Detailed explanation-1: -Anaerobic digestion is a process through which bacteria break down organic matter-such as animal manure, wastewater biosolids, and food wastes-in the absence of oxygen.
Detailed explanation-2: -Anaerobic Decomposition, or Anaerobic Digestion, is Renewable Energy technology, where organic materials are placed in a container and are broken down by microorganisms to create Biogas.
Detailed explanation-3: -Basically, an anaerobic treatment cycle involves wastewater entering a bioreactor receptacle containing a thick semi-solid substance called sludge, full of anaerobic bacteria and other microorganisms which break down the organic contaminants present in the wastewater.
Detailed explanation-4: -Biogas is generated during anaerobic digestion when microorganisms break down (eat) organic materials in the absence of air (or oxygen). Biogas is mostly methane (CH4) and carbon dioxide (CO2), with very small amounts of water vapor and other gases.
Detailed explanation-5: -It’s a Biological Process, and there are 4 stages: Hydrolysis, Acidogenesis, Acetogenesis, Methanogenesis. Hydrolysis-the first step in the conversion of organic material to biogas.
