Colmar: pollution of the Chulman river with coal dust is excluded
The coal mining company Kolmar has denied the information that has appeared on the Internet about the possible pollution of the Chulman River in Yakutia with coal dust. According to the company, advanced methods and technologies for minimizing the impact on the environment during coal processing are used in the construction and operation of the production facilities of the Denisovsky and Inaglinsky mining and processing complexes.
According to the press service of “Kolmar”, a closed water-slurry scheme with radial thickeners and chamber filter presses has been implemented at the Denisovskaya factory. This eliminates the discharge of process water into the environment.
Sludge pits are used in production, and wastewater treatment facilities with throughput up to 2 500 cubic meters per hour, which will be built in the future, should also minimize the environmental impact. They include four new additional sedimentation tanks, an aftertreatment station, as well as related engineering networks and communications.
