Rhitala, India

 

Thanks to advanced technologies (wastewater treatment through biofiltration, sludge treatment through dissolved air flotation), the plant achieves high discharge standards. Furthermore, the Rithala plant is operated on a self-sustainability basis in terms of energy requirements. The plant was commissioned in September 2002, and has been operated by Degrémont since April 2003.
