Abilities of stratified filter and wetland to reduce TDS and TSS in blackwater domestic waste

摘要

This study aimed to devisea new design of domestic waste treatment which can produce an output of class IV water(irrigation water)based on measurement of TDS(Total Dissolved Solid)and TSS(Total Suspended Solid)parameters.The physical model tested in this research wasa stratified filter consisting of compositionsfrom coarse to fine materialsnamely gravel,charcoal and sand.Furthermore,filtering blackwater waste was refined by remediation with Cattail(Typha Angustifolia)and Vetiver {Vetiveria Zizanoides).The physical model of WWTP was set to 1:25 added by a stratified filter in the upstream section.Observations were done by measuring blackwater TDS levels prior to treatment,after going through a stratified filter,and after going through a remediation process with aquatic plants.The results showed that stratified filters and wetland can reduce TDS levels in blackwater until it reached the standard for irrigation water.
