| Abstract | Wastewater is an effective alternative to water reuse. Reusing treated wastewater from domestic wastewater treatment plants can help address the issue of water shortage in the future and improve reuse potential in various activities e.g., agricultural, domestic, industrial, environmental, and recreation. Currently, most of the wastewater treatment plants (WWTP) in Bangkok Metropolitan Administration (BMA) were designed for secondary treatment with limited reuse of their treated effluent. Additionally, pathogenic indicators which are fecal coliforms from effluent quality do not meet the reuse standard. In this context, improper discharge of treated wastewater could result in several environmental concerns. To improve the quality of effluent, especially fecal coliform and other pollutant removal, the filtration system is considered to solve this problem. This study aims to determine the reuse potential and improve the quality of the secondary effluent treatment by developing an adsorptive media from waste residue and other additive materials. The developed adsorptive media (with the combination of the waste residues and other additive materials e.g., coconut shells, waste tea leaves, bentonite, zeolite, magnesium oxide, dolomite, marl, and slaked lime) could use as a tertiary treatment of wastewater treatment system, which could help promote a path through and remove the pollutants in the wastewater passes filtration processes. The developed adsorptive media from the combination of coconut shells or waste tea leaves, magnesium oxide, bentonite, and zeolite, could significantly inactivate fecal coliforms present in wastewater for 5.21 Log10 reduction employed by filtration columns under HRT 6 hours. Additionally, it also could remove phosphorus (P), nitrogen (N), total suspended solids (TSS), turbidity, and chemical oxygen demand (COD) as well as improve dissolved oxygen (DO) quality and could help to enhance the quality of effluents for meeting the wastewater reuse standards and guidelines. |
