Wetland system relies on renewable energy sources
such as solar and kinetic energy and wetland plants and micro-organisms, which
are the active agents in the treatment process. Wetlands can remove inorganic
nutrients, heavy metals, dissolved organic carbon, particulate organic matter,
and suspended solids from the water column and sediments, as well as play a key
role in supporting food webs and influencing global climate change through
their role in methanogenesis. Using constructed wetlands, wastewater can be
treated at lower costs than other treatment options, with low-technology
methods where no new or complex technological tools are needed. The system
relies on renewable energy sources such as solar and kinetic energy and wetland
plants and micro-organisms, which are the active agents in the treatment
process. There are inherent limitations to the effectiveness of constructed
wetland treatment system for wastewater treatment. Nevertheless, wetland
treatment is often the best choice for treatment or pre-treatment of wastewater
because of its low maintenance cost and simplicity of operation, high efficiency.
Moreover, wetland techniques enhance the aesthetic value of the local and
conserve the fauna and flora.
