Application of Salvinia molesta for water pollution treatment using phytoremediation batch system

The contamination of the river water with wastewater is a severe problem due to the utilization of the river water for drinking water mainly. Phytotechnologies can minimize the negative impact of this problem using plants in the river water rehabilitation. This study aimed to evaluate the potential of Salvinia molesta to phytoremediation of the polluted river by organic pollutants. There were two treatments on this research: polluted river without Salvinia molesta and polluted river with Salvinia molesta phytoremediation on the batch system. We took a water sample from the moderate polluted river for phytoremediation by Salvinia molesta. The period of the research was two weeks. The measured water quality parameters in this study were dissolved oxygen (DO), total solids (TS), total dissolved solids (TDS), biological oxygen demand (BOD) and chemical oxygen demand (COD). This study revealed that Salvinia molesta plants could improve the river water quality with enhancing DO by 58,26%, decreasing the parameters include TS by 31%, TDS by 97%, BOD by 26%, and COD by 74% compared to control without Salvinia molesta. Thus, the data suggest that Salvinia molesta may have a potential for phytoremediation (as water pollution treatment) of aquatic environments contaminated with organic pollutants from wastewater.
