(FR) INSTALLATION OU ÉQUIPEMENT DE TRAITEMENT COMPRENANT UN ARTICLE AVEC UN REVÊTEMENT PERMETTANT D'INHIBER LES DÉPÔTS DE STRUVITE, ET PROCÉDÉ DE FABRICATION ET D'UTILISATION DE CELUI-CI
Abstract:
(EN) A manure, landfill leachate, sewage and/or wastewater treatment plant, treatment equipment or downstream conveying equipment, such as a manure, sewage and/or wastewater treatment plant comprising one or more biological treatment reactors, where said treatment plant or equipment comprises at least one component, wherein the at least one component and/or the at least one or more reactors or a drain of the treatment plant or equipment comprise at least one surface, which is exposed to a sus- pension comprising struvite particulates or colloids or to a supersaturated struvite so- lution, and where said reactor(s), pipes and/or said component is coated with a coat- ing, said coating being applied to at least a part of said surface exposed to the struvite containing suspension or supersaturated solution. The coating is preferably prepared using organosilanes. The coating is applied by a method comprising the steps of (i) preparing a liquid coating composition, (ii) applying said liquid coating composition to at least part of the surface of an article and (iii) curing to form solid coating film on said article. The coating reduces or eliminates formation of struvite deposits on the coated surface arising from a suspension of struvite particles or from a supersaturated struvite com- position.
(FR) L'invention concerne une installation de traitement, un équipement de traitement ou un équipement de transport en aval, de fumier, de lixiviat de décharge, d'égout et/ou d'eaux usées tel qu'une installation de traitement de fumier, de lixiviat de décharge, d'égout et/ou d'eaux usées comprenant un ou plusieurs réacteurs de traitement biologique, où ledit équipement ou installation de traitement comprend au moins un composant, ledit au moins un composant et/ou ledit ou lesdits réacteurs ou une évacuation de l'équipement ou installation de traitement comprend au moins une surface, qui est exposée à une suspension comprenant des matières particulaires ou colloïde de struvite ou à une solution sursaturée de struvite, et où le(s)dit(s) réacteur(s), le tuyau et/ou ledit composant sont revêtus d'un revêtement, ledit revêtement étant appliqué à au moins une partie de ladite surface exposée à la suspension ou solution sursaturée contenant de la struvite. Le revêtement est de préférence préparé à l'aide d'organosilanes. Le revêtement est appliqué par un procédé comprenant les étapes consistant à (i) préparer une composition de revêtement liquide, (ii) appliquer ladite composition de revêtement liquide sur au moins une partie de la surface d'un article et (iii) durcir pour former un film de revêtement solide sur ledit article. Le revêtement réduit ou élimine la formation de dépôts de struvite sur la surface revêtue, découlant d'une suspension de particules de struvite ou d'une composition sursaturée de struvite.
