SAITA - Model IWT Series -Zero Liquid Discarge for Photovoltaic Solar Cells Production

Integrated system for the closed circuit treatment of process water deriving from the production of photovoltaic cells. The IWT (Integrated Waste water Treatment) Series system is a closed circuit treatment system, integrated with the production line of multicrystalline silicon cells, that allows recovering 97% of the treated water. The IWT process, started in 2008, is designed to treat any type of waste water generated by the silicon cell production line. Passing through various treatment phases in the IWT system, the discharged water becomes progressively purer and can be reused to supply the photovoltaic cell production systems. The only waste produced by the whole system is an inert solid sludge.
