The process of using this reactor is straightforward and does not require a lot of energy. First of all, make sure the building’s entire construction is airtight, and the ducts connecting the fixed-dome with the collection of dirt and other organic matter are ready to function correctly.
Before starting to use it, make sure the reactor is clean of residual building materials. For parts outside the reactor, compact it with soil. Also, biogas users need to plan rainwater drains around the biogas. This must be done to prevent rainwater from entering the reactor.
How the Fixed-Dome Biogas Reactor Works
When the entire reactor building is ready, it must be immediately filled with manure. All manure (livestock and humans) and organic material are collected into the mixing tank (inlet). This mixture of dirt and organic material will travel to the digester through the inlet pipe. This inlet pipe can be modified to be connected directly to the toilet if you want to use human waste as raw material for the biogas reactor. In the digester, all energy raw materials are processed to produce gas.
All gas will be accommodated at the top of the concrete dome (fixed-dome). If the gas pressure is full, the gas will automatically flow to the houses through the main gas pipe. All these impurities and organic materials will have flowed to the outlet through the outlet overflow in the same process. The waste that comes out of this process is known as bio-slurry.
In the form of bio-slurry, waste can be used as a natural fertilizer. It can even become one of the potential additional income for biogas users for urban farming/agriculture or sale. The fire and energy generated from this biogas process have a high enough heat; the flames are blue, odorless, and smokeless.
How To Fill the Reactor with the Dirt
The amount of animal manure is determined by the size of the biogas reactor. The ratio for mixing animal manure and water on a daily basis is 1: 1. For the better result of fermentation, add bio-slurry in the first use. Because bio-slurry can help the process of seeding bacteria in the reactor.
To operate the biogas reactor, put a mixture of manure and water into the inlet. Mix well and make sure all valves are open so that when the manhole is full, the reactor is ready to work to produce methane gas (biogas). For the first filling, animal manure must be fresh so that it has a lot of bacteria. For maximum results, it is recommended to mix it with bio-slurry for the better fermentation.
