Yes Maximum ROI is not achieved by the cheapest plant.

It is achieved by the lowest cost per cubic meter of methane produced.

YES<br data-start=”416″ data-end=”419″> Different digesters host different populations of hydrolytic bacteria, acidogens, acetogens, and methanogens. The dominance of specific methanogens (acetoclastic vs. hydrogenotrophic) influences the methane-to-CO₂ ratio in the biogas. The type of organic waste (food waste, manure, crop residues, industrial…

Hi How to produce cheaper biogas? Means maximum ROI which means less CAPAX and OPEX. Or

We can say the cost of biogas mainly depends on how much methane we extract from the same feedstock and infrastructure. Our team improves the Plants ROI by improving the conversion efficiency of organic waste into methane, which reduces the…

Anaerobic digester efficiency depends mainly on how much of the feedstock’s theoretical methane potential (BMP) can actually be converted into methane, which in practice is usually 70–85% for well-designed plants . The largest efficiency losses occur during hydrolysis of complex biomass (especially lignocellulosic materials like straw),…

Measuring Total VFAs (Volatile Fatty Acids) in a biogas plant can be done by several methods. The two-point titration method (Nordmann ) is widely used in biogas plants because it is fast, inexpensive, and suitable for daily plant monitoring. However, it is not the most accurate scientific method for total VFA quantification.

Total VFA concentration above 2,000–4,000 mg/L (as acetic acid) or a VFA/Alkalinity ratio (FOS/TAC) above 0.3–0.4. More then 0.4 ratio indicates High risk of acidification/failure; immediate reduction in organic loading rate (OLR) is required. Long-Chain Fatty Acids (LCFAs) are particularly dangerous as they can cause sludge flotation…

Biogas plant failure in India is rarely due to wrong technology selection alone but more because of budget constraint leading to compromised plant design. The real issue is inadequate systems engineering. A successful biogas project requires the integration of feedstock logistics, pretreatment, digester design, microbial process control,…

Fortnightly is a good start to do VFA Profiling. For stable digesters fortnightly may work, but during process disturbances or optimization, weekly or even daily monitoring is recommended.

High propionate concentration occurs due to thermodynamic challenge because of high concentration of hydrogen in the reactor. This indicates…

ADM1 Model can also help us to understand microbial dynamics in two stage Anaerobic digestion process which release a lot of feedback inhibition because of product buildup. We tried working with daily effluents treatment by using anaerobic reactors.
