This learn, performed in Kenya, provides the 1st perception into the functionality of a built therapy wetland receiving pulp and paper mill wastewater within the tropics.

The wetland successfully got rid of natural topic, suspended solids, phenols and meals. BOD and phenols relief premiums are suggested for the 1st time. layout parameters and instructions for the set-up and upkeep of a full-scale wetland are instructed. The learn concludes that integrating a full-scale wetland, as a tertiary level with the prevailing therapy ponds may considerably enhance the standard of water in River Nzoia downstream of the effluent discharge.

This is a useful source publication for scientists, managers and scholars within the box of wetland ecology, water and environmental management.
