Fibria Orders Effluent Systems from Veolia for Horizonte 2 Project

Through its subsidiary Veolia Water Technologies Brazil, Veolia, Paris, France--a specialist in optimized resource management--this past week announced it has been awarded a contract to build three units for demineralized water production, raw water treatment, and effluent treatment at Fibria's (São Paulo, Brazil) new pulp production line located in Três Lagoas in Mato Grosso do Sul, a central western state of Brazil.

Veolia will design and build the three water treatment units using a patented process for each. The first unit will use reverse osmosis and condensate polishing to produce 16,600 cubic meters per day of demineralized water to supply the boilers. The second unit will feature the Actiflo® high-rate clarification process combined with TGV filters to treat 185,000 cubic meters per day of raw water before it is used in the pulp production process.

Finally, the effluents from the pulp plant will go to a third unit where the AnoxKaldnes™ BAS™ process will be used to treat 166,000 cubic meters per day of waste water. This last unit will be designed by Veolia business unit Aquaflow, who is specialized in effluent treatment for the pulp and paper industry.

The effluent treatment plant was designed to comply with the most stringent environmental standards enforced in Mato Grosso do Sul, ensuring that the discharged water meets the highest levels of quality. All three water treatment units are to be equipped with processes known for providing efficient, stable, and robust treatment in a small footprint, reducing construction costs. The opening of the three treatment units is scheduled for the fourth quarter of 2017.
