a study was performed in hybrid up flow anaerobic sludge blanket (huasb) and anaerobic filter (af) reactors to compare the start-up time and optimum hrt required for the treatment of poultry slaughterhouse wastewater under similar loading conditions. initially, the reactors were started at an olr of 0.77 kg cod/m3.d and hrt of 36 h. loading rates were increased by reducing hrt 24, 16, 12, 10 an...
the significance of the study of deixis was then mentioned. the purpose of the present study from the outset was to provide a comprehensive overview of all kinds of deixis in persian, describing and defining each in true while considering them structurally and semantically. chapter two consisted of two main parts. a review of the english studies in this respect, besides presenting persian liter...
Anaerobic baffled reactor (ABR) is one of the widely used wastewater treatment systems in industrial and domestic applications. In this study, effect dilution rates (5%, %10, 20%, 50%) on landfill leachate (LFL) with regard to chemical oxygen demand (COD), color, nitrogen compounds, organic matter was investigated. The maximum removals were observed when rate 20% (v:v,1:5). COD, dissolved carbo...
in this paper, startup performance of upflow anaerobic hybrid reactor and upflow anaerobic sludge blanket reactors in anaerobic treatment of distillery spentwash has been studied under identical conditions of operation. various effluent characteristics like ph, electrical conductivity, chemical oxygen demand, biochemical oxygen demand and total solids and other process parameters like biogas p...
The mechanism of biomass granulation in anaerobic reactors has been widely studied in the hope that this could be helpful in manupulating the rate and extent of granule formation, particularly in wastewaters that show little intrinsic propensity to granulate (e.g. fat and oil containing effluents). Similarly, in this study, sets of sludge samples were taken from Normal Fed Anaerobic Baffled Rea...

in recent years, there has been a growing interest among researchers to investigate the relationship betweenteacher self-efficacy and classroom behavior management, especially students misbehavior. therefore, this study aimed to comparatively investigate english and arabic teachers’ use of different behavior managementstrategies, their self-efficacy, and their success in an iranian context. th...
This present paper reports a study of the efficiency of an anaerobic Baffled Reactor (ABR) composed of three chambers working as the first stage of a biological treatment system for swine wastewater, over a period of 116 days. The average value of the volumetric organic loading rate (VOLR) was 17.8 kgCODtotal m d, the biological organic loading rates (BOLR) based on total and filtered COD influ...
abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...
In a lab-scale upflow anaerobic sludge blanket reactor inoculated with granular sludge from a full-scale wastewater treatment plant treating paper mill wastewater, methanethiol (MT) was degraded at 30 degrees C to H2S, CO2, and CH4. At a hydraulic retention time of 9 h, a maximum influent concentration of 6 mM MT was applied, corresponding to a volumetric loading rate of 16.5 mmol liter-1 day-1...
