Chattez avec Graph Search
Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.
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.
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 ...
The electrochem. behavior of a synthetic B-doped diamond thin film electrode (BDD) was studied in acid media contg. phenol using cyclic voltammetry and bulk electrolysis. In the potential region of H2O stability direct electron transfers can occur on BDD s ...
Industrial applications of supply chain cost management, along with life cycle costing of goods and services, are increasing. Several industrial sectors, in particular the automotive, electronics, and primary materials, have engaged in programs to coordina ...
A combined chemical-biological treatment of industrial wastewater using ozonation as the first step of a Sequencing Batch Biofilm Reactor (SBBR) process, in which 3-methylpyridine (3MEP) was degraded as a model industrial pollutant, has been developed. The ...
The controlled biodegradation of ametryn and methomyl has been performed, in accordance with the OECD Zahn-Wellens/EMPA procedure, by use of an enriched mixture of activated sludge collected from three domestic waste-water-treatment plants (WWTP). During t ...
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 ...
A promising elimination treatment of non-biodegradable org. pollutants is the direct electro-oxidn. The electrochem. elimination of polyacrylates by using B-doped diamond as anodic material was proposed. The complete elimination of org. contaminants was ob ...
This research contributes to the study and development of a new degradation technique that couples solar and biological processes for the treatment of biorecalcitrant, nonbiodegradable, and/or toxic organic substances present in the aqueous medium. Efficie ...
A high mol. wt. water sol. acrylamide based polymer having improved flocculating properties is provided. The polymer is prepd. by a process, in which a small quantity of a chain branching agent such as methylenebisacrylamide is added to the polymn. reactio ...
The electrochem. behavior of PbO2 and synthetic B-doped diamond thin film electrodes (BDDs) was studied in acid media contg. 4-chlorophenol (4-CP) by bulk electrolysis under different exptl. conditions. To quantify the electrochem. activity of a given elec ...
