About the Book

Le souci et la demande d'un traitement approprié des effluents générés par les processus les plus divers découlant des activités anthropogéniques ne sont pas nouveaux de nos jours, et ne cessent de croître. Parmi les coagulants chimiques les plus couramment utilisés figurent le sulfate d'aluminium, le chlorure ferrique, l'hydroxychlorure d'aluminium et le sulfate ferrique. Ces coagulants utilisés dans le processus primaire sont responsables de l'élimination d'environ 60 % de la matière organique (SCHUCK, 2011), des micro-organismes et d'autres substances présentes dans l'effluent. Ces dernières années, des alternatives naturelles sans la composition métallique des coagulants traditionnels ont été recherchées pour éliminer la matière organique. Parmi ces alternatives, le tanin, décrit par Cruz (2004) comme un polymère naturel de plus en plus utilisé, obtenu à partir de l'extrait de l'acacia noir (Acacia mearnsii). L'utilisation de ces coagulants/floculants dépend des caractéristiques physiques de chaque effluent analysé, principalement en ce qui concerne la teneur en solides et le volume de boues généré dans la station d'épuration des effluents (LORA, 2002).
