Effectiveness of vertical subsurface wetlands for iron and manganese removal from wastewater in drinking water treatment plants
Population growth and urbanization pose a greater pressure for the treatment of drinking water. Additionally, different treatment units, such as decanters and filters, accumulate high concentrations of iron (Fe) and manganese (Mn), which in many cases can be discharged into the environment withou...

Population growth and urbanization pose a greater pressure for the treatment of
drinking water. Additionally, different treatment units, such as decanters and filters,
accumulate high concentrations of iron (Fe) and manganese (Mn), which in many cases
can be discharged into the environment without any treatment when maintenance
is performed. Therefore, this paper evaluates the effectiveness of vertical subsurface
wetlands for Fe and Mn removal from wastewater in drinking water treatment plants,
taking a pilot scale wetland with an ascending gravel bed with two types of plants:
C. esculenta and P. australis in El Hormiguero (Cali, Colombia), as an example. The
pilot system had three upstream vertical wetlands, two of them planted and the third
one without a plant used as a control. The wetlands were arranged in parallel and each
formed by three gravel beds of different diameter. The results showed no significant
difference for the percentage of removal in the three wetlands for turbidity (98 %), Fe
(90 %), dissolved Fe (97 %) and Mn (98 %). The dissolved oxygen presented a significant
difference between the planted wetlands and the control. C. esculenta had the highest
concentration of Fe in the root with (103.5 ± 20.8) µg/g; while P. australis had the
highest average of Fe concentrations in leaves and stem with (45.7 ± 24) µg/g and
(41.4 ± 9.1) µg/g, respectively. It is concluded that subsurface wetlands can be an
interesting alternative for wastewater treatment in the maintenance of drinking water
treatment plants. However, more research is needed for the use of vegetation or some
technologies for the removal or reduction of the pollutant load in wetlands, since each
drinking water treatment plant will require a treatment system for wastewater, which
in turn requires a wastewater treatment system as well
