Site Selection Criteria

When selecting a site for the installation of a floating drum type biogas plant, it is crucial to consider several factors to ensure maximum efficiency and effectiveness. The chosen location should have easy access to organic waste sources such as agricultural residues, animal manure, or food waste. Additionally, the site should be relatively close to the end users of the biogas to minimize transportation costs and losses in gas quality.

A stable ground, space for expansion, sunlight exposure, and proximity to water sources are key factors when selecting a site for a floating drum biogas plant installation.

Furthermore, the topography of the site is important, as it should have stable ground to support the weight of the biogas plant and prevent any subsidence. Adequate space for future expansion, good sunlight exposure for the solar heat trap, and proximity to water sources for the periodic cleaning of the plant are also important considerations when selecting a site for the installation of a floating drum type biogas plant.

Step-by-Step Construction Guidelines

Once the site has been selected and surveyed, the construction process for a floating drum type biogas plant typically follows several key steps. Firstly, excavation of the pit for the digester tank is carried out, followed by the placement of a concrete foundation to provide stable support.

A biogas digester is constructed with locally available materials including bricks or concrete and consists of a digester tank, gas outlet and inlet pipes, a floating drum, and an inlet feed pipe connected to a mixing tank.

Next, the gas outlet and inlet pipes are installed, and the digester tank is erected using locally available construction materials such as bricks or concrete. The floating drum is then installed and connected to the gas outlet, and the inlet feed pipe is connected to the mixing tank or feed inlet.

Operational Mechanics of Floating Drum Type Biogas Plants

The Role of the Digestion Chamber

The floating drum biogas plant uses anaerobic digestion to break down organic waste, producing biogas through the growth of bacteria and microorganisms in the digestion chamber.

The floating drum type biogas plant operates based on the anaerobic digestion process, where organic waste is broken down by microorganisms in the absence of oxygen, producing biogas. The digestion chamber is a crucial component where this biological decomposition occurs. Here, the organic material, such as agricultural waste, animal manure, or kitchen waste, is mixed with water, promoting the growth of bacteria and other microorganisms. As these microorganisms break down the organic matter, they release methane and carbon dioxide gases, which then accumulate in the upper part of the digestion chamber.

Movement and Functionality of the Floating Drum

One notable feature of the floating drum type biogas plant is the presence of the floating drum itself, which plays a key role in the functionality of the system. The floating drum, typically made of gas-impermeable material, serves as a gas holder. As the biogas is produced in the digestion chamber, it displaces the water within the drum, causing it to rise. This upward movement of the floating drum creates pressure within the system, allowing for the collection and storage of the generated biogas. Subsequently, when the biogas is extracted and utilized, the floating drum descends, repeating the cycle.

Methane Production and Storage Process

Methane generated in anaerobic digestion can be captured and stored efficiently in floating drum biogas plants, enabling sustainable energy production.

During the anaerobic digestion process, significant volumes of methane are generated as a byproduct. Methane, a potent greenhouse gas, can be captured and utilized as a renewable energy source. In the context of floating drum type biogas plants, the methane gas is stored within the floating drum until needed. Moreover, the inherent design of the floating drum enables the separation of biogas from the digested slurry, thus preventing any backflow of gas into the digestion chamber. This separation allows for the efficient and continuous production and storage of methane, contributing to the sustainable energy generation facilitated by these biogas systems.
