Reed beds have comparatively low operating costs when compared with established biological treatment systems. As flow by the system is regulated by gravitation, there are no prerequisites for pumping as soon as the wastewater is in the reed bed. Likewise, as a natural process is helped by the reeds, there is no requirement for blowers to ventilate the system. Per se, there are no automatic or electrical necessities.
Reed beds have a high level of physical, chemical, and biological density. The management of wastewater is attained by a combining of the microorganisms and the corporal and chemical attributes of the solid media and the reeds, inside the reed bed. Furthermore, wastes are caught and altered by physical and chemical paths.
Due to the low level of technical features for reed beds, there is no prerequisite for well-trained operators. As the degradation of the effluent takes place inside a solid matrix, it should free from odor. Reed beds provide high flexibility for both the density and content of wastewaters as these schemes have a high variety of microorganisms. Reed beds may acclimatize to different kinds and unstable shock masses of effluents, including complicated waste waters comprising organic compounds like disinfected hydrocarbons, dyestuffs and sulphur comprising aromatics, and hard metals and pathogens.
