Title (EN) WATER TREATMENT PROCESS
(FR) PROCÉDÉ DE TRAITEMENT DE L’EAU
Abstract:
(EN) The present invention provides a process for treating water which comprises chloride ion, oxidizable ion, suspended solids, and ion reducing bacteria, said process comprising oxidizing an oxidizable ion to produce an oxidized ion, wherein the oxidizable ion comprises ferrous ion, sulfide ion, sulfite ion, or a mixture thereof, reducing the amount of ion reducing bacteria to produce a substantially ion reducing bacteria free water, wherein the ion reducing bacteria comprises iron reducing bacteria, sulfur reducing bacteria, or a mixture thereof, subjecting the substantially ion reducing bacteria free water to conditions sufficient to precipitate suspended solids, and separating at least a substantial portion of the precipitated suspended solids from the substantially ion reducing bacteria free water to produce a treated water.
(FR) L’invention concerne un procédé de traitement de l’eau comprenant un ion chlorure, un ion oxydable, des solides en suspension, et des bactéries réductrices d’ion. Ledit procédé consiste à : oxyder un ion oxydable pour produire un ion oxydé, l’ion oxydable comprenant un ion ferreux, un ion sulfure, un ion sulfite, ou un mélange de ceux-ci, ce qui permet de réduire les bactéries réductrices d’ion pour produire de l’eau sensiblement exempte de bactéries réductrices d’ion, ces dernières comprenant des bactéries réductrices de fer, des bactéries réductrices de soufre, ou un mélange de celles-ci; soumettre l’eau sensiblement exempte de bactéries réductrices d’ion à des conditions suffisantes pour précipiter les solides en suspension, et séparer au moins une partie substantielle des solides en suspension précipités provenant de l’eau sensiblement exempte de bactéries réductrices d’ion afin de produire de l’eau traitée.
