Modeling Chlorine Decay in Drinking Water Distribution Systems using Aquasim
Chemical Engineering Transactions, 2017 The main purpose of drinking water distribution systems or networks is to supply water of impeccable quality to consumers according to their demand. Problems relating to declining water quality in natural water bodies have been on the increase around the

Self-adaptive amorphous CoOxCly electrocatalyst for sustainable chlorine evolution in acidic brine
Nature Communications, 2023 Electrochemical chlorine evolution reaction is of central importance in the chlor-alkali industry, but the chlorine evolution anode is largely limited by water oxidation side reaction and corrosion-induced performance decay in strong acids.

Impact of Booster Chlorination on Chlorine Decay and THM Production: Simulated Analysis
Journal of Environmental Engineering, 2009 The effect of conventional and booster chlorination on chlorine residuals and trihalomethane (THM) formation in drinking water distribution systems was modeled using the EPANET hydraulic modeling software. The model results suggest that booster chlorination may allow utilities to meet disinfection goals better by carrying chlorine residuals to remote ...

A Mathematical Model for Variable Chlorine Decay Rates in Water Distribution Systems
Modelling and Simulation in Engineering, 2019 A model for relating the time-dependent variable rate of reaction to the decay of chlorine residual in water is developed based on the initial chlorine dose, molar concentrations of reactants, and the rate constant itself.

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers
FEBS Letters, EarlyView.Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be
