Chemtech Biogas Plus Additive

Chemtech Biogas Plus Additive is a powder product designed to stimulate, bolster and improve the efficiency of the anaerobic digestion process.

The mineral carrier provides a site for colonisation of methanogens and acts as an ion exchanger to boost the interspecies electron transfer. The Bacillus strains have been selected for their ability to boost the hydrolysis and fermentation phases by the secretion of anaerobic active hydrolytic enzymes.

The synergy between the chemistry and biology act to boost biogas production and reduce final sludge volume. The diverse metabolic capability of the Bacillus allow use in a wide range of reactor configurations and organic substrates.

Chemtech Biogas Plus Additive is manufactured in accordance with recognised international standard ISO 9001 to guarantee quality, integrity and reproducibility. Stable spore formulations offer long term product stability.

How It Works

The biotechnology platform is a combination between a novel mineral carrier and selected Bacillus microorganisms. The novel carrier acts in a multi facetted manner to bolster the most sensitive portion of the anaerobic digestion process, which is that mediated by acetogens and methanogens.

The pores within the mineral surface allow for deep structure biofilm colonisation which confers an extra layer of protection to these microbes. This makes them more tolerant to environmental conditions such as swings of pH and exposure to inhibitory compounds like ammonia.

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

The Bacillus consortia have been chosen due to their diverse metabolic capability and ability to operate across a range of pH and temperature values. The capacity of the Bacillus to secrete hydrolytic enzymes under anaerobic conditions boost the degradation of a range of polymeric compounds found in sludge such as protein, polysaccharides and fats. This helps to liquefy sludge making substrates bioavailable for further degradation and subsequent methane generation.

The ability to form resistant spores ensures that they will only germinate when the right conditions allow them to, offering long term product stability and specificity.

The Technology

Chemtech Biogas Plus Additive is a biotechnological solution towards improving the anaerobic digestion system. It is a granulated powder that is dosed directly into the system. It combines a novel mineral carrier with Bacillus bioaugmentation to provide a physiochemical and biological response.

This synergy between chemistry and biology delivers significant improvements above and beyond using these technologies in isolation. The carrier acts to bolster the most sensitive microbial components of the anaerobic digestion process; the methanogens and acetogens. Whereas the Bacillus acts to provide a hydrolytic boost to assist in the greater degradation and turnover of polymeric compounds such as proteins, carbohydrates and fats.

Through this synergy, Chemtech Biogas Plus Additive can increase the amount of methane produced, decrease the final sludge volume and help to bolster the system it is dosed into enhancing stability and overall productivity, providing both economic and environmental improvements that contribute towards the closing of the bio-economic loop.

The combination of different Bacillus species and strains gives Chemtech Biogas Plus Additive a diverse mix of microbes that can operate over a wide range of pH values and temperatures, providing the operator with a versatile tool for the diverse range of reactor configurations and feed types present across different industries.

The strains within Chemtech Biogas Plus Additive are also known for their plant growth promoting properties and have the potential to improve the value of digestate and sludges destined for agricultural uses.

The Chemtech Approach

Why Is Chemtech Different?

At Chemtech we ferment all our own bacteria to the highest standards (ISO 9001) so we can guarantee that the Bacillus we deliver are correct in both species and concentration and are free from contaminants. We have taken time to design our products to ensure they have minimal impact upon the environment and end user, whilst at the same time offering an efficacious and prolonged impact.

As bacilli comprise the core of our technology, we ensure that we understand each of our isolates. We have invested in cutting edge genomic techniques to fully comprehend the potential of each of our bacillus species, and in doing so we have created effective and truly application-specific technology.

All of our products come with expert technical support as standard.

Case Study

Overview: A single stage WWT sludge fed system was dosed with Chemtech Biogas Plus Additive over a 3 month period. The plant receives 240m3 of WWT sludge per day with 10% of that volume coming from the chemicalphysical of landfill leachate. It operates at pH 7 and 35°C with a residence time of 10.4 days. A boiler is used to heat the sludge which is powered by both diesel and biogas. The sludge is disposed of via landfill after thickening using a flocculent and belt press.

Solution: Chemtech Biogas Plus Additive was dosed at 0.15% of the dry matter inlet concentration, with an initial slug dose of 50kg followed by a daily dosage of 10kg. Dosing was performed on site using a modified tank to create a slurry with influent and pump it into the system before the heat exchanger.

Results: Dosing of Chemtech Biogas Plus Additive was able to significantly reduce sludge volume by half and double biogas production consistently during the trial period. This resulted in significant cost savings from less boiler diesel usage, lower flocculant use and lower sludge disposal costs. The overall cost saving over the trial period totalled over $200,000.
