Secondary clarifiers play a significant role in the successful operation of activated sludge systems. Because restriction available land, South Korean domestic wastewater treatment plants tend to employ rectangular settle mixed liquor suspended solids (MLSS) for A high MLSS concentration must be maintained bioreactor ensure nitrification during winters, and achieve stringent effluent quality. T...

The present study deals with the assessment of toxicity of distillery effluent on soil microorganisms and its quality improvement through bioremediation using Pseudomonas spp. Under lab scale experiment, different dilutions of distillery effluent i.e. 25%, 50%, 75% were used to examine effects on physico-chemical parameters of effluent and on soil microflora e.g. algae, bacteria, fungi and acti...

secondary clarifiers with large areas are widely applied in wastewater treatment plants. a pilot study was conducted to examine the possibility of applying one and two-stage inclined tube settlers instead of conventional secondary clarifiers. tube diameter in the first stage of the two-stage settler was wide as the conventional ones, but in the second stage, it was narrow to improve the efficie...

Secondary effluent reclamation and reuse is an effective solution to the water shortage problem, safety of reused a matter increasing concern. p-Nitrophenol (PNP), common secondary pollutant, can be efficiently removed using eco-friendly bioaugmented soil aquifer treatment (SAT) system at laboratory scale. In this study, sewage plant in Changchun was selected as case study apply SAT for field s...

Treated wastewater is increasingly being reused to achieve sustainable water management in arid regions. The objective of this study was to quantify the distribution of antibiotic resistance genes (ARGs) in recycled water, particularly after it has passed through the distribution system, and to consider point-of-use implications for soil irrigation. Three separate reclaimed wastewater distribut...
