Specialists from the environment protection service of the Novokuibyshevsk Petrochemical Company, a Rosneft subsidiary, are implementing a unique environmental project. For the first time, biological wastewater treatment has now been carried out at the enterprise’s facilities using Eichhornia water hyacinth plants.

Several Rosneft enterprises in the Samara Region use phytofiltration technology in their wastewater treatment plants. The Kuibyshev Refinery was a pioneer in its implementation, using not only water hyacinths but also pancratium and sweet flag to achieve a high degree of wastewater disinfection. Eichhornia seedlings have also been successful at the Syzran and Novokuibyshevsk refineries’ treatment facilities.

Eichhornia is more than just a beautiful ornamental plant. Its powerful root system acts as an extremely effective natural filter. The roots absorb bacteriological contaminants, suspended solids, phosphorus, nitrogen and other chemical compounds from the water, ensuring a high level of purification and improving the quality of the water to resemble that of natural waterways. Importantly, the plant is at its most effective during the warm season, when bacteria are most active and the risk of contamination is greatest.

During the flowering period, Eichhornia produces blue inflorescences that transform the water surface into a flower garden. Using plants in the wastewater treatment process is an example of implementing environmental solutions that are proven to be both economically and ecologically efficient.
