Biological treatment is a process in which the pollutants in the waste water(organic matters) are stabilized by microorganisms in the absence of molecular oxygen. Anaerobic microbes are bacteria and microorganisms that function in the absence of oxygen. These microbes break down organic contaminants more slowly than aerobic microbes. Anaerobic microbes produce methane, carbon dioxide and more anaerobic microbes. Wastewater, which contains a high level of organic contaminants, is more efficiently treated with anaerobic microbes before undergoing treatment with aerobic microbes. Anaerobic treatment process converts about 40% to 60% of the organic solids to methane (CH4) and carbon dioxide (CO2).
The chemical composition of the gas is 60-65% methane, 30-35% carbon dioxide, plus small quantities of H2, N2, H2S and H2O. The goal is to reduce the amount of sludge that needs to be disposed. The most widely employed method for sludge treatment is anaerobic digestion. In this process, a large fraction of the organic matter (cells) is broken down into carbon dioxide (CO2) and methane (CH4), and this is accomplished in the absence of oxygen. About half of the amount is then converted into gases, while the remainder is dried and becomes a residual soil-like material.
