For this purpose, a laboratory-scale MBR was constructed and operated to treat leachate with a chemical oxygen demand (COD) of 9000-11,000 mg/l, a 5-day biochemical oxygen demand (BOD5) of 4000-6,000 mg/l, volatile suspended solids (VSS) of 300-500 mg/l, total nitrogen (TN) of 2000-6000 mg/l, and an ammonia-nitrogen (NH3-N) of 1800-4000 mg/l.

Dissolved Air Flotation (DAF) systems are designed to remove suspended solids (TSS), biochemical oxygen demand (BOD5), and oils and greases (O&G) from a wastewater stream. (poweronline.com)
Additional testing measured total solids (TS), moisture, wet weight per cow per day, COD (chemical oxygen demand), BOD5 (biochemical oxygen demand during decomposition occurring over a 5-day period), pH, nitrogen and phosphate levels. (biocycle.net)
Suspended solids1
Secondary treatment consists of three high-rate activated sludge (HRAS) tanks and two BTFs to nitrify and remove residual BOD5 and suspended solids. (water-technology.net)
Effluent1
Research proves that higher concentrations of sodium sulfite can degrade beneficial dissolved oxygen levels, increase BOD5 and reduce overall effluent quality. (tramfloc.com)
Sludge1
Thus, it was a significant challenge to reduce the BOD5 in the faecal sludge treatment plant for its ultimate disposal. (snv.org)
BOD71
BOD7 data has been recalculated into BOD5 data. (europa.eu)
Efficiencies1
SRT and HRT did not significantly influence on the COD and BOD5 removal efficiencies. (uwaterloo.ca)
Removal1
Bench-scale testing was conducted to quantify the effectiveness of BOD5 removal utilizing an aerobic biological contact reactor and ballasted flocculation/settling. (wwdmag.com)
Total1
BOD5 multiplied by 1.16), 20 kg/d for total phosphorus and 10 t/d for COD. (pulpandpapercanada.com)
Studies1
Two independent studies were performed to determined COD and BOD5, according to the internal method A-15, Biological Oxygen demand (BOD5), similar to the OECD guidelines. (europa.eu)
Biochemical2
Weekly samples were analyzed for 5-d biochemical oxygen demand (BOD5), total suspended solids (TSS), total Kjeldahl N (TKN), total ammoniacal N (TAN), total P (TP), and Escherichia coli. (umn.edu)
The wetland was designed to treat an average daily flow of 1305 L (345 gal), and it must meet a regulatory standard of 30 mg/L for both total suspended solids (TSS) and biochemical oxygen demand BOD5. (brikbase.org)
Discharge1
Decreasing the TSS loading on the system by adding a settling basin or pre-filter may enable the system meet BOD5 and TSS discharge concentration limits throughout the year. (brikbase.org)
Parameters1
The following parameters are eliminated: BOD5, Floating Matter, Sediment Solids and Fecal Coliforms. (basham.com.mx)
Solids1
Due to physical processes the water is filtrated mechanically, while microbiological activity in the filter media leads to removal of nutrients, BOD5 and total suspended solids. (slu.se)
Biological3
It usually reflects the amount of oxygen consumed in five days by biological processes breaking down organic waste (BOD5). (cdc.gov)
MacLaren typically utilizes 22 to 24 of the 41 Aqua-Jet aerators at any one time for biological treatment of its pulp waste and to reduce BOD5 and TSS to required levels. (watertechonline.com)
As would be expected for optimal wastewater treatment, biological oxygen demand (BOD5) was reduced by at least 63% during nano-scale Cu exposure, indicating normal function. (nih.gov)
Temperature1
During the five-day BOD or BOD5 test process, the BOD bottle is used for incubating diluted samples under the 20 °C or 68 °F of temperature. (wikipedia.org)
Limits1
The system achieved concentration limits for BOD5 during the growing season. (brikbase.org)
System1
The changes in TOC and BOD5 demonstrate that the system was improperly treating waste. (nih.gov)
Reduce1
Their main purpose is to reduce BOD5 concentrations to suitable levels. (ampc.com.au)
Total1
The copper fungicide, Cu(OH)2, caused a 57% increase in total organic carbon (TOC), which is well above the typical range for septic systems and also corresponded to increased BOD5 during the majority of the Cu(OH)2 exposure. (nih.gov)
