After presenting the method developed for simulating a repeatable manual dishwashing process, the report shows the results of the experimental study exploring the main impact factors for the optimization of the water consumption by applying a mathematical regression model. These experiments demonstrate that the water changes in the main washing bath and the water changes in the rinsing bath are significantly affecting the cleaning performance of the dishes. Concentration of cleanser is found to have a negative quadratic effect, and the interaction effect of the number of water changes in the rinsing bath with the amount of detergent (respectively Concentration of cleanser) is found to be significant. As an explanation of this behaviour, it is suspected that soil particles are transferred through foam residuals, which are not washed off in the rinsing bath. Because of several restrictions, such as having limited statistics and having excluded possible impact factors, the developed model aims at depicting tendencies of the impact factor effects and may not be generalized.

Resource saving by training – how much can be saved in manual dishwashing ? / Natalie Fuss in TENSIDE, SURFACTANTS, DETERGENTS, Vol. 48, N° 5 (09-10/2011)

Type de document : texte imprimé Auteurs : Natalie Fuss, Auteur ; Rainer Stamminger, Auteur Année de publication : 2011 Article en page(s) : p. 359-365 Note générale : Bibliogr. Langues : Anglais (eng) Tags : 'Lavage  vaisselle'  'Consommation  eau  optimale'  'Economie  eau' Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Automatic dishwashing has been optimised in manifold ways during the last decades. But it is also necessary to optimise manual dishwashing, because almost every household still washes up at least a few items by hand. A procedure based on an experimental multi-factorial laboratory study was developed to wash up a specified number of dishes with good cleanliness and an optimum water consumption as results. This procedure was then translated into generalised dishwashing tips – called Best Practice Tips. These tips were used to run two comparative consumer laboratory studies: the first part of each study investigated the everyday dishwashing behaviour and resource consumption of consumers. The second part studied the behaviour and the resource consumption after a training on the Best Practice Tips. The comparison showed that with a larger number of dishes, relevant amounts of resources of energy and water can be saved, whereas with a smaller number of dishes, no significant reduction was found. This is possibly due to a different optimum for washing up only a few items. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=12549 [article]
