Algae are sustainable sources of biomass for fuel, food, feed and essential for their growth are light, CO2, and inorganic nutrients like nitrogen and phosphorous. The aim of our study was to explore the effect of different carbon sources on biomass accumulation in microalgae Chlorella vulgaris and its ability to remove N and P compounds during its cultivation in aquaculture wastewater. Microal...

Membrane bioreactors are advanced treatment technologies that, compared to conventional processes, expected reduce antibiotic resistance spread in the environment due their superior biomass retention. In this study, metagenomic sequencing was used assess response of microbial community and profile an aerobic membrane bioreactor (AeMBR) anaerobic (AnMBR) operated parallel, treating identical syn...

This work presents a study about the elimination of anticancer drugs, a group of pollutants considered recalcitrant during conventional activated sludge wastewater treatment, using a biological treatment based on the fungus Trametes versicolor. A 10-L fluidized bed bioreactor inoculated with this fungus was set up in order to evaluate the removal of 10 selected anticancer drugs in real hospital...

Two different membrane treatment scenarios have been applied for of the high strength dark color alkaloid industry wastewater. A bioreactor (MBR) system having separately UF and MF membranes was operated with raw wastewater (scenario-A) anaerobically pre-treated (scenario-B). NF 270, 90 RO (XLE) were used as a polish-ing step at two recovery ratios 50% 75% both scenarios. In scenario-A, COD re-...

In this paper, the study of the dynamics and control of a semibatch wastewater neutralization process in modeling and simulation is presented. The wastewater neutralization process is modeled based on the reaction between a strong basic solution and a strong acidic solution in a semibatch reactor. It is assumed that the wastewater is acidic in nature. The semibatch system chosen here consists o...

Gas mixtures of H2S and NH3 are the focus of this study of research concerning gases generated from animal husbandry and treatments of anaerobic wastewater lagoons. A heterotrophic microflora (a mixture of Pseudomonas putida for H2S and Arthrobacter oxydans for NH3) was immobilized with Ca-alginate and packed into a fluidized bed reactor to simultaneously decompose H2S and NH3. This bioreactor ...

Membrane bioreactor (MBR) technology has previously been used by water industry to treat high salinity wastewater. In this study, an anoxic-oxic biofilm-membrane bioreactor (AOB-MBR) system has been developed to treat mustard tuber wastewater of 10% salinity (calculated as NaCl). To figure out the effects of operating conditions of the AOB-MBR on membrane fouling rate (KV), response surface met...
