Title (EN) A PROCESS FOR TREATING WASTEWATER COMPRISING TREATING SLUDGE WITH HYDROLYTIC ENZYMES
(FR) PROCÉDÉ DE TRAITEMENT D'EAUX USÉES COMPRENANT LE TRAITEMENT DE BOUES AVEC DES ENZYMES HYDROLYTIQUES
Abstract:
(EN) Methods are provided for reducing or eliminating the amount of exogenous carbon sources added to wastewater or sludge thereof by the addition of a hydrolytic enzyme to primary or secondary sludge of wastewater wherein said hydrolytic enzyme enhances the hydrolysis and subsequent fermentation of the sludge, thereby generating more carbon sources in situ.
(FR) L'invention concerne des procédés de réduction ou d'élimination de la quantité de sources exogènes de carbone ajoutées à des eaux usées ou à leurs boues par l'addition d'une enzyme hydrolytique à des boues d'eaux usées primaires ou secondaires, ladite enzyme hydrolytique améliorant l'hydrolyse et la fermentation ultérieure des boues, générant ainsi davantage de sources de carbone in situ.
