Fermentation process additives
Biogas-Consult suggests solutions for optimizing the technological process - dosing additives inside bioreactors in the form of enzymes and micronutrients.
☑Enzymes Atres ZYmix plus 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.

☑ Trace elements Atres CX plus 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 trace elements:- 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%.
Micronutrients working principle
☑ Antifoam additives Atres Optimix plus – biochemical substances used in the technological process to prevent or reduce foam formation by substances prone to foaming.
Antifoam additives for the needs of biogas production consist of natural fats, fatty acids, alcohols and emulsifiers, absolutely free of mineral oils and silicones. They are biodegradable. This does not disrupt the biological process and does not lead to a toxic effect on the microflora of anaerobic fermentation.
Principle of action: antifoam agents form an insoluble impermeable film at the interface between the liquid and gas phases, thereby increasing surface tension and preventing the formation of gas bubbles, i.e. foam.
Dosage: 10 - 20 ml / m2 of substrate surface.
