Incorporating Sustainability into Biosolids Master Planning
Abstract:Following a detailed investigation into wet stream processes used at the City of Columbus (City) wastewater treatment plants, the City wanted to investigate the biosolids handling, treatment, and disposal processes and develop a draft Solids Treatment and Utilization Master Plan. In order to accomplish this, the Division of Sewerage and Drainage worked with Malcolm Pirnie, several Project Partner Firms, numerous experts, and The Ohio State University Center for Resilience to develop, analyze and select scenarios for the City's two wastewater treatment plants and Compost Facility. Following this investigation the City chose to deemphasize the use of incineration and focus on beneficial reuse such as land application and composting as final disposal options. In addition, the City is considering several options to maximize the benefit from digester gas utilization. This solution will help the City reduce greenhouse gas (GHG) emissions, conserve energy, and save money.
