What are the biological processes used in wetland systems?
The basic biological treatment processes used in the system include waste stabilization ponds and constructed wetland systems, trickling (or percolating) filter systems, and activated sludge systems. An aerobic stabilization pond is a large and shallow excavation in the ground, where the treatment of the waste occurs by natural processes involving the use of both bacteria and algae. In aerobic ponds, oxygen is supplied by natural surface re-aeration and by algal photosynthesis. Higher animals such as rotifers and protozoa are also present in the pond. Their main function is to predate on the bacteria, and to a lesser extent on algae, which helps in controlling the suspended solids (SS) concentration in the effluent. Ponds in which the stabilization of wastes is brought about by a combination of aerobic, anaerobic, and facultative bacteria are known as facultative stabilization ponds. The three zones in such ponds include a surface zone where aerobic bacteria and algae exist in a symbiotic relationship, an intermediate zone that is partly aerobic and partly anaerobic in which the decomposition of organic matter is carried out by facultative bacteria, and an anaerobic bottom zone in which accumulated solids are decomposed by anaerobic bacteria.
How is oxidation accomplished?
Oxidation is accomplished by adding chlorine to the pretreated wastes in an aeration basin. Oxygen from air and chlorine are the oxidizing agents. Spent activated carbon can then be recovered (partially) by the process of heating (incinerating). View chapter Purchase book.
