Reedbed Systems

The Common Reed (Phragmites Australis ) can transfer atmospheric oxygen from its leaves, through its stem and rhizomes, and out via its root system (rhizosphere). Because of this, the rhizosphere is an excellent environment for micro-organisms, having zones of aerobic, anoxic, and anaerobic conditions.

Any waste water moving very slowly through the mass of Reed roots can be successfully treated, in a manner somewhat similar to conventional biological filter bed systems of sewage treatment.

It is essential that any form of treatment of sewage should have the capability to not only treat the sewage effectively, but also that its maturation time should be kept to a minimum. To achieve this, the reed plants are partially pre-grown.

Reed Bed Sewage Treatment Systems can be used to treat successfully a range of pollution concentrations, if designed and implemented correctly. There are a number of different design possibilities:

Vertical and Horizontal Reed Bed Systems (for a flat or sloping site)
Horizontal Bed System (for a flat or sloping site)
Sewage Treatment Works with a Tertiary Reed Bed (for a sloping site)
