RESUMO

The discussion about technical, economical and environmental feasibility of water reuse in industrial process has been a constant concern. This thesis purposes a simplified alternative for waste water treatment seeking reuse in a plastic recycle industry. The water, in this case, is a prime component because it is the main element for the debris and impurities removal that contaminates the matrix of the plastic raw material, which comes from, mostly, landfill and waste disposals. The recycled plastic packages, from the company that had been used for this thesis, come mostly from domestic use and, in a minor scale, the plastic package contaminated by lubricant oil. The final results show feasible for the treatment through physicalchemical process by coagulation, flocculation, decantation and filtration on geotextile, with the use of aluminum hidroxichloride (PAC) as coagulant, sodium hydroxide as an alkaliner, polyelectrolyte as a auxiliary on flocculation and slush dehydration, as well as the workability of the effluents reuse under a fully close circuit proved itself the technical, economical and environmental feasibility
