The second stage of the reconstruction of biological treatment facilities began in April at JSC "Nizhnekamskneftekhim" (Nizhnekamsk).

The facilities take for treatment not only chemically contaminated effluents of the industrial unit, but also domestic sewage of the whole city.

The first stage of reconstruction, conducted in 2015-2016, was estimated at 600 million rubles (~8.5 mln euro) and provided for the modernization of the cleaning unit of domestic sewage.
Within the framework of the second, a modernization of the mechanical treatment unit for chemically contaminated sewage is planned. As a result, industrial effluent will be fed to the pre-aerators after preliminary treatment and then to the biofilters.
The cost of the second phase, which is planned to be completed by the end of 2018, will be about 1 billion rubles (~14 mln. euro).
