Fermentation process additives

Biogas-Consult suggests solutions for optimizing the technological process - dosing additives inside bioreactors in the form of enzymes and micronutrients.
☑Enzymes are highly specialized proteins that are classified by the type of reaction which they catalyze. We suggest a product that is capable of providing very fast destruction of organic matter, decomposing it to the smallest constituents - monomers.
Appointment of enzymes:- Decomposition of the cortical layers of the substrate from top;- High viscosity, mixing problems;- High content of cellulosic material (silage, grass, straw);- High starch, corn grains;- High content of sugar beets (whole beets, as well as pulp of sugar beets as a by-product);- High in fat and protein (organic waste);- Acceleration of biogas production by 5-18%.
Dosing: 0.5 - 2.0 L per 1 MW of installed biogas plant capacity per day (depending on the type of feedstock and its concentration, as well as on the basis of analysis of fiber and carbohydrate-lignin composition of feedstock).
Expected Result:- The destruction and degradation of the cortical layers of biomass;- Decrease in viscosity, reduction of energy consumption for mixing;- Increased degradation, low level of load on organic matter;- Low potential residual gas;- Stabilization of anaerobic fermentation.

☑ Micronutrients are microelements additives obtained by the reaction of the corresponding microelements with a chelated organic acid. The use of micronutrients is aimed at stabilizing and optimizing the microflora of anaerobic fermentation.
Appointment of micronutrients:- Violations of biological processes → high FOS, low pH, low CH4 content;- Process instability → various biogas production and unstable percentage of CH4;- High organic load on the bioreactor;- Unstable loading of raw materials → violation of biological cyclicity;- Different requirements for the hydraulic residence time for each of the used components of the raw materials, and its different biopolymer composition;- Too quickly degradable raw materials → to prevent quick acidification;- High propionic acid content.
The use of micronutrients is especially important for highly loaded bioreactors, as well as bioreactors operating on monosubstrate!
Dosing: 0.2 - 1.0 L per 1 MW of installed biogas plant capacity per day (depending on the type of feedstock and its concentration, as well as on the basis of analysis of atomic absorption spectroscopy).
Expected Result:- Decrease FOS value, less than 1000 mg/l;- Increase in the proportion of CH4 in biogas;- Stabilization of biogas production;- Elimination of violations of the biological process;- The ability to use a larger volume of biomass and, accordingly, access to higher production capacities;- Reducing the organic load on the bioreactor;- Stabilisation of C:N ratio;- Increase in buffer capacity, respectively, lowering the ratio of FOS/TAC;- An increase in biogas production by 3-8%.
