The present invention refers to a method for increasing the concentration of colonies of micro organisms formed on the surface of Gramineas bambusoideae in a continuous flow and/or batch process which utilizes biomass as a filtering means to remove nitrates and other organic and inorganic contaminants from water reservoirs and from domestic and/or industrial effluents, in which a step of adsorption is followed by a step of biological degradation by anaerobic digestion of micro organisms of the types Pse?donomas SP (Azobacter, Azotomas, Nitrosomonas, Nitrosococus, Nitrobacter, and Rhixobium). According to the invention, the addition of about 200 - 300 ppm of sodium acetate to the solution fed to the reactor, while maintaining a relation of 2:1 C:N, provides an efficiency increase of 80% to 98% regarding the removal of nitrates as well as organic and inorganic soluble matter from the water. |
