ABSTRACT

The potential of using German grass (Echinochloa polystachya) in FTWs (Floating Treatment Wetlands) to treat municipal wastewater was investigated in this study. This mesocosm-based study was conducted over a 7-day Hydraulic Retention Period (HRT) with a total of 28 experimental days following a Randomized Complete Block Design (RCBD) with four treatments and three replicates. To evaluate system efficiency, mean temperature, PH, total dissolved solids (TDS), and electrical conductivity (EC) were also measured along with nitrate and phosphate concentrations. On day 28, the nitrate removal rate obtained with Pickerel weed was 88.65 % while German grass showed 86.56 % of remediation. On the other hand, while Pickerelweed removed 9.5 % of phosphate, German grass removed 7.47 %. The study demonstrated that the use of German grass in FTWs can be highly effective in the removal of nitrate ions from wastewater, while the removal of phosphate ions was minimal.
