Mathematical modelling of activated sludge systems is used widely for plant design, optimisation, training, controller design and research. The quality simulation studies varies depending on the project objectives, finances expertise available. Consideration has to be given model accuracy amount time required carrying out a study produce desired accuracy. Inconsistent approaches insufficient documentation make assessment comparison results difficult or almost impossible. A general framework...
Abstract To move today’s agricultural and urban systems towards tomorrow’s circular economy respond to climate change, it is imperative turn organic residues wastewater into resourceful assets. This article discusses the changes that are needed in research drive this paradigm shift go from a “losses waste” situation “resource opportunities” ambition. The current lines of aim maximise use value biomass or propose new organisational schemes driven by technical innovations. Exploring pathways...
The objective of this paper was to investigate the usefulness new multi-criteria measures evaluate a control strategy through Benchmark protocol. Using case study in which respirometry-based strategies are evaluated, proposed were calculated. An economic index including weighted investment and operating costs (termed Total Cost Index--TCI) appears more powerful than grey-scale presentation approach. latter approach, it is hard reflect relative importance criteria investigated, makes...
This paper serves as a problem statement of the issues surrounding uncertainty in wastewater treatment modelling. The proposes structure for identifying sources introduced during each step an engineering project concerned with model-based design or optimisation system. It briefly references methods currently used to evaluate prediction accuracy and discusses relevance evaluations model applications. aims raise awareness initiate comprehensive discussion among professionals on issues. also...
The Good Modelling Practice Task Group (GMP-TG) of the International Water Association (IWA) is developing guidelines for use Activated Sludge Models (ASM). As part this work group created and sent out a questionnaire to current potential activated sludge model users in 2007. objectives were (i) better define profile ASM users, (ii) identify tools procedures that are actually used (iii) highlight main limitations while building using ASM-type models. Ninety-six answers received from all over...
This study aims at synthesizing experiences in the practical application of ASM type models. The information is made easily accessible to model users by creating a database modelling projects. includes answers questionnaire that was sent out 2008 provide inputs for Scientific and Technical Report IWA Task Group on Good Modelling Practice – Guidelines use activated sludge models, literature review published analysed determine which biokinetic parameters are usually changed modellers, ranges,...
Abstract Gas–liquid mass transfer in wastewater treatment processes has received considerable attention over the last decades from both academia and industry. Indeed, improvements modelling gas–liquid can bring huge benefits terms of reaction rates, plant energy expenditure, acid–base equilibria greenhouse gas emissions. Despite these efforts, there is still no universally valid correlation between design operating parameters a coefficients. That why current practice for oxygen to apply...
The objective of this work was to analyse the impact different geometric and operating parameters on alpha factor value for fine bubble aeration systems equipped with EPDM membrane diffusers. Measurements have been performed nitrifying plants under extended treating mainly domestic wastewater. 14 showed that, wastewater treatment very low F/M ratios, is comprised between 0.44 0.98. A new composite variable (the Equivalent Contact Time, ECT) has defined makes it possible a given tank, knowing...
Aeration is an essential component of aerobic biological wastewater treatment and the largest energy consumer at most water resource recovery facilities. Most modelling studies neglect inherent complexity aeration systems used. Typically, blowers, air piping, diffusers are not modelled in detail, completely mixed reactors a series used to represent plug-flow reactors, empirical correlations describe impact operating conditions on bubble formation transport, oxygen transfer from bubbles bulk...
