Root filtration by plants
Wetland plants (reeds, cattails) absorb nutrients from the water, and their roots aerate the substrate. The treatment takes place naturally, without chemicals.
The root system permeates the entire gravel bed, creating an extensive network that traps remaining impurities. Plants absorb nitrogen and phosphorus from the water and use them for their growth. At the same time, the root system aerates the bed, creating optimal conditions for both aerobic and anaerobic bacteria. The result is highly effective treatment in the constructed wetland without any chemicals. In the ECOver version, it operates gravitationally completely without electricity, while the ECOkocka version requires minimal electrical power for the blower.
