Title (EN) ELEMENTAL SULFUR-BASED MIXOTROPHIC DENITRIFYING MEMBRANE BIOREACTOR
(FR) BIORÉACTEUR À MEMBRANE DE DÉNITRIFICATION MIXOTROPHE À BASE DE SOUFRE ÉLÉMENTAIRE
Abstract:
(EN) The present invention is concerned with the development of a system for the simultaneous nitrate and chromate reduction by combining the advantages of sulfur-based autotrophic denitrification heterotrophic denitrification and membranebioreactor (MBR) technologies. The invention has been especially applied to eliminate the disadvantages of heterotrophic denitrification and sulfur-based autotrophic denitrification with the mixotrophic process which it is a method for the reduction of nitrate and Cr (VI). Through the invention, the produced sulfate in the sulfur-based autotrophic denitrification below the limit values and the alkalinity requirement was eliminate by means of the alkalinity produced in the heterotrophic denitrification process. In addition, thanks to the membrane (8) used in the system, microorganisms with slow growth rate keeps in the bioreactor (7). At the same time, the wash away of small particle size materials from the system was prevented.
(FR) La présente invention concerne l'élaboration d'un système pour la réduction simultanée de nitrate et de chromate en combinant les avantages des technologies de dénitrification hétérotrophe à base de soufre, de dénitrification autotrophe et de bioréacteur à membrane (MBR). L'invention a été spécialement conçue pour éliminer les inconvénients de la dénitrification hétérotrophe à base de soufre et de la dénitrification autotrophe avec le procédé mixotrophe qui est un procédé de réduction du nitrate et du Cr (VI). Avec cette invention, le sulfate produit dans la dénitrification autotrophe à base de soufre au-dessous des valeurs limites et l'exigence d'alcalinité ont été éliminées grâce à l'alcalinité produite par le processus de dénitrification hétérotrophe. De plus, grâce à la membrane (8) utilisée dans le système, les microorganismes à taux de croissance lent demeurent dans le bioréacteur (7). Parallèlement, le lessivage des particules de petite taille du système est évité.
