The removal of organic pollutant in wastewater has become a major priority water treatment. In this study, dibutyl phthalate (DBP) been biologically and photocatalytically degraded using modified transition metal dichalcogenides. as-synthesized nanoparticles were characterized various characterization techniques, which includes XRD, Raman, FT-IR, SEM, TEM, UV-Vis, XPS, PL, EIS, photocurrent res...

In this study, the enhanced photodegradation of a high-concentration phenol red (PR) using very fine TiO2 nanocrystals by adding KBrO3 electron acceptor was reported for first time. The structural study on HRTEM, XRD, Raman, and EDX performed it confirmed anatase phase nanocrystals. UV–Vis absorbance 20 mg.L?1 PR measured extracted. concentration effects exhibited an important enhancement in de...

Biohazards are widely present in wastewater, and contaminated water can arouse various waterborne diseases. Therefore, effectively removing biohazards from water is a worldwide need. In this study, a novel visible-light-driven (VLD) graphitic carbon nitride (g-C3N4)/TiO2 hybrid photocatalyst with high photocatalytic bacterial inactivation activity was successfully synthesized using a facile hyd...

normal 0 false false false en-us x-none fa background: nowadays wastewater is one of the important sources of environmental pollutions and   one of the aims of wastewater treatment is to maintain a healthy environment. nonstandard wastewater discharges and their use in agriculture or discharge to surface water will follow environmental and health hazards. the aim of this study was to compare th...

background: wastewater produced by a dairy in sanandaj is a major source of environmental pollution threatening the city. the dairy uses activated sludge treatment to remove organic pollution from the wastewater. the present study evaluated the performance of this process and its compliance with national requirements for chemical oxygen demand (cod), biochemical oxygen demand (bod), and total s...

a membrane bioreactor (mbr) system based on a dead-end immersed hollow fiber membrane and filamentous fungus aspergillus oryzae were used for treatment of baker’s yeast wastewater. the fungus was adapted to the wastewater in the bioreactor for two weeks before starting the continuous process. average organic loading rate of 4.2 kg cod/m3.d was entered the bioreactor. mbr system was able to redu...

Trials on ciprofloxacin removal from real aqueous systems were performed using a photocatalytic membrane reactor with catalyst in suspension. Four sets of four treatment cycles carried out and experimental results processed the statistical point view order to assess reproducibility. Global efficiencies more than 99.85% obtained for all cycles. Coupling degradation process allowed separation reu...
