Bioremidation of industrial waste water by using azolla

Bioremediation is process which employs the use of living organisms such as microbes & bacteria as a remedy for solving environmental problems. It confers the decontamination of affected areas. It is used in the removal of contaminants, pollutants. The current project studies Bioremediation of petroleum industry waste water by using Azolla. Azolla is an aquatic fern commonly known as mosquito fern. In this project, the Azolla plant was allowed to grow in industrial waste water. The various physical & chemical parameters of waste water before & after Azolla treatment showed significant changes that help to conclude that Azolla seems to be an ecofriendly approach to treat the industrial waste water. It will be considered as the better method for bioremediation to prevent water pollution
