This book describes theory and approach for a comprehensive and applied physicochemical model for wastewater treatment. These are reactions which occur without a biological mediator, and are critical to both the biology of wastewater treatment, and stand-alone chemical treatment units. The book includes description of acid-base theory, solution ion pairing and non-ideality, participation with other phases, and chemical oxidation/reduction. Full implementation details are provided, including in a plant wide modelling context, and with respect to required extensions to biological models to describe more complex aspects of the iron-sulfur-phosphorous system, which requires all components of the model to be properly described.

Benchmarking of Control Strategies for Wastewater Treatment Plants
Wastewater treatment plants are large non-linear systems subject to large perturbations in wastewater flow rate, load and composition. Nevertheless these plants have to be operated continuously,...
Instrumentation, Control and Automation in Wastewater Systems
Instrumentation, control and automation (ICA) in wastewater treatment systems is now an established and recognised area of technology in the profession.
There are obvious incentives for ICA...
Sequencing Batch Reactor Technology
The report highlights various types of SBRs, design considerations and procedures, equipment required, and experiences gained from practical applications. This report will help both designers and...
Mathematical Modeling of Biofilms
Over 90% of bacterial biomass exists in the form of biofilms. The ability of bacteria to attach to surfaces and to form biofilms often is an important competitive advantage for them over bacteria...
Can TMDL Models Reproduce the Nutrient Loading-Hypoxia Relationship?
Anthropogenic nutrient enrichment of estuaries is a problem dramatically transforming coastal ecosystems worldwide (Diaz and Rosenberg 2008). Despite significant public and private sector...
Evaluation of Feasibility of Methods to Minimize Biomass Production from Biotreatment
This report presents the results of an evaluation of technologies that may result in less biomass production in activated sludge processes. The report summarizes the results of a comprehensive...
Influent Constituent Characteristics of the Modern Waste Stream from Single Sources
Available as eBook only
This research project characterized the composition of modern single residential source onsite raw wastewater and primary treated effluent (i.e.,...
Bioavailability and Characteristics of Dissolved Organic Nutrients in Wastewater Effluents
This study aims to investigate and assess:
1) the bioavailability of various P fractions, particularly dissolved P fractions (DOP), in advanced wastewater effluents
2) the nature and...
