  • Modelling impacts of seasonal wastewater treatment plant effluent permits and biosolid substitution for phosphorus management in catchments and river systems

    The issues of diffuse and point source phosphorus (P) pollution in river systems are presented using a catchment model to assess nutrient behaviour, seasonal effluent standards and biosolid substitution. A process-based, dynamic water quality model (INCA-P) has been applied to four UK catchments, namely, the Rivers Tywi, Wensum, Lunan and Hampshire Avon, to simulate water fluxes, sediments, ...

  • Biosolids Minimization using Integrated Alkaline Sludge Hydrolysis and Biological Nutrient Removal Process

     ABSTRACT This paper presents a pilot-scale evaluation of an integrated approach to sludge management utilizing a combination of biological nutrient removal and biosolids alkaline hydrolysis, as well as attempts to explore the impact of recycled alkaline hydrolysates on sludge yield and anaerobic digestion. The novel concept of converting an existing conventional activated sludge (CAS) ...

  • Nitrogen and Phosphorus-Rich Sidestreams: Managing the Nutrient Merry-Go-Round

    ABSTRACTMany wastewater treatment plants (WWTPs) in the Midwest are facing nutrient removal for the first time, while plants in other parts of the US and the world are struggling with permits that become more stringent with each cycle. Depending on the permit, in-plant sidestreams generated during biosolids processing can greatly affect plant operations and performance, particularly when these ...

  • Standardized characterization procedures: a necessary support to regulations

    Sustainable procedures for sludge/biosolids management require the development of strategies to reduce the amount of sludge to be handled and to produce higher quality biosolids. Therefore, realistic and enforceable regulations adapted to local situations must be developed, defined outlet procedures established and good quality products guaranteed. To this end, the definition of standardized ...
