Development of biotechnologies for cleaning of water bodies on the Absheron Peninsula from organic and inorganic pollutants

This article addresses the issues of lake pollution in the area of the Absheron Peninsula and introduces new approaches to enhancing their self-purification capacity. For the purification of organic and inorganic contaminants of lakes on the Absheron Peninsula, the prospects for using activated sludge microorganisms and the Fermi Start preparation, consisting of an association of microorganisms, were studied. The research found that the use of activated sludge microorganisms can reduce the amount of phenol in the waters of Lake Boyukshor by 99%. Furthermore, it was determined that the Fermi Start preparation is more effective in purifying water contaminated with heavy metals. For example, during one hour of experimentation, the degree of copper removal reached 78%, reducing the metal concentration in water to near the maximum allowable concentration (MAC) of 1.0 mg/L.
