You probably have heard a word or two about a biogas digester, but you are not sure what it means and how it can help you. Also referred to as a biogas plant, the digester is a large tank intended to produce biogas via the natural breakdown or decomposition of organic matter. The process involved in breaking down the organic matter is known as anaerobic digestion. The reason why it is called a digester is that the organic matter is eaten and digested by bacteria, thereby producing the biogas in the process. The biogas digester is necessarily the most crucial aspect of the production of biogas. Without it, there is no other useful and practical way of breaking down organic material.
The production of biogas naturally occurs during the break down of biodegradable and organic waste. In many parts of the world, they refer to waste as “biomass.” The examples of natural materials or waste used in the production of biogas like in Ambisense – BioGasSystems.com.au include that of grass, weeds, leftover food, leaves, vegetables, and others. The breakdown of these materials produces biogas.
Biogas is a product of methane and carbon dioxide, and when you smell it, it is like liquid petroleum gas. Similar to natural gas, biogas may also be utilised as fuel to produce power or electricity. Many establishments in the country like farms use it for different applications, including but not limited to lighting, cooking, and transportation.
Today, biogas is rapidly becoming a mainstream source of power and a practical alternative to natural gas and other fossil fuels. In Australia, there is emerging technology like Ambisense – BioGasSystems.com.au that encourage commercial, industrial, as well as domestic production and use of biogas.
The biogas digester is the focal point of biogas production, and it comes with a handful of components that play crucial roles. But first, you should know that the digester is a part of a large biogas electric generator plant. The conventional biogas digester has a container used for holding both organic waste and water. The term given to the combination of both materials is slurry. There usually is another tank in the digester that contains the gas produced after breaking down the organic material. Aside from that, you also will see several connections that use pipes, the purpose of which is to feed the digester with slurry and then connect the container with the manure in it to the tank with the gas. The digester comes with a transport system that takes biogas to its destination, and it is the final step of the process.
Finally, you should know that while biogas digesters are a standard tool in farms, you also see them in homes and urban areas these days. The increasing popularity of biogas is no surprise considering how efficient and cost-effective it is, as compared to other sources.
