Specialists from the environmental protection service of the Novokuibyshevsk Petrochemical Company (part of Rosneft) are implementing a unique environmental project. For the first time, the company's wastewater treatment facilities will use water hyacinths (eichornia) to bio-purify wastewater.
The phytofiltration technology at the wastewater post-treatment unit is used by several Rosneft enterprises in the Samara region. The pioneer of implementation was the Kuibyshev Oil Refinery, where not only water hyacinths, but also pancratium and calamus help to achieve a high degree of wastewater disinfection. Eichhornia seedlings have proven themselves well at the treatment facilities of the Syzran and Novokuibyshevsk Oil Refineries.
Eichhornia is not just a beautiful ornamental plant. Its powerful root system works as a highly effective natural filter. The roots absorb any bacteriological contaminants, suspended matter, phosphorus, nitrogen and other chemical compounds from the water, providing a high degree of disinfection and bringing the quality of purified water closer to natural reservoirs. It is important that the plant is effective precisely in the warm period of the year, when bacteria are most active and the risk of contamination increases.
During the flowering period, the Eichhornia produces blue inflorescences, turning the water surface into a flower garden. The use of plants in the process of additional wastewater treatment is an example of the implementation of environmental solutions with proven economic and environmental efficiency.
