  • Process to anaerobic digestion of wastewater with high concentration of ammonia nitrogen or protein, in upflow anaerobic digester and sludge blanket, with immobilization of microorganisms and inhibition by ammonium controlled using zeolite-clinoptilolite, and optional production of biofertilizer
    Patent number: 9422179
    Abstract: Procedure using zeolite, clinoptilolite type in an upflow anaerobic reactor and sludge blanket (UASBs) in order to obtain granular active sludge, thereby improving the density of the sludge, and thereby, their settling properties, and increase of biomass within reactor by immobilizing microorganisms, to achieve an increase in the efficiency of the removal of organic material and the production of biogas (60-70% methane) in more than 20% over the same type reactor used so far without zeolite, enabling the use of such reactor for treating wastewater with a high concentration of proteins, amino acids and other nitrogen compounds and which prevents the accumulation of nitrogen, which is toxic to the process by allowing zeolite-clinoptilolite, the exchange with alkali and alkaline earth found in specific points of the crystal structure of clinoptilolite by ammonia nitrogen, and also preventing the development of filamentous bacteria, which are difficult to hold up within the reactor and reduces its efficiency.
