Constructed wetlands ...
are an economic alternative to treat municipal waste waters locally.
Constructed wetlands are an eco-friendly, simple, and natural waste water treatment process with a long lifetime of more than 20 years.
Constructed wetlands are a biological waste water treatment in a reed bed sealed underneath with a plastic lining. Humus and minerals form a filter substrate which absorbs substances contained in the sewage and makes them available for biodegradation by micro-organism.With special minerals in the filter substrate also heavy metal ions can be absorbed. Constructed wetlands must have a preliminary sedimentation to separate the primary sludge in a multicompartment septic tank.
