Biological-based Response Evaluation of Different Reclamation System using Combination of Conventional Bioassay and Gene Expression Analysis as Test Battery

Research abstract

Reclaimed water has recently become a popular as a re-use source for water supply for various applications. However, despite the advancement in reclamation processes, it is not guaranteed to completely remove the presence of micropollutants in the water. In addition, chemical analyses are not quite enough to have a comprehensive assessment of whole effluent quality. The aim of this study is to evaluate the toxicity of different reclamation systems through the use of bioanalytical tools. Four effluents secondary treated effluents were used: air-sparged side-stream membrane bioreactor I & II (AS-MBR I & II), submerged MBR (S-MBR), and activated sludge (AS). Secondary treated effluents were also further treated with tertiary/advance system nanofiltration (NF), reverse osmosis (RO), rapid sand filtration (RSF), chlorination (Cl) and ozonation (Oz).
