For the past decade, conventional filter media using River Sand (RS) has been commonly implemented as a stormwater management pollutant control to filter pollutants from runoff rainwater. However, the utilization of organic agro-based materials as biofilter media has yet to be fully explored and its potential in terms of physical properties to promote stormwater pollution filtration is still lacking in literatures. Therefore, this study discusses the potential of providing/shifting to a more organic and efficient filter media specifically Coconut Shell, focusing on filtration efficiency-influenced factors and its comparative filtration performances regarding Conductivity, Total Suspended Solid (TSS) and Turbidity percentage removal. The influence of operating parameters such as porosity and specific gravity of CS was analyzed through experimental method. This work evaluates the effectiveness of using CS as an agro-based filtration media. Additionally, the study also discusses a comparative analysis of three filter media design which are 100% RS, 100% CS and 50% CS + 50% RS filter column configurations to select the most optimum filter efficiency performance. Hence, the study demonstrated a successful application of CS as a potential sustainable adsorbent for the removal of stormwater pollutants (Conductivity, TSS and Turbidity) when operated at a condition of 50% CS + 50% RS filter media.
