  • With BOD, What You See is Often Not What You Get: The Difficulty with Accurate Testing for BOD in Industrial Stormwater Runoff.

    Biochemical oxygen demand (BOD) is a measure of the amount of dissolved oxygen used by microorganisms to break down organic material in a sample of water. As they do so, these microorganisms deplete the amount of dissolved oxygen in the water, which can be deadly for aquatic species like fish that rely on dissolved oxygen to live. Because of this hazard to aquatic life, BOD is considered an ...

  • Gresham Wisconsin Bio-Dome Pilot Study 2010

    This article explores the results obtained from a mobile pilot unit in Gresham Wisconsin during the winter of 2010.  The pilot unit was installed to October 2010 and ran through April of 2011.  During the course of the study, the Bio-Dome was tested under various loading conditions and operating conditions.  Samples were taken for both the influent and effluent of the lagoon. ...

  • Utilizing predictive BOD via the peCOD method for Nutrient Optimization in Wastewater Treatment

    Canfor have been successfully employing the fast peCOD chemical oxygen demand (COD) method for improved effluent control and savings at the Prince George, BC Mills.  Having realized improved efficiency, the next step was to optimize nutrient feeds.  Canfor have developed a PeCOD/BOD correlation for the basin inlet sample point to predict inlet BOD concentration. From there a BOD:N:P ...

  • Degradation of phenolic wastewaters by solar/TiO2 and solar/TiO2/H2O

    The application of Advanced Oxidation Processes (AOPs) (solar/TiO2 and solar/TiO2/H2O2) to treat phenol, o-cresol, m-cresol, and p-cresol wastewaters was investigated. The experiments were performed in batch solar reactor using TiO2 as catalyst. The effect of the hydrogen peroxide concentration on the degradation kinetics was evaluated in the range of 0.15?1.5 ...

  • The effects of nutrient limitation (nitrogen and phosphorus) on BOD removal from post-coagulated Pinus radiata sulfite pulp and paper mill wastewater in a baffled aerated stabilisation basin–laboratory pilot scale study

    The use of coagulation and flocculation for tertiary treatment of pulp and paper mill effluent was investigated, where the evaluation was based on the removal of nitrogen (N), phosphorus (P) and BOD from post-coagulated wastewater. The study was undertaken on laboratory scale aerobic stabilisation basins (ASB). Two post coagulated (alum) wastewaters were studied, where the BOD:N:P ratios were ...

  • BLOOM – Real-Time Monitoring Brief - Case Study

    PeCOD® is a patented technology that can determine COD by measuring photocurrent charges originating from oxidation of the organic contaminants present in a water sample. Three PeCOD® analyzer units were implemented at three different facilities, representative of key food and beverage sub-sectors–a winery, a bakery and a brewery–to undertake “real-time” ...

  • SMF4 case study 2

    Sewer Misconnection Survey Date: March 2010 Location: Edgebaston Birmingham UK Purpose: To test the application of the SMF4 portable fluorimeter in the detection and quantification of organic pollution from faecal matter in Surface water Sewers. Background STS was invited independently by the Environment Agency and Severn ...

  • Biologically Engineered Biofilm Modifications for the Enhancement of Collection System Transformations and Impacts on BNR Wastewater Treatment

    ABSTRACTIncreased influent RBCOD and heterotrophic plate counts coincided with the start of bioaugmentation in this study. Observed influent sulfide levels were also lower duringbioaugmentation. RBCOD increases could potentially improve biological phosphorus or nitrogen removal. Lowered sulfides in the influent could lower corrosion and odors in the collection system ...

  • Two environmental laboratories, 1 private and 1 government, optimize automation and ROI with investment in BOD/Titrate duo (case study)

    MANTECH INC. is a leading manufacturer of automated multi-parameter, titration, BOD and COD laboratory instruments. Both a Private and Government Environmental Laboratory required optimized return on investment for both automated BOD/CBOD and automated multi-parameter systems. They each invested in the MANTECH BOD/Titrate Duo. Background Each laboratory identified ...

  • Fruit Cannery

    This facility cans peaches and pears and wanted to investigate the reduction in BOD and TSS using the Floccin Agents. Samples were made in the off season using 2/3 by weight of peach to 1/3 pear with a total amount of 100 grams in 2,000 ml (5% by weight to simulate the wastewater generated from the facility). The samples were flocculated with Floccin J at a dosage of 0.25 gram/1,000 ml (250 ...
