5 Factors You Should Consider When Designing a Biogas Unit

With the constant rise of technology and the waste that is being produced that pollutes our planet, we are obliged to look for alternative fuel solutions. Although the existing ones are constantly being improved to prevent pollution, they are not reusable.

There have been scientific discoveries of biogas units, that are turning regular plant waste into methane gas. This matter can be used in various industries and everyday situations. These features make biogas a project from the future, that will surely be useful for everyone.

Besides the protection of our planet, turning waste into gas has financial benefits as well. That way, the industries can be run more efficiently, coming up with more affordable products for everyone. When you plan on designing a biogas unit, there are a few factors that you should consider. For that purpose, we have created this article showing these factors, both for educational, and future business move purposes.

1. Make sure the site offers high flexibility standards

As a relatively new source of renewable energy, the biogas unit will be under constant developing process. This means that in the future, you must be able to adapt to the equipment that you already possess. Since many of these developments can already be predicted, you should plan your biogas designing project to adjust quickly. These possible adjustments are essential for the longevity of the business, so they must be done properly.

It is known that the designing of these units is already done according to the site and the requirements that the clients have. However, making sure about its longevity, and the ability to transform its place in the future for better efficiency is highly important.

These flexibility standards will help the business adapt to future changes and market demands, which shows their importance.

2. Getting right equipment

The equipment is the most important aspect of running a biogas unit. For every step, you need special machines that contribute to preparing the feedstock for the next stage. You will need full control over the machines, to ensure efficiency through the crops being well prepared.

Keeping the digester unit working properly requires special maintenance methods. This means that you will need to adjust the dosing and change the crops on time for bigger efficiency. You will need additional efforts to keep the machines running without producing too much solid waste, and the need for chemical oxygen.

A proper biogas dome is also essential. A dome that can endure high amounts of pressure and that can be deployed in a large diameter for increased storage as the ones found on biogasmembrane.com.

There are special devices that fire up a whole system to work automatically whenever you have variations in the gas pressure.

By implementing a system that lets you supervise and control the whole process, you are dramatically improving your biogas plant effectiveness.

3. Keeping the right temperature standards

As in all other machinery, the temperature needs to be well adjusted and constant in the biogas units. This is important for the longevity of the machines since they work the best at their appropriate working temperature. On the other hand, the right temperature is essential for the feedstock to decompose and ferment on its own while producing the highest amount of methane possible.

That is why you need to observe the temperature stats on your digester. Every machine has its features that need to be adjusted, so make sure you set up the right thermal and ensure its stability. This can be done by using sensors and alarms whenever the temperature falls or rises from its constant.

4. Take care of the energy usage

To earn more, you need to track the electricity usage that your factory produces. However, many machines are essential for the plant and they usually consume most of the energy. That is why you need to find a way how to use them more effectively and prevent losses. That way, you will keep on producing gas, while keeping the electricity costs at a minimum.

A great method that you should implement in your plant is coming up with a strategic plan for decreasing electrical usage. This can include tracking the amount of waste you have processed, and the annual electricity goal. By staying close to these parameters, the efficiency will surely grow. In addition, you can track the parameters of energy used versus the energy you have produced. Staying in a positive surplus is an indicator of your efficiency.

Keep in mind that this plan will require regular adjustments, for the purpose of running a plant that is more efficient than the others.

5. Implementing control systems and automation

Ensuring that everything runs properly at all times is an essential factor to consider when designing a biogas unit. Because the machines are constantly running, you will need to track certain stats and react accordingly if necessary.

There are many systems that have been made to control your biogas unit. They are even available for your smartphone, so you can observe everything wherever you go. This software also identifies major problems like leaks for example. Tracking all of the parameters, and having them recorded for further analysis is essential for controlling your business.

In addition, these machines work by using pressured canisters and vessels where the gasses go through. This is a portion of high importance that needs to be constantly observed and controlled. By implementing a valve system for pressure releasing you have further control over the biogas unit. It also writes and records any activities out of the ordinary, so you can react on time, or predict fluctuations in the future.


Working with a technology that is relatively new has its own good and bad sides. That is why you will need additional effort to ensure that your biogas unit works properly and most efficiently. This can be only done with great preparation and planning. However, keep in mind that there will be constant upgrades and development in this field, so you will need to adjust things properly in the future. By combining these factors, with the request from the clients, you should be on the right way to designing great biogas units.
