Wilsonville WWTP Biosolids - Case Study
About the Project The new facility includes two new structures: a dewatering and drying building, and a head works building. There are five additional major structures, including a new aeration basin, stabilization basin, clarifier, a bio-tower and ultraviolet light channel structure. All of these are used in the various stages of treating raw sewage before it is discharged as clean water into ...

Verification of an alternative sludge treatment process for pathogen reduction at two wastewater treatment plants in Victoria, Australia
At South East Water wastewater treatment plants (WwTPs) in Victoria, Australia, biosolids are stockpiled for three years in compliance with the State guidelines to achieve the highest pathogen reduction grade (T1), suitable for unrestricted use in agriculture and landscaping. However, extended stockpiling is costly, may increase odour nuisance and greenhouse gas emissions, and reduces the ...

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, ...

Predicting concentrations of trace organic compounds in municipal wastewater treatment plant sludge and biosolids using the PhATE™ model
This article presents the capability expansion of the PhATE™ (pharmaceutical assessment and transport evaluation) model to predict concentrations of trace organics in sludges and biosolids from municipal wastewater treatment plants (WWTPs). PhATE was originally developed as an empirical model to estimate potential concentrations of active pharmaceutical ingredients (APIs) in US surface and ...

A Canadian township uses dewatering units to achieve septage disposal compliance - Case Study
In 2002, Ontario, Canada's legislature and the Ministry of Environment (MOE) produced a policy paper announcing their intent to eliminate the land application ofuntreated septage. While 90% of residents in Ontario used local sanitary sewers to dispose of their waste and therefore were unaffected by the policy, there were still more than one million residents in rural areas using septic tanks. ...

Two-phase anaerobic digestion for class a biosolids at moccasin bend WWTP
The Moccasin Bend Wastewater Treatment Plant (WWTP) provides treatment for the City of Chattanooga, Tennessee and the surrounding region. The City has completed upgrades to the solids handling facilities to treat and dewater the primary solids and waste activated sludge (WAS) from the WWTP. This paper summarizes the process to handle the primary solids and the start-up process. Primary solids ...
