The excess energy can be sold back to the grid for profit. The anaerobic wastewater treatment system has been known and used since the end of the 19th century [4]. It is during this period, that the intermediate products of fermentation in other words, acid carbonates and ammonia compounds, accumulate and the resulting gasification into H2 and CO2 is at a minimum. Anaerobic digestion is a biological process in which organic wastes are broken down by microorganisms in the absence of oxygen. Systematic research work and deeper anaerobic process understanding caused anaerobic digestion (AD), a biological process in which organic matter is converted to CH4 and CO2, to become a As the anaerobes in the sludge digest the organic constituents in the wastewater, they multiply and collect into larger granules that settle to the bottom of the reactor tank, and can be recycled for future cycles. A range of anaerobic digestion technologies are converting livestock manure, municipal wastewater solids, food waste, high strength industrial wastewater and residuals, fats, oils and grease (FOG), and various other organic waste streams into biogas, 24 hours a day, 7 days a week. The flow rate is then balanced with the geometry of the tank so that a “blanket” of sludge, which is particles of organic matter and bacteria constantly falling gently in the water at the same speed as the water rises, stays perpetually suspended. The extent to which the blanket is truly anaerobic can be questionable. In this stage, the organic acids and nitrogenous compounds of the first stage are liquefied i.e., transformed from large solid particles to either a soluble or finely dissolved form. Green energy this way using WASTE is good for the environment I am sure. You are welcome to come to our web site in Pinterest, which we hope can give you info and lots of inspiration for the biogas.
