Abstract

Evaluation of hydraulic conductivity in a phragmites wastewater treatment plant M. Mastrorilli, E. Ranieri, V. Simeone Dipartimento di Ingegneria Civile ed Ambientale Facolta di Ingegneria di Taranto. Politecnico di Bari, Italy Abstract This paper reports first result of absorption tests for the evaluation of the permeability of two constructed wetland plants built up near Putignano (B A) for the treatment of local wastewater municipal treatment plant effluent. These fields were planted with phragmites australis hydrophytes and covers an area of approx. 2,000 nf. They have been designed with Kickuth Root-Zone Method [1]. The assessment of the operational parameters of the system - hydraulic conductivity (permeability) in particular is very useful to obtain good design criteria - is quite difficult for the presence of coarse grained gravels mixed with rhizomes, for the influence of evapotranspiration and because of the different conditions of phragmites during the year.
