Pilot-scale study on anaerobic/aerobic treatment of a textile dye wastewater
… for: color, total organic carbon (TOC), 5-day biochemical oxygen demand (BODs), chemical oxygen demand (COD), total phosphorus, sulfide, sulfate, total Kjeldahl nitrogen (TKN), ammonia, nitrate, chloride and oxidation-reduction potential (ORP). Nearly 50% color removal was observed during …

Statistical Evaluation of Rapid Biochemical Oxygen Demand Test for Monitoring Municipal Wastewater Quality
… for measuring wastewater quality include the 5-day biochemical oxygen demand (BOD5) and carbonaceous BOD (CBOD5). This thesis presents an alternative wastewater quality test that requires much less time to achieve valid results. This research addresses the precision and statistical validity of …

Evaluation of the subsurface vegetated bed form of constructed wetlands for domestic wastewater treatment
… three detention times (2.6, 3.9, and 5.9 days), two recirculation ratios (0 and 0.5), and two plant species [woolgrass (<i>Scirpus cyperinus</i>) and cattail (<i>Typha latifolia</i>)]. Twelve larger scale SVBs were constructed at the Powell River Project (PRP) site, Wise County, VA. …

A Non-isolated Half Bridge Buck-based Converter For Vrm Application And Small Signal Modeling Of A Non-conventional Two Phase Bu
… oxidized organic compounds (measured as chemical oxygen demand/dissolved organic carbon), and production of more biodegradable byproducts (measured as 5-day biochemical oxygen demand/chemical oxygen demand). Finally, both treatments were found to oxidize larger molecules (>1000 dalton) and produce …

Evaluating Biological Treatment Systems: (i) Moving Bed Biofilm Reactor versus Biological Aerated Filtration, and (ii) Sulfide-Induced corrosion in Anaerobic Digester Gas Piping
… which the systems were evaluated were total 5-day biochemical oxygen demand (TBOD5) and total suspended solids (TSS) of 30 mg/L each. The report is based on a 5-month laboratory -scale study of the two reactors. The MBBR performance depended on the percent of media provided in the reactor and …

Indicators for Minimizing Energy Consumption and GHG Emissions at Wastewater Treatment Facilities
<p>Wastewater treatment facilities around the world use significant amount of energy which contributes to large quantities of greenhouse gas (GHG) emissions. According to the U.S.EPA, nearly 3% of the USA's energy is used to treat wastewater. This consumption is increasing at faster rates with …
