Abstract
Wastewater contamination is one of the most common environmental issues which pose serious ecological problems, threaten biological safety, and cause great economic losses. Several methods have been used for the wastewater. However, the application of phytoremediation treatment is a promising and environmentally friendly method to avoid the secondary contaminations pose by the treatment dosage in other methods. The current work aimed to assess the phytoremediation treatment of the pre-treated domestic wastewater using the Salvinia molesta and Water hyacinth plants. Moreover, water quality tests were performed in the current research to display the effects of the phytoremediation treatment using Salvinia molesta and Water hyacinth plants on the responses of water quality parameters. The removal results were analysed using response surface methodology (RSM) based on pH level and hydraulic retention time, HRT, while the removal rate was determined based on the reduction in the chemical oxygen demand (COD), total dissolved solids (TDS), total nitrogen (TN) and turbidity. The optimal removal of COD, TDS, TN and turbidity in the current study was 56.47, 83.00, 52.12, and 79.98 % respectively for the Salvinia molesta and 48.81, 24.00, 13.56 and 19.89 % for the Water hyacinth.
