Digital Twins (DTs) are on the rise as innovative, powerful technologies to harness power of digitalisation in WRRF sector. The lack consensus and understanding when it comes definition, perceived benefits technological needs DTs is hampering their widespread development application. Transitioning from traditional modelling practice into DT applications raises a number important questions: When model's predictive acceptable for DT? Which frameworks most suited applications? data structures...

The poultry industry, a cornerstone of global food security, produces substantial volumes wastewater containing veterinary antibiotics. These contaminants exacerbate the issue antibiotic resistance, posing severe environmental and public health threats. Despite extensive research on human pharmaceuticals, removal antibiotics from slaughterhouse remains underexplored. Environmental nanoremediation technologies present promising solutions with their distinctive properties selective remediation...

This study presents an extensive plant-wide model-based assessment of four alternative activated sludge (AS) configurations for biological nitrogen (N) and phosphorus (P) removal under uncertain influent loads characteristics. Zeekoegat wastewater treatment plant (WWTP) in South Africa was chosen as case due to its flexible design that enables operation different AS configurations: 3-stage Bardenpho (A2O), University Cape Town (UCT), UCT modified (UCTM), Johannesburg (JHB). A metamodeling...

The feasibility of a biological (EcoflushTM) and/or electrocoagulation (EC) treatment system in removing chemical oxygen demand (COD) and fats, oils, grease (FOG) from poultry slaughterhouse wastewater (PSW) were studied. response surface methodology (RSM) was used to identify the optimum operating condition for EC its integration with EcoflushTM as pre-treatment removal lipids. conditions obtained at pH 3.05, current density 66.9 A/m2, 74-min time, without Ecoflush™. These produced...

Having certain bacteria called phosphorus-accumulating organisms (PAOs) is important for getting rid of phosphorus (P) in wastewater from homes. This happens a process enhanced biological removal (EBPR), where PAOs are active activated sludge. To design and make EBPR processes work better, we need to have an in-depth understanding how work. The best way learn about them by studying laboratory. study undertook culture these microorganisms the A University Cape Town membrane bioreactor...

Achievement of good effluent quality is always the main goal for wastewater treatment plant (WWTP) systems. However, these WWTPs have developed further objectives that include efficient design and strategic control options, with prospect their conversion into waste resource recovery facilities (WRRFs) operate on reduced energy costs. With all aspects becoming an intrinsic part treatment, mathematical models simulate WWTP unit processes are increasing relevance achievement WRRF goals...
