EVRAZ NTMK’S ecologists plant green doctors
EVRAZ NTMK’s ecologists have planted green doctors in the draining pond of the Vyazovka River and Nizhny Tagil pond, including chlorella algae, water hyacinth roots and, for the first time, water lettuce plants.
The chlorella algae multiply rapidly in the pond water, absorbing carbon dioxide and saturating the water with oxygen, which oxidises organic and inorganic substances.
The root system of the water hyacinth, which closely resembles an orchid, cleans the water effectively. This year, the ecologists experimented with water lettuce plants, which originated in Africa. Unlike the water hyacinth, they take root at the bottom of the body of water, forming a barrier. Their roots also have an effective cleansing factor.
