  • Measuring Short-Term BOD

    Measurement of oxygen uptake rates in activated sludge processes is essential to their satisfactory operation. Traditionally, oxygen uptake rates (OUR) have been determined by using a dissolved oxygen probe to measure the change in dissolved oxygen in a BOD bottle. While this method is rapid, it provides only a snapshot, at a single point in time, of the oxygen uptake rate reaction in a treatment ...

  • Results of trials to remove BOD/COD from effluent arising from cellulosic fibre production case study

    A man-made natural fibre producer had produced a new high strength, fibrillated cellulosic fibre derived from wood pulp destined for use in garment manufacture. As a result of the IPC authorisation attached to the production of this product it became necessary to establish the biodegradability of various effluent streams leaving the production plant. In order to evaluate the feasibility of ...

  • Streamlining Wastewater Treatment in Poultry Processing: Michigan Turkey and Lyco Team Up to Provide a Showpiece for Reducing BOD and TSS Levels

    With the steady increase in poultry processing rates there has been a corresponding increase in wastewater pollutant concentrations. Despite mechanical improvements in wastewater treatment, many poultry processors continue to pay unnecessarily high fees for municipal water discharges. $100-million-annual processor, Michigan Turkey Producers, in conjunction with Lyco Manufacturing, has set up a ...

  • Types of Environmental Standards

    Different kinds of environmental standards can serve quite different purposes in environmental policy. This note outlines these differences Ambient Standards Ambient standards set maximum allowable levels of a pollutant in the receiving medium (air, water and soil). Ambient standards can offer a simple method of establishing priorities since areas (or stream lengths) which ...


  • Viltra IWOX systems engineered by DMT - The next standard in small scale wastewater treatment

    Abstract Both technology and environmental awareness drive legislation for wastewater treatment. Now, the leap from 20/30 (BOD: Biological oxygen demand, mg/l / SS: suspended solids, mg/l) to 10/10 or even 5/5 is possible due to a different design approach. For years, the sewage treatment plant market was dominated by systems from (septic) tank suppliers, but now an engineering company ...

  • Factors affecting the performance of a single-chamber microbial fuel cell-type biological oxygen demand sensor

    Microbial fuel cells (MFCs) are devices that exploit microorganisms as biocatalysts to degrade organic matter or sludge present in wastewater (WW), and thereby generate electricity. We developed a simple, low-cost single-chamber microbial fuel cell (SCMFC)-type biochemical oxygen demand (BOD) sensor using carbon felt (anode) and activated sludge, and demonstrated its feasibility in the ...

  • Northwest’s Hood River Juice Company Hood River, OR case study

    The Problem: Hood River Juice was building a new process facility and needed to construct a wastewater treatment plant to meet their surcharge requirements for BOD and TSS. The goals and objectives were to minimize operator attention and achieve results that were sustainable. The Solution: BioprocessH2O provided a bioFAS Mobilized ...

  • Performance of a constructed wetland for treating farm-yard dirty water

    Constructed wetlands (CWs) have been used to treat agricultural effluents with varying success especially with respect to their operational efficiency in winter and ability to retain phosphorus. Dirty water (DW) from dairy farms is a mixture of manure contaminated runoff and milk parlour washings with a highly polluting biochemical oxygen demand (BOD) ≤3,000 mg/L. The initial performance a CW of ...

  • The Operation of Anaerobic Lagoons

    The operation of the anaerobic lagoon adjacent to Isfahan Wastewater Treatment Plant was studied over a 12- month period. The rate of organic loading, BOD and SS removal efficiencies and their relationships with organic reductions and ambient temperature were studied. A high correlation was found to hold among temperature, organic loading rate, and BOD 5 removal. A correlation coefficient of 87% ...


  • ENHANCING THE PERFORMANCE OF OXIDATION DITCHES

    Oxidation ditches are very popular wastewater treatment processes for small to mediumsized municipalities that have to meet stringent water quality standards. Oxidation ditches provide cost-effective treatment while requiring relatively simple operational skills. Because carbonaceous BOD removal, nitrification, and de-nitrification can be accomplished within a single reactor, the process can ...

  • Feasibility of UASB/trickling filter systems without final clarifiers for the treatment of domestic wastewater in small communities in Brazil

    The paper analyses the concept and performance of different configurations of compact UASB/TF systems, without the final clarification stage, in relation to the removal of organic matter. The experiments were carried out in two sets of UASB/TF systems operating without secondary clarifiers, as follows: (i) four shallow (2.50 m height) TFs, each one filled with a different packing material; and ...

  • Risk analysis of seasonal stream water quality management

    Seasonal discharge programs, which take advantage of temporal variation of stream assimilative capacity, are cost effective. However, these seasonal discharge control programs should not increase the risk of water quality violations. A method is presented to estimate the allowable pollutant loads under both seasonal and non-seasonal discharge control programs for a single discharger that ...
