The increasing use of antibiotics by humans and their persistence in the environment leads to development drug resistance, which is nowadays considered as an environmental problem. aim this study was determine efficacy sono-electro-Fenton process for removal Cefixime antibiotic from aqueous solutions Response Surface Methodology (RSM) evaluate toxicity effluent microorganisms. In present study, degradation synthetic wastewater containing investigated a reactor (with useful volume 1 L)...

Abstract This study was performed to determine the efficiency of electro/persulfate process remove basic violet 16 (BV16) dye and COD from aqueous solutions. The present experimentally on a laboratory scale. effect pH investigated independently, after performing experiments, voltage (volts), dose persulfate (g/L), initial concentration BV16 dye, electrolysis time with model presented by Box Behnken design, optimal conditions for removal obtained. Under conditions, toxicity changes during...

Abstract Beta-lactamase-producing Enterobacterales bacteria cause severe hard-to-treat infections. Currently, they are spreading beyond hospitals and becoming a serious global health concern. This study investigated the prevalence molecular characterization of extended-spectrum β-lactamase AmpC-type β-lactamase-producing (ESBL-PE, AmpC-PE) in wastewater from livestock poultry slaughterhouses Ardabil, Iran. A total 80 belonging to 9 species were identified. Among isolates, Escherichia coli (n...

The aim of this study was to determine the toxicity cefixime in inlet solution and effluent treated with sono-electro-Fenton process using standard strains microorganisms. This research performed as an experimental study, which conducted on a laboratory scale. Escherichia coli (gram-negative) Staphylococcus aureus (gram-positive) were used for bioassay. First, stock 1000 mg/L containing Cefixime prepared, each bacterium (gram-positive gram-negative), 5 samples from reactor collected under...

Abstract Among the pharmaceutical compounds, tetracycline is second most common group of antibiotics in terms production and consumption worldwide, which their entrance to hospital, domestic industrial wastewaters pollute water sources environment finally leads antibiotic resistance. The aim this study was determine efficiency electrochemical processes, Fenton, electro-Fenton (EF) sono-electro-Fenton (SEF) separately using Graphite (G)/β-PbO 2 anode remove from aqueous solutions. First,...

Background and Objectives: he occurrence characteristics of Extended Spectrum- AmpC-β-lactamase producing Enterobacterales (ESBL-PE AmpC-PE) in an urban wastewater treatment plant (WWTP) were investigated. Materials Methods: A total 30 samples collected from all sections WWTP. isolated identified using standard microbiological tests. The antibiotic resistance profile was determined by the Kir- by–Bauer disk diffusion method. Phenotypic screening for ESBL-PE AmpC-PE isolates performed...

Background: Corrosion and scaling are major problems in the drinking water facilities causing such as loss, recued life of facilities, pipe punctures, clogging pipes, pressure loss distribution system. This study aims to determine corrosion potential system Meshginshahr, Ardebil, Iran. Methods: descriptive cross-sectional was conducted during two seasons (summer winter) 2019. A total 20 samples, which were obtained by averaging 100 analyzed using Langelier Saturation Index Ryznar Stability...

The carbapenem-resistant

Abstract The aim of the present study was to evaluate efficiency advanced oxidation processes (electrochemical, Fenton and electro-Fenton) in removal oxytetracycline using SS316 SS316/β-PbO 2 anodes. This performed experimentally on a laboratory scale 250 mL reactor. First, experiments were designed for electrochemical process central composite design, optimal conditions variables pH(3.53), electric current density(3.85mA/cm ), initial concentration (20mg/L) electrolysis time (42.35min)...

Corrosion and scaling is one of the major daily problems in operation water facilities causes such as loss, shortening life facility, creating holes pipes, clogging, pressure loss supply network. Therefore, purpose this study to determine corrosion potential drinking sources Meshginshahr. This descriptive cross-sectional was conducted during two seasons (summer winter) 2019. A total 20 samples which were obtained by averaging 100 samples, analyzed resources using Langelier Ryznar indices The...

In this experimental study, alum adsorbent was synthesized using an electrochemical process consisting of aluminum (anode) and iron (cathode) electrodes in a 1 L cylindrical reactor.The structure the investigated transmission electron microscopy, scanning X-ray diffraction, Brunauer-Emmett-Teller techniques.Adsorption experiments were evaluated with four input parameters such as pH (4-9), nanoparticles dosage (0.01-0.05 g/L), initial concentration tannic acid (10-80 mg/L), contact time (5-50...
