a pilot anaerobic filter was used to remove cod from babolsar fiberboard production wastewater. the anaerobic filter was packed with ceramic packings and operated at different organic loading rates of 2.4 and 8 kg cod/m3 /day, in 20, 10 and 5 days hydraulic retention time (hrti), respectively. the reactor achieved cod removal of 80.3%, 81% and 79% for hrt 20, 10 and 5 days, respectively. in add...

Abstract: One of the domestic wastewater management systems developed in Banda Aceh City is a settlement-scale centralized treatment plant, also known as Communal WWTP system, with an anaerobic baffled reactor (ABR) and filter (AF) configuration. This study aims to examine quality effluent from communal WWTPs city Aceh. Measurements contents pH, BOD, COD, TSS, Ammonia, Total Coliform were carri...

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...

Abstract Numerical simulations explore a possible tightly baffled, long-legged divertor (TBLLD) concept in future upgrade of the Tokamak à configuration variable (TCV). The SOLPS-ITER code package is used to compare exhaust performance several TBLLD configurations with results from unbaffled and baffled TCV configurations. investigated TBLLDs feature range radial gaps between separatrix baffles...
