EXTRACTION CAPACITY OF GRASSES GROWN IN CONSTRUCTED WETLAND SYSTEMS USING DIFFERENT ARRANGEMENTS AND SUBSTRATES

ABSTRACT Constructed wetland systems have been used to treat different wastewater; among their essential components are the cultivated plant species and type of substrate used to fill them. The choice of plant species and type of substrate are important for the good system performance in wastewater treatment. This study aimed to evaluate the extraction capacity of Napier and Tifton 85 grasses when cultivated at different positions in horizontal subsurface flow constructed wetlands (HSSF-CWs) filled with different substrates in wastewater treatment from a bulk milk-cooling tank (MTWW). The expe...
