Abstract: A process for the treatment of wastewater, commonly known as nejayote, from the nixtamal, masa and tortilla industry, having an improved method for removing the insoluble fraction and a filtration system for separating and concentrating the fractions forming the nejayote is described. The method includes the steps of: (a) neutralizing the nejayote; (b) enzymatically hydrolyzing the starch granules; and (c) flocculating and separating the insoluble fraction. The system includes the steps of (a) microfiltration; (b) ultrafiltration for concentrating long-chain carbohydrates; (c) ultra/nano filtration for concentrating medium-size compounds; and (d) nanofiltration/reverse osmosis for concentrating small molecules and obtaining water of sufficient quality that it can be re-used or safely discharged into the environment. In one embodiment of the invention, in order to remove unwanted phenolic compounds, the process includes a method including the steps of: (a) acidifying the effluents at pH

Abstract: An anaerobic digestion system is provided that includes a blend tank operable to control and perform pre-treatment of feedstock. An anaerobic digester is operable to digest the feedstock provided from the blend tank in a totally enclosed oxygen-free environment within a specific temperature range. A bio-mass tank processes liquid digestate from the anaerobic digester. One or more baffles are positioned in the digester, with the one or more baffles providing for plug flow through at least a portion of the digester to create baffled zones that are at least partially operable independently of adjacent baffled zones. A bio-mass tank processes liquid digestate from the anaerobic digester. An energy source is coupled to the anaerobic digester.

Abstract: A portable renewable energy microgeneration system is disclosed. The system comprises one or more holding tanks that are configured to perform anaerobic digestion on waste in a multi-phase process using bacteria and a controller configured to automatically control the multi-phase process and to re-use the bacteria. The controller re-uses the bacteria by removing at least a portion of the liquid from the waste after anaerobic digestion is performed on the waste and using the at least a portion of the liquid to wet other waste and repeat the multi-phase process.

Abstract: Feed water is processed in an anaerobic digester. A solid-liquid separation device, for example a sludge screw thickener, treats a stream drawn from the digester in a recirculation loop. The solids portion is returned to the digester to increase the solids retention time and the TSS concentration in the digester. A liquid portion with less than 5% of the solids in the stream is removed and optionally treated further. The flow rate to the solid-liquid separation device is preferably greater than the influent flow rate. The solid-liquid separation device may receive digestate at a TSS concentration of 4% or more and return a solids portion having a TSS concentration of over 10%. The feed water is preferably one or more industrial waste streams having a COD concentration of 20,000 to 50,000 mg/L and a TSS concentration from 1-5%. The organic loading rate may be 10-12 kg/COD/m3/day.
