Biotechnology of extraction of methane and fertilization from hydrobionts PP028
Purpose and scope.
The development is intended for the production of biogas from the organic mass of hydrobionts. In particular from blue - green algae (Cyanobacteria).
For the purpose reduction of surface water contaminationas as for the use of dazzstat as mineral organics fertilizer.
Key features, the essence of the development.
Ecological bioenergy technology is developed, which provides cost - effective production of methane and biomass fertilizers from blue - green algae harvested during "flowering" water reservoirs of the Dnipro cascade.
The technical result is obtaining in the mesophilic (30 С) anaerobic conditions of 3, 4 4 dm3 biogas from 1, 0dm3 of a concentrated substrate (p=1)for 37 days and 4, 38 dm3 for 42 days –from cavitated substrate. Defined it Quantitative and qualitative composition: CH 4 + H 2 (71. 3% ), СО2 (20, 4% ), N 2 (6, 5% ) and other gases (1, 9% ), and heat combustion: Q = 5. 2 MJ / m3. Chemically determined composition and degree of dilution of biofertilizers for 12 cultivated plants that provides increase in yield by 7. 5 - 12%

Five Ukrainian patents were obtained
Main benefits of the development
The development differs by the type of used substrate and quantitative composition of biogas.
Magnification the content of methane is achieved at the expense of almost complete the disappearance of the hydrogen sulfide. Hydrogen sulfide is part of the composition biogas. It’s obtained from other substrates, and causes corrosion of metal structures. Withdrawal Cyanobacteria with water minimizes ecological threat caused by the consequences of "flowering" of water. Also improves the quality of drinking water in the region.
The main customers of the development are municipal structures, farms, agrarian and forest enterprises etc.
The state of readiness of development
Design documentation is created on the manufacture of component parts stationary complex from a concentration column.
An anaerobic chamber providing production loop controlled by the original software the product.
Bioassay was conducted mineral organic fertilizer and its approbation in the cameral and field conditions. Composed technical specifications for products.
