Wastewater treatment system

The Kele Effluent Wastewater Treatment System (KEWT) was developed by Ben Kele during the course of his Master's study at the Central Queensland University. The system is a recirculating on-site wastewater treatment and effluent reuse technology. The wastewater undergoes primary treatment and is then further treated through a lined sub-surface recirculating filter combined with an evapotranspiration area. The mixture of filter materials can be adapted to suit the treatment requirements; the most commonly used components are sand, blue metal, river rock, zeolite, scoria and charcoal.

The top of the filter is filled with a sandy loam soil suitable for the long-term application of effluent. A variety of native and exotic plant species are planted in the soil. The effluent flowing through the filters is absorbed by the soil and used by the plants. The plants provide additional treatment of the effluent through rhizofiltration and reuse the water through evapotranspiration.

Excess effluent can be recirculated through the system or diverted for other recycling purposes.
