Utilisation of an aquatic plant (Scirpus grossus) for phytoremediation of real sago mill effluent

Phytoremediation technology is one of the most promising treatment methods for wastewater, especially from food and agricultural effluent.

Description
Summary:Phytoremediation technology is one of the most promising treatment methods for wastewater, especially from food and agricultural effluent. In this experiment, sago mill effluent (SME) was treated through phytoremediation. The present study aimed to explore the potential of a native aquatic plant, Scirpus grossus, to reduce the concentrations of total suspended solids (TSS), chemical oxygen demand (COD), and biological oxygen demand (BOD) in SME before installing a full-scale system, to ensure the effectiveness of the remedy. Two systems, subsurface batch (SS) and free-surface batch (FS), were applied to select a better system to treat SME using S. grossus. After 80 days of experimentation, the findings indicate that the plant can better survive in the SS batch system compared to the FS batch system. Furthermore, the plant can reduce TSS, COD, and BOD by 98, 88, and 93%, respectively. Therefore, it can be concluded that S. grossus has remarkable potential in the removal of pollutants in the phytoremediation of SME. [Display omitted] •Novel study of phytoremediation for sago mill effluent (SME) was first reported here.•Native aquatic plant species i.e. Scirpus grossus was used to facilitate the treatment of SME.•The planted aquariums superseded the unplanted ones in all removals of TSS, COD and BOD.•Batch subsurface (SS) surface performed better compared to free surface (FS) system.•The highest removals in SS system were 98%, 88% and 93% for TSS, COD, and BOD, respectively.
