    Phytoremediation is an emerging technology nowadays due to demand in environmental sustainability which requires cost-effective solutions in terms of capital and operational cost. The treatment gain attention due to their potential in wastewater treatment especially in organics, nutrients, and heavy metal removal of domestics, agricultural, and industrial wastewater treatment. Plant functions in phytoremediation make the plant selection as an essential element. The plant should have the ability to tolerate with the toxic effluent and able to uptake the contaminant. Cyperus alternifolius (umbrella grass) was chosen as aquatic plant due to the ability to tolerance in municipal and industrial effluent sources with strong and dense root systems. Thus, the objectives of this study are to determine the potential and effectiveness of Cyperus alternifolius in the palm oil mill effluent treatment especially in the removal of organics (COD), nutrients (NH3-N and TP) and suspended solid. The batch experiment was run using Cyperus alternifolius to determine their potential of aerobic pond effluent for 21 days of treatment. Cyperus alternifolius treatment shows the great removal of COD and TSS with 96% and 91%, respectively at the end of 21 days of treatment. Nutrients removal achieved the maximum removal of 92% NH3-N and 99% TP shows after 11 days of treatment and percentage slowly decrease until the end of 21 days of treatment. Cyperus alternifolius had shown potential in the palm oil mill effluent treatment and can be combined with ponding treatment to enhance to water quality prior discharge.

    Livestock effluent is known to contain significantly higher concentrations of organic matter and challenging-to-degrade organic compounds compared to urban wastewater. This makes the effluent treatment challenging and adversely affects nearby aquatic environments if improperly treated. Phycoremediation uses microalgae in water and wastewater treatment. This research aim was to evaluate pollutant removal efficiencies, including chemical oxygen demand (COD), total suspended solids (TSS), nitrate (NO₃-N), turbidity, and phosphate (P), using microalgae Chlorella vulgaris (C. vulgaris) cultivation systems for livestock effluent treatment. The biomass weight of C. vulgaris in the cultivation systems was also observed. In this study, C. vulgaris was cultivated in closed cultivation systems in 5 L water bottles with different dilutions (100%, 75%, 50%, and 25%). The water effluent was compared to permissible values using the National Water Quality Standard (NWQS) class II for recreational water use. TSS was significantly removed by 61.97%, while COD and P were removed by 39.1% and 36.4%, respectively. The biomass growth was observed through the dry weight of the C.vulgaris. Therefore, the removal of nutrients from cattle farm effluent by phytoremediation using C. vulgaris demonstrates potential for treatment efficacy.
