Model Development for Residual Chlorine

Journal of Engineering Research and Reports, 2023
The research is to develop a mathematical model for the decay of residual chlorine at the nodes and compare with results from Epanet 2.0. All the influencing parameters of initial chlorine Ccl(init(o)), bulk decay (Kb), wall decay (KW) and travel time (t), were well represented and the equation is developed applying the differential form of the first ...

Experimental appraisal and numerical modelling of chlorine demand and decay in a typical drinking water distribution network in South Africa

Ecotoxicology and Environmental Safety
Safe drinking water requires sound monitoring and maintenance of residual chlorine within drinking water distribution networks (DWDNs) to suppress possible microbial regrowth.

Étude expérimentale et modélisation de la désinfection par le chlore des eaux usées épurées [PDF]

, 1998
Pour étudier la désinfection d'une eau usée épurée au stade secondaire, traitée à l'hypochlorite de sodium, des essais en réacteur fermé ont été effectués en utilisant des doses variant entre 1 et 10 mg de chlore par litre. Les résultats obtenus montrent

Structural biology of ferritin nanocages

FEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

FEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Control of sulfides and coliphage MS2 using hydrogen peroxide and UV disinfection for non-potable reuse of pilot-scale anaerobic membrane bioreactor effluent

Water Research X, 2021
Anaerobic membrane bioreactors reduce the energy cost of wastewater treatment and meet filtration requirements for non-potable reuse. However, sulfides (H2S/HS−) formed during anaerobic treatment exert a high chlorine demand and inhibit UV disinfection ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

FEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
