AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
Lack of improved drinking water sources contributes a lot to many waterborne diseases caused by pathogens which include viruses, protozoa, bacteria or worms. It is essential to develop and promote treatment methods in order to provide pathogen-free safe dr ...
There is a need to reduce the economic cost of the energy geostructures and increase the efficiency of such systems, which will also rationalise the environmental impact. ...
In the diffusion model of chemical reactions, the encounter (reaction) rate between reactant particles is governed by the Smoluchowski equation, which is a diffusion equation in a field of forces. We consider crowded environments where the particles diffus ...
Kinetics and mechanisms of As(III) oxidation by free available chlorine (FAC-the sum of HOCl and OCl-), ozone (O-3), and monochloramine (NH2Cl) were investigated in buffered reagent solutions. Each reaction was found to be first order in oxidant and in As( ...
A new procedure for benchmarking analysis has been developed to evaluate the energy efficiency of a chemical process. Benchmarking is performed to identify process inefficiencies before developing energy enhancement measures. The new procedure combines typ ...
A comprehensive review. The kinetics of various types of chem. reactions and the influence of transport processes on the effective reaction velocity (macrokinetics) are described. A survey is given on methods to det. the kinetics of reactions. Criteria for ...
This article presents the analysis of the power efficiency of the inductive links used for remote powering of the biomedical implants by considering the effect of the load resistance on the efficiency. The optimum load condition for the inductive links is ...
The global public good of climate stabilization, pursued in the negotiations leading up to the Kyoto Protocol, provides a useful case study of the political problems that can arise in attempts to reconcile structural or procedural aspects of justice and fa ...
The present study investigates the oxidation of methyl tert-butyl ether (MTBE) by conventional ozonation and the advanced oxidation process (AOP) ozone/hydrogen peroxide under drinking water treatment conditions. The major degradation products identified w ...
Ozonation of bromide-containing waters causes the formation of bromate which is considered to be potentially carcinogenic. An investigation in Switzerland on water works using ozone (85) has shown that the new drinking water standard of 10 mug/L for bromat ...
