Abstract: Phytoremediation of industrial effluents by aquatic plants.
The industrial effluents treatment must be carried out to the point where they can be discharged into the bodies of water without causing damage at local environment according to the local rules. In this context, the use of biosolutions has been growing because it is a cheap and biodegradabel technology. This project aimed at the post treatment of industrial effluents soybean oil indutsry through the implementation of aquatic plants macrophytes of the genus Eichhornia crassipes by confined islands for removal the load and nutrients. Macrophytes were implanted in confined islands in a lagoon and aerobic filters, and the results were satisfactory in terms of load removal. In this case reduced from 52,42 ppm, over the rules to 35,50 ppm in according with the rules where the limit is 50 ppm. The use phytiremediation becomes a viable and envioronmentally correct alternative for the treatment os industrial effluents. By the way is possible to produce second generetion ethanol from removed plants, where in an experiment was obteined alcohol with 78% purity.
