Abstract:

An experiment was conducted to determine feasibility of using several plant species in a pilot-scale nutrient film technique NFT installation to further treat primary-treated effluent. The reduction of biochemical oxygen demand, is discussed. Tracer studies showed that the hydraulic retention time of the wastewater in the NFT trays was inversely related to the wastewater application rate, and that for a given flow, plants with fine root systems such as reed canarygrass had a much longer detention time than plants with coarse tuberous rhizomes such as cattails. The BOD reduction could be described using the plug-flow reactor model with first-order kinetics. Author
