Continuing the biological cleaning process for Taldicol, the small entity in question.
In the heart of Kazakhstan's capital, Astana, an ecological event aimed at restoring the water bodies of the Maly Taldyköl system has made significant strides. This project forms part of a long-term program dedicated to improving the condition of Astana's lakes and their ecological rehabilitation.
As of mid-2025, the biological purification project for the Maly Taldyköl system's water bodies is progressing with a focus on improving water quality and supporting ecological rehabilitation. The project employs natural purification methods, such as planting aquatic vegetation and utilizing bioaugmentation techniques to enhance microbial activity that breaks down pollutants.
The implementation phase has reported measurable improvements in water clarity and reductions in nutrient pollution, particularly nitrogen and phosphorus, common causes of eutrophication. Ongoing monitoring indicates gradual restoration of native aquatic flora and fauna, signaling a positive trend toward ecosystem balance. Local authorities and environmental groups continue to collaborate on expanding these biological purification methods across connected lakes within the system.
This project has had a profound impact on ecological rehabilitation. Increased biodiversity, as evidenced by the return of native species such as fish and aquatic invertebrates, is one of the notable outcomes. The biological approach also helps control excessive algae growth, which previously led to oxygen depletion, reducing harmful algal blooms. Improved water quality, with enhanced oxygen levels and decreased contaminants, is fostering healthier aquatic habitats, benefiting both wildlife and local communities relying on these water bodies.
However, full ecological rehabilitation is an ongoing process requiring continued efforts, regular monitoring, and adaptive management to address emerging challenges such as seasonal fluctuations and external pollution sources.
The event served to emphasize the commitment of the Astana community towards environmental safety and sustainable development. A coordinated effort involving employees of the scientific and analytical center, representatives of the akimat, volunteers, city residents, and media representatives participated in the ecological event. Cleaning was carried out on sections No5 and No7 of the water bodies, using modern domestic biological preparations.
These biological preparations, including liquid compositions based on Bacillus subtilis, B. amyloliquefaciens, B. pumilus strains, and EM-granules, help to decompose organic pollutants, suppress pathogenic microorganisms, restore microbial balance, and improve water and bottom sediment quality. Regular monitoring is being conducted to track changes, evaluate the effectiveness of applied technologies, and adjust further cleaning measures.
The project for biological purification of lakes is being implemented in stages, consisting of systematic introduction of preparations, sanitation of the shoreline, and constant ecological control. Aydar Rashid, the chief specialist of the Environmental Protection and Nature Management Department of Astana, highlighted the importance of collaboration between science, business, government, and society for environmental safety and sustainable development.
For those seeking detailed technical reports or the latest field data, they might be available through local environmental agencies or academic institutions involved in the project.
The biological purification project, employing techniques such as planting aquatic vegetation and using bioaugmentation methods, is expanding its efforts to enhance microbial activity and break down pollutants in other lakes within the Maly Taldyköl system (environmental-science). The project's success in improving water quality and restoring ecological balance in Astana's lakes has fostered healthier aquatic habitats for both wildlife and local communities, contributing to overall health-and-wellness and sustainable development (health-and-wellness, science).
