BOTANICAL TREATMENT SYSTEM

Wastewater is treated in an integrated system with anaerobic and aerobic solution. The aerobic solution is based on the botanical treatment system. The technique involves creating a bed of textured soil normally not more than 1 metre deep. This soil layer is planted with wetland plants. Wetland plants are so evolved to survive and grow in the inundated situation, because they have the capability to absorb atmospheric oxygen through the stomatal openings and push it through the aerenchyma to the rhizosphere.

The photosynthetic activity of the plants creates an aerobic region near their roots. The wastewater is made to Row through this soil layer vertically or horizontally by distributing the untreated wastewater using materials available locally. This results in aerobic treatment of water involving very low maintenance costs.
