Soil based reed beds are a versatile technology with applications in many different industries.

The superior microbial activity of a soil based reed bed means it can be used to treat a wide range of different contaminants across many different industries. Most organic contaminants can be degraded within a soil based reed bed, even complex chemicals and persistent organic pollutants (POPs). Inorganics cannot be degraded in the same way, but an adapted soil reed bed can be used to entrap metal pollutants and phosphates and remove them from the water.
