Treating wastewater


Lyonnaise des Eaux (ONDEO), one of France’s largest water treatment companies, has patented a new low-tech technique to treat domestic wastewater. Its first application in France is the small township of Neuvy-Bouin, which has 150 inhabitants. Rhizopur combines two already known processes not previously used together—a bacterial bed followed by reed filter beds, or rhizofilters. The first stage provides treatment of dissolved and colloidal carbonaceous matter on a bacterial bed.
