we evaluated the efficacy of a full-scale combined biophysicochemical system for treatingmolasses-based bioethanol wastewater in terms of organic substances, nutrient, and dark brown color removal. the main organic removal unit, i.e., the upflow anaerobic sludge blanket (uasb) reactor, achieved 80.7% removal and 4.3 nm3 methane production per cubic meter of wastewater with a hydraulic retention...

background: the purpose of this study was to investigate the efficiency of flat sheet membrane bioreactor (fs-mbr) in bod 5 and cod removal of isfahan south municipal wastewater treatment plant. methods: in this study a submerged fs-mbr, with 140 liters volume was fed using microfiltration membrane (mf) during 109 days and hydraulic retention time of 20 hours. findings: the mbr application in m...

Abstract: Horticultural substrates, also referred to as growing media, potting soils and gardening or soilless substrates, are widely used as a basis for vegetable and flower production in horticulture. They are created as a composition of different ingredients (bog peat, organic residuals, coir, perlite and other components). Hydraulic properties such as water storage capacity, air capacity, s...

pregabalin (prg) is a new antiepileptic drug and aceclofenac (ace) is a potent non-steroidal anti-inflammatory drug. these drugs in combination are used for treatment of partial seizures and neuropathic pains. a simple and precise assay method by rp-hplc was developed and validated for estimation of prg and ace in acenac-n tablet. analyses of commercial tablet, acenac-n were performed using jas...

in this research, a 2d laterally averaged model of hydrodynamics and water quality, ce-qual-w2, was applied to simulate water quality parameters in the ilam reservoir. the water quality of ilam reservoir was obtained between mesotrophic and eutrophic based on the measured data including chlorophyll a, total phosphorus and subsurface oxygen saturation. the ce-qual-w2 model was calibrated and ver...

+ − + + + → + H 2 O H NO O 5 . 1 NH 2 2 2 4 (1) In the SHARON (Single reactor High activity Ammonia Removal Over Nitrite) process, partial nitrification is establishing by working at high temperature (about 35°C) and maintaining an appropriate sludge retention time (SRT). The SHARON reactor is operated as a continuously stirred tank reactor (CSTR, chemostat) without biomass retention, so the sl...

the evaluation of treatment characteristics and sludge properties of an upflow anaerobic sludge blanket (uasb) process was investigated using a pilot-scale 1.15 m3reactor. the uasb, inoculated with digester sludge, was operated at a hydraulic retention time of 8 h at sewage temperatures ranging from 10.6 to 27.7 °c for more than 1100 days. the stable removal efficiencies for total codcr and ss...
