Water Research, 1996 Abstract Three macrophytes are found to grow well in trenches filled with a secondary effluent of a wastewater treatment plant in the absence of any support medium: Canna, Cyperus and Paspalum. Daily concentration changes of nutrients in the wastewater as well as evapotranspiration of the macrophytes were studied batchwise.
