Title
(EN) MULTI-COLUMN CONTINUOUS RESIN REGENERATION SYSTEM
(FR) SYSTÈME DE RÉGÉNÉRATION DE RÉSINE CONTINUE À COLONNES MULTIPLES
Abstract
(EN) A continuous resin regeneration system (10) includes a process by which resin in need of being recharged is continuously recharged and cleaned with a plurality of two-set filtration columns (20, 30, 40) so that resin regeneration and the flow of influent is continuous and interrupted. Downstream filtration columns (20', 30', 40') also undergo this cycling but at slower and related rates as the first column with the dirtiest water will naturally degrade resin faster than the downstream columns. Contaminated influent is cleaned by the continuously recharged resin in multiple column sets. The degree of cleaning of earlier filtration columns affects the resin flow rate of later filtration columns.
(FR) L'invention concerne un système de régénération de résine continue (10) comprend un processus par lequel la résine ayant besoin d'être rechargée est rechargée en continu et nettoyée avec une pluralité de colonnes de filtration à deux ensembles (20, 30, 40) de telle sorte que la régénération de résine et l'écoulement d'influent sont continus et interrompus. Des colonnes de filtration en aval (20', 30', 40') subissent également ce cycle mais à des vitesses plus lentes et associées à mesure que la première colonne avec l'eau la plus sale dégradera naturellement de la résine plus rapidement que les colonnes en aval. L'influent contaminé est nettoyé par la résine rechargée en continu dans de multiples ensembles de colonnes. Le degré de nettoyage des colonnes de filtration précédentes affecte le débit de résine de colonnes de filtration ultérieures.
