The present invention refers to a process to increase the concentration of micro organisms' colonies which are formed on the surface of Gramineas bambusoideae in a batch and/or continuous flow process which utilizes biomass as a filtration means in order to remove nitrates as well as organic and inorganic impurities from water and/or from affluents in which a step of adsorption is followed by a step of biological degradation by the anaerobic digestion of micro organisms of the types Pseudonomas SP (Nitrosomonas, Nitrosococus, Nitrobacter, Azobacter, Azotomas and Rhixobium). In accordance to the present invention, the addition of about 200-300 ppm of sodium acetate to the solution fed to the reactor, maintaining a relation of 2:1, C:N, provides an efficiency increase of 80% to 98% regarding the removal of nitrate as well as organic and inorganic soluble matter from the water. |
