Different pre-treatment processes were applied to investigate the removal of chemical oxygen demand (COD) from paper mill effluent. The objective of this paper is to find the optimal operating conditions for coagulation process. The effect of key operational parameters, including the type of coagulant, initial pH, temperature, and coagulant dose, on the percent removal of… Continue reading Cost-effective removal of cod in the pre-treatment of wastewater from paper industry
Global consideration has been growing recently to tackle the toxic and carcinogenic effects of heavy metal presence in water streams. In this work, novel polyvinylidene fluoride (PVDF)/tin(IV) oxide (SnO2) ion exchange membranes were prepared via the phase inversion method and their performance and properties were analyzed. The results showed that the addition of SnO2 nanoparticles… Continue reading Preparation of novel polyvinylidene fluoride (PVDF)-Tin(IV) oxide (SnO2) ion exchange mixed matrix membranes for the removal of heavy metals from aqueous solutions
This study aimed at understanding how bacterial communities fluctuate and correlate with wastewater treatment plant (WWTP) efficiency over a ten-month period. Illumina sequencing of 16 s rRNA gene variable regions was performed on genomic DNA extracted from aeration tank samples collected twice a week and analyzed using the Bioinformatics Tool Quantitative Insights into Microbial Ecology… Continue reading Correlation between bacterial community structure and performance efficiency of a full-scale wastewater treatment plant
Pharmaceutical active compounds (PhACs) have been detected at significant concentrations in various natural and artificial aquatic environments. In this study, electro membrane bioreactor (eMBR) technology was used to treat simulated municipal wastewater containing widely-used pharmaceuticals namely amoxicillin (AMX), diclofenac (DCF) and carbamazepine (CBZ). The effects of varying current density on the removal of PhACs (AMX,… Continue reading Are pharmaceuticals removal and membrane fouling in electromembrane bioreactor affected by current density?
The present study investigated the influence of electric field on the removal of quorum sensing (QS) and emerging contaminants using an electrochemical membrane bioreactor (eMBR). A significant reduction of N-octanoyl-L-homoserine lactone signal molecules (∼76%) was achieved in the eMBR, with respect to the level observed in the conventional MBR as the control. Furthermore, the intermittent… Continue reading Control of quorum sensing signals and emerging contaminants in electrochemical membrane bioreactors
