated end use and disposal alternatives, conducted an odor audit and conceptual design of odor control equipment, estimated costs for digestion, dewatering and end use of the biosolids.

Evaluation of Thickening Alternatives 1997 - Lead investigator for Upper Montgomery Joint Authority municipal wastewater treatment plant thickening evaluation. The benefits of thickening at this plant included increased detention time in digesters and reduced costs for hauling and land application or disposal of liquid biosolids. Alternatives evaluated included rotary drum thickening, gravity belt thickener, centrifuge thickening and a no action alternative. The costs evaluated included capital, O&M labor, monitoring, electricity, polymer, hauling costs, land application costs and tipping fees. The report also provided detailed information on operating experience at other facilities and demonstrated performance on similar types of wastewater solids.
