Journal ArticleDOI
Chemical Oxygen Demand and the Mechanism of Excess Sludge Reduction in an Oxic-Settling-Anaerobic Activated Sludge Process
Kyoung-Jin An,Guanghao Chen +1 more
TL;DR: A modified activated sludge process, called the oxic-settling-anaerobic (OSA) process, achieved effective reduction in excess sludge production through the insertion of a sludge holding tank in the sludge return circuit to provide an anaerobic sludge zone.
Book ChapterDOI
Modelling of the Simultaneous Removal of Organic Substances and Nitrogen in a Biofilm
TL;DR: In this paper, a mathematical model of the simultaneous removal of organic substances and nitrogen compounds in a biofilm reactor was developed, taking account of the relationships between oxidation, nitrification, denitrification, and mass transport.
Journal ArticleDOI
The feasibility study of autotrophic denitrification with iron sludge produced for sulfide control
TL;DR: It was shown that ferrous hydroxide and ferrous sulfide provided similar nitrate reduction rates of around 0.02 mmol N/m2/d in this study, indicating total surface area would be the key parameter for denitrification efficiency for the solid phase electron donor.
Journal ArticleDOI
Enhanced catalytic degradation of aqueous doxycycline (DOX) in Mg-Fe-LDH@biochar composite-activated peroxymonosulfate system: Performances, degradation pathways, mechanisms and environmental implications
TL;DR: In this paper, the Mg-Fe-LDH@biochar composite was firstly fabricated and applied for effectively activation peroxymonosulfate (PMS) for aqueous doxycycline (DOX) degradation.
Journal ArticleDOI
Systematic evaluation of a dynamic sewer process model for prediction of odor formation and mitigation in large-scale pressurized sewers in Hong Kong.
TL;DR: The model was employed to systematically assess the long-term effects of three commonly used control strategies, i.e. addition of nitrate salts, addition of biocides, and hydraulic flushing, on sulfide formation and to predict sewer biofilm compositions and reveals that the effect of odor mitigation measures on sulfides control varied with time.
