Bactogas - a product for biogas production increase

Bactogas is a bacterial powder product designed to stimulate, enhance and improve the efficiency of the anaerobic digestion process. The mineral carrier provides a place for the colonization of methanogens and acts as an ion exchanger to promote interspecies electron transfer. Bacillus strains were selected for their ability to increase the hydrolysis and fermentation phases, excluding anaerobes active hydrolytic enzymes.

• For anaerobic digestion biogas systems up to +45oC.
• Suitable for most production configurations and compatible with the vast majority of organic feedstock.
• A non-pathogenic, non-hazardous, environmentally safe and ready-to-use product to achieve the goal of the bio-economy

The combination of chemistry and biology promotes biogas production and reduces final sludge volume. The diverse metabolic capabilities of Bacillus allow the use of reactors in a wide range of configurations and organic substrates
The product is manufactured according to the ISO 9001 international standard
Stable spore formulas ensure long-term product stability

Areas of use:

• Sludge feeding systems
• Agricultural waste supply systems
• Slurry fed systems
• Food and municipal waste systems
• Landfill leachate systems
• Single-phase configurations
• Two-phase configurations
• Another complex configuration

The Bactogas mineral carrier acts to enhance the most sensitive microbial components of the anaerobic digestion process; methanogens and acetogens. Because Bacillus acts as a promoter of hydrolysis, which helps in the greater turnover and degradation of polymeric compounds such as proteins, carbohydrates and fats.
Due to this synergy, Bactogas can increase the amount of methane produced, reduce the final sludge volume, and improve the condition of the fermenter. The system is designed to increase stability and overall productivity, improve economic and environmental performance, and close the bio-economic cycle.

The combination of different bacterial species and strains gives Bactogas a bacterial mix that works over a wide range of pH values and temperatures, giving the operator a versatile tool for a variety of
for reactor types and configurations in various industries.
Bactogas strains help improve plant growth and properties, digestate and sludge value for agriculture.

HOW IT WORKS

The basis of biotechnology is a mineral combination of a carrier and selected Bacillus microorganisms. The new carrier acts in a multifaceted manner by enhancing the most sensitive parts of the anaerobic digestion process, mediated by acetogens and methanogens. The mineral surface pores allow deep-structured biofilm colonization and provide an additional layer of protection for these microbes. It makes them more resistant to environmental conditions such as pH fluctuations and the effects of inhibitory compounds such as ammonia

The mineral surface acts as an ion exchanger and facilitates interspecies electron transfer, greatly facilitating anaerobic respiration.
The surface of the mineral is also able to absorb compounds such as ammonia and hydrogen sulfide, reducing their inhibitory effect.

Bacteria consortia were selected for their diverse metabolic capacity and ability to function across a range of pH and temperature values. The ability of the bacillus to secrete hydrolytic enzymes in an anaerobic environment promotes the degradation of various polymeric compounds found in the substrate (proteins, polysaccharides and fats). This helps to liquefy the sludge (substrate) making it bioavailable for further degradation and for subsequent methane formation.
The ability to form resistant spores ensures that they will only begin to develop when conditions permit. This ensures long-term product stability and specificity.

Physicochemical element

• Methanogens colonize the inner pores of the mineral carrier
• Biofilm formation allows greater tolerance to environmental stress, the mineral surface facilitates interspecies electron transfer relocation. This promotes the activity and growth of methanogens

Biological component

• Bacteria secretes a range of hydrolytic enzymes to break down organic polymers into smaller more swellable particles
• The improved fermentation phase produces more hydrogen and acetate for methanogenesis

Both components enhance the most sensitive microbes, allowing a higher turnover of volatile fatty acids and higher methane generation. 

Bactogas use case:

Bactogas was dosed into sewage sludge for 3 months. The biogas plant receives 240m3 of sludge daily, of which 10% is consists of landfill leachate. pH 7, temperature +35oC, retention time 10 days. A boiler is used to heat the sludge (as fuel - diesel and biogas). Bactogas additive was dosed at 0.15% of the dry matter content. The initial dose is 50 kg, and then 10 kg daily.

Dosing was done using a modified tank for solution production and dosing to the sludge line.

Substrate supply: 10.3m3/h, digester volume 2500m3.

Result: dosing of the product reduced the sludge volume by 50% during the test period. and doubled the amount of gas. Costs for diesel, flocculant and sludge disposal were also significantly reduced. The economy reached 215,000 EUR.

The product is packed in bags of 20 kg.

ph limits 5-9, temperature up to +45oC
