The negative energy balance of wastewater treatment could be reversed if anaerobic technologies were implemented for organic carbon oxidation and phototrophic technologies were utilized for nutrient recovery. To characterize the potential for energy positive wastewater treatment by anaerobic and phototrophic biotechnologies we performed a comprehensive literature review and analysis, focusing o...

The present study investigates the influence of individual and combined hydrogen peroxide and thermal pre-treatment of waste activated sludge on anaerobic digestion. For so doing, it employs anaerobic batch reactors in the mesophilic conditions. For comparison, soluble fractions of organic matter, biogas production, biochemical methane potential, removal of chemical oxygen demand (COD), and vol...

preterm premature rupture of membrane(PPROM)is one of the serious problems during pregnancy.the aim of this study was to determine the probable relation between group B streptococal and anaerobic infections and PPROM.for this porpust 100 pregnant women with preterm rupture of membrane were selected.in the case group the prevalence of B-hemolytic streptococcal and anaerobic microorganisms was de...

Changes in the availability of skilled laboratory personnel, new technologies, and the financial environment will all influence the practice of diagnostic microbiology in the near and more distant future. Because of the special expertise needed for the accurate identification of anaerobic bacteria, the ability to diagnose anaerobic infections may decline as a consequence of these changes. Physi...

the effect of hydraulic retention time in a range from 1.0-5.5 days was evaluated in a laboratoryscaleanaerobic fixed bed reactor packed with a hybrid material composed of tire rubber and zeolite. underthese conditions, cod removal efficiencies varied from 28.3% to 82.1%, respectively. over the more than 6months of operation, no clogging was observed. the results obtained demonstrated that this...
