Results of Research on the Development of Structural and Technological Schemes for the Protection of Water Intake Technological Complexes from Blue-Green Algae

Abstract

AbstractThe article presents an overview of the cyanobacteria mass development (blue-green algae) in reservoirs, lakes and ponds that leads to a phenomenon called in literature - harmful water “blooming”. Experimental studies were conducted to create structural and technological schemes for protecting water intake technological complexes from blue-green algae. Experiment’s purpose was to visually determine the charge sign of cyanobacteria large colonies. During experiments, it was found that “living” cyanobacteria colonies have a negative charge sign, since they detected a characteristic movement towards the anode, and colonies of “dead” algae showed no characteristic movement towards the anode or cathode, which indicates the absence of a charge. Research on the structural and technological schemes’ development for protecting water intake technological complexes from blue-green algae was carried out in three stages: - trial coagulation in laboratory conditions; - filtering with the use of ruffe in the laboratory; - field research on the pilot plant. In conclusion, we propose a new technological and design method for improving the water ecosystem, in the water intake and treatment facility form in the bucket water intake conditions, which allows improving river ecosystems.KeywordsWater resourcesEcosystemBiocenosisIchthyofaunaFish stocksDrinking water qualityBlooming of reservoirs
