ANAEROBIC TREATMENT OF HIGH SALINE PHARMACEUTICAL WASTEWATER
… content are two major challenges for biological treatment of saline industrial effluents. In this study, various anaerobic technologies were attempted including anaerobic sequencing batch reactor (AnSBR), up-flow anaerobic sludge blanket (UASB) and anaerobic membrane bioreactor (AnMBR), and …

Anaerobic treatment of a paper plant effluent
… objective of this study was to investigate the anaerobic biological treatment of an organic-bearing wastewater from a particular paper manufacturing process at laboratory scale. The process produces paper by re-pulping waste paper. Effluent from the process has a Chemical Oxygen Demand (COD) …

Low strength wastewater treatment using emerging anaerobic treatment processes
… OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Anaerobic treatment is a promising and energy saving process for low-strength wastewater treatment. Roles of half saturation constant (Ks) and maximum specific growth rate (umax) in anaerobic treatment systems, however, are often overlooked. This …

A mathematical model of a high sulphate wastewater, anaerobic treatment system
… heavy metal concentrations. One promising treatment technology is biological sulphate reduction in anaerobic reactors. During anaerobic treatment, sulphate is reduced to sulphide and alkalinity is generated, raising the pH and precipitating many of the heavy metals. The process requires a …

Collection, analysis, and utilization of biogas generated by the anaerobic treatment of crab processing wastewater
Energy recovery from the anaerobic treatment of crab processing wastewater was investigated. Biogas from two laboratory-scale, upflow anaerobic filters (Systems A and B) was collected and analyzed to determine percent by volume composition of methane (CH₄), carbon dioxide (CO₂), and hydrogen …

Advanced anaerobic treatment for energy recovery and improved process economics in the management of biorefinery wastewaters
… analysis and evaluation of the wastewater treatment process and more specifically, the anaerobic treatment system design. To this effect, this study began with a comprehensive wastewater characterization and composition analysis to verify its suitability for digestion. From there the …

Pilot-scale study on anaerobic/aerobic treatment of a textile dye wastewater
… constructed at the Martinsville Publicly Owned Treatment Works (POTW) in Martinsville, Virginia, to evaluate an anaerobic/aerobic treatment scheme for removal of color from textile dye waste waters mixed with municipal sewage. Treatments were evaluated with and without addition of a reducing …

Combined anaerobic-aerobic treatment of a simulated textile effluent
… a simulated textile effluent (STE) with combined anaerobic aerobic treatment. A simple simulated cotton processing effluent was generated that was similar to real effluents in terms of COD, BOD, COD:BOD, pH and TSS. An upflow anaerobic sludge blanket reactor (UASB) was more effective in treatment …

Treatment of blue crab processing wastewater using Upflow Anaerobic Sludge Blanket (UASB) and air stripping technologies
… and total Kjeldahl nitrogen (TKN). Biological treatment of the wastewater releases high concentrations of ammonia. In this study, UASB treatment of crab cooker wastewater was evaluated, in terms of COD and TSS reduction, and compared with previous anaerobic treatment efforts. Additionally, UASB …

Color removal in textile dye wastewaters by means of coagulation
… formidable and somewhat insusceptible to removal treatment processes. Recent governmental regulations have made it necessary to remove most color before discharging the treated wastewater to surface waters. Chemical coagulation is successful in some cases at reducing wastewater color to acceptable …

Adsorption and dechlorination of chlorophenols under acidogenic conditions
Anaerobic treatment of chlorinated compounds often encounter stability problem due to methanogens' sensitivity to chlorinated compounds. This thesis proposed the separation of the anaerobic process into acidogenic and methanogenic phase which aims to utilize the acidogenic phase to induce …

Biological Treatment of a Synthetic Dye Water and an Industrial Textile Wastewater Containing Azo Dye Compounds
In this research, the ability of anaerobic and aerobic biological sludges to reduce and stabilize azo dye compounds was studied. Synthetic dye solutions and an industrial textile wastewater were both treated using anaerobic and aerobic biomass, separately and in sequential step-treatment processes. …

Stoichiometry and kinetic modeling of an anaerobic baffled reactor, The
The current domestic wastewater treatment paradigm is centered around aerobic biological treatment processes. The aerobic treatment of wastewater requires a substantial energy input, while effectively wasting a significant portion of the potential chemical energy found in the raw wastewater. This …

Anaerobic/aerobic pretreatment of blue crab (Callinectes sapidus) cooker wastewater
… cooking of blue crabs presents a difficult treatment challenge. COD concentrations in the range of 15,000 to 30,000 mg/L are found in this wastewater, with TKN concentrations above 2,000 mg/L. Direct discharge of the wastewater, which is currently allowed, adds nutrients to the Chesapeake …
