Understanding Anaerobic DigestionAnaerobic digestion is the process through which waste items such as food waste, animal waste, etc., can be converted into renewable and reusable energy.

This process is widely used to generate energy and protect the Earth, as well as the ozone layer from further harm and damage.

There are various methods through which anaerobic digestion is conducted. These methods do not always take place through an anaerobic digester, because anaerobic digestion can take place naturally within certain types of soils, lakes and oceans, in which case it is called ‘anaerobic activity’. However, this is rarely ever the case which is why scientists have introduced anaerobic digesters to help generate energy by recycling waste items.

One of the most notable things about anaerobic digestion is that it lessens and almost diminishes the strong and intolerably horrid odor that is secreted from waste products when they are in the process of decomposing. This is also a form of preserving the Earth’s natural elements and protecting it from damage and harm in the future.

Types of Anaerobic Digesters

Nevertheless, there are various types of anaerobic digesters that are used for the purpose of generating fresh energy by recycling waste items. 3 of the best types of anaerobic digester vessels include:

1.      Dry Digester

Dry Digester

Dry anaerobic digesters run at a maximum of 42% complete solids. This permits these digesters to create a combination of crop remnants and high dry matter manure with co-substrates and liquid manures. Dry digesters are made out of steel and concrete with firm and stiff cover.

2.      Covered Lagoon Digester

Covered Lagoon Digester

This type of anaerobic digester is mostly used as a single cell for digestion and is carefully sealed with a cover that is flexible and built to suit supplemental heat. Covered lagoon digesters are mostly not used for storage purposes and comprise of elevated dilution features and extensive preservation periods.

3.      Complete Mix Digester

These types of digesters are made specifically to suit the excretions of things such as manure and water.

Complete mix digesters are protected and are supposed to be kept and taken care of under a stable and high temperature.

These types of digester vessels are made mostly from fiberglass, concrete or steel.

 


There are many different kinds of anaerobic digesters through which anaerobic digestion takes place, but these are the top three most commonly used anaerobic digester vessels to carry forth the process.


Benefits of Anaerobic Digestion

Recycling Process of Food WasteAlthough anaerobic digestion is a procedure used mainly for recycling, it has many benefits and has a major influence on our nature and surroundings, as well as the health of the planet. The benefits of using anaerobic digestion and digester vessels in the local area are that they help reduce the awful smell of odor and work to eliminate fly eggs.

The regional impact of anaerobic digestion is that it manages to reduce pathogen significantly of nutrients grown on land, and provides support for electricity and voltage in rural areas. The global benefits of anaerobic digestion are the significant amount of reduction greenhouse gases secretions, such as methane. Also, anaerobic digestion causes a major decrease in fossil fuel dependency.

So there you have it, a guide to understanding anaerobic digestion and its multiple benefits.
