A new method of phytoplankton concentration as a cycle of solving environmental problems and obtaining energy from high-quality biofuel (lipid oil)

Abstract

The stagnant zones of fresh lakes, formed due to increased reproduction of phytoplankton in stagnant water under the influence of the sun, pose a serious threat to the environment, leading to the death of phytoplankton and fish, releasing hydrogen sulfide and making the water unsuitable even for agricultural use.
In this regard, the development of a method for concentrating phytoplankton from "green water" becomes an urgent task associated not only with the restoration of fresh water in lakes, but also with the effective use of the resulting concentrate to remove carbon dioxide, hydrogen sulfide and enrich the environment with oxygen.
On the other hand, the use of a high concentration of live, fast-proliferating phytoplankton cells with a lipid bilayer in the membrane makes it possible to obtain high-quality biofuel (lipid oil) in sufficient quantities.
Moreover, the process of obtaining biofuels is accompanied by a reduction in greenhouse gas emissions, which also has a positive effect on the environment.
The article presents just such a new developed method for phytoplankton concentration from "green water" not only for restoring fresh water in lakes, but also for the effective use of the resulting concentrate to remove carbon dioxide, hydrogen sulfide and enrich the environment with oxygen in a closed biological cycle, in which with the help of electrolytic hydrogen bubbles, formed during the electrolysis of an aqueous solution with phytoplankton cells, which have two unique properties: microdispersion and a negative charge of their surface, which allows them to form strong complexes in the act of flotation: the electrolytic hydrogen bubbles + phytoplankton cell, which float to the surface of the aqueous solution due to their increased volume in comparison with the individual components that ensures the successful completion of the flotation process - concentration and, as a result, part of the resulting concentrate is returned to lake to remove carbon dioxide and enrich of the environment with oxygen and as food for fish, and a significant part of the concentrate goes to the production of high-quality lipid oil.
The negatively charged catholyte solution, formed as a result of the ascent of negatively charged hydrogen bubbles, promotes the rapid reproduction of the emerging phytoplankton cells and, as a result, an increase in the amount of lipid oil.
