ResumoDissolved air flotation technology is the most efficient and economical solution for the treatment of industrial effluents, using biosurfactants to replace chemical surfactants, due to the tensoactive properties, greater stability and biodegradability. The present work aims to present an efficient solution through the new DAF technology, configured in the Induced Saturation Tower (IST) in stages, in bench scale. To increase the efficiency of the process, an anionic polymer as flocculating and a microbial biosurfactant was used in the treatment of oily effluents. In this sense, the potential of the biosurfactant produced by Pseudomonas cepacia CCT6659, cultivated in an economic culture medium composed of industrial waste, as alternative collector, was evaluated.
