Title
(EN) BIOREMEDIATION SYSTEMS FOR WASTEWATER TREATMENT AND METHODS FOR THE USE THEREOF
(FR) SYSTÈMES DE BIOREMÉDIATION POUR TRAITEMENT DES EAUX USÉES ET PROCÉDÉS POUR LEUR UTILISATION
Abstract
(EN) The present disclosure relates to bioremediation systems and methods for wastewater treatment in heavy industry, including the mining industry. A benefit of the systems and methods disclosed herein can include the reduction of heavy metals in wastewater. Another benefit can be the treatment of acidic wastewater to achieve higher pH levels. An additional benefit can be the use of carbon dioxide to raise the pH level of acidic wastewater, or to produce feedstocks for the growth of anaerobic or aerobic microorganisms that are capable of reducing a concentration of heavy metals in wastewater. A benefit of the systems and methods herein can include the treatment of acid mining drainage wastewater, as well as heavy metal removal from other industrial wastewater. Another benefit of the methods and systems disclosed herein can include reduction of excess carbon dioxide from the environment.
(FR) La présente invention concerne des systèmes et des procédés de bioremédiation pour le traitement des eaux usées dans l'industrie lourde, y compris l'industrie minière. Un avantage des systèmes et procédés de l'invention peut inclure la réduction des métaux lourds dans les eaux usées. Un autre avantage peut être le traitement des eaux usées acides pour obtenir des taux de pH plus élevés. Un avantage supplémentaire peut être l'utilisation du dioxyde de carbone pour augmenter le taux de pH des eaux usées acides, ou pour produire des matières premières pour la croissance de micro-organismes anaérobies ou aérobies pouvant réduire la concentration de métaux lourds dans les eaux usées. Les systèmes et procédés de l'invention peuvent notamment servir à traiter les eaux usées de drainage minier acide, ainsi qu'à éliminer les métaux lourds d'autres eaux usées industrielles. Un autre avantage des procédés et systèmes de l'invention peut inclure la réduction de l'excès de dioxyde de carbone dans l'environnement.
