The purpose of this work was to develop a problem-solving approach and simulation tool that is useful for the specification wastewater treatment process equipment design parameters. proposition using an artificial neural network (ANN) numerical model supervised learning dataset then on new investigated. effectiveness assessed by evaluating capacity distinguish differences in To demonstrate appr...

up flow anaerobic sludge blanket (uasb) reactors have been increasingly used for industrial wastewater treatment. because of existing problems in startup step of these reactors, in this research the startup of a uasb in pilot scale and room temperature condition was studied. the total height of uasb reactor was 270 cm and effective height was 240 cm. diameter of the reactor in lower part was 20...

background and objectives: anaerobic bacteria are recognized as important pathogens in surgical infections. however, they are the most overlooked microorganisms by the clinic and the laboratory because of the tedious culture techniques with longer turn-around times. the study was aimed to analyze the frequency of anaerobic bacterial surgical infections and their predisposing factors. materials ...

Complete treatment of sulfur dioxide (SO2) from flue gases in a two-stage process consisting of a biotrickling filter followed by biological post-treatment unit was investigated. The biotrickling filter could remove 100% of influent SO2 from simulated flue gas at an empty bed residence time of 6 s for a concentration range of 300-1000 ppm(v). All the absorbed SO2 was recovered in the biotrickli...

Biological trickling filters are widely used for sewage treatment. This study models a biological filter based on an anaerobic–anoxic–oxic process (A2O–BTF), established by combination of aerobic and anaerobic technology. The performance operational parameters were analyzed using Sumo, commercially available wastewater treatment (WWTP) simulation software. the conventional three-stage (Three-St...
