  • Biodegradation Tests for Wastewater Samples

    Biodegradation Tests for Wastewater Samples Biodegradation tests usually involve comparison of the oxygen uptake of a test sample – or gas production for anoxic or anaerobic tests – to that for a readily biodegradable control substrate (usually acetic acid, ethanol, or aniline). While biodegradation characteristics can vary among chemical types and wastewater sources, typical patterns are shown ...

  • Biodegradability of industrial textile wastewater – batch tests

    Following new trends we applied oxygen uptake rate (OUR) tests as well as long-term tests (in two batch bioreactors systems) in order to assess the biodegradability of textile wastewater. Effluents coming from a dyeing factory were divided into two streams which differed in inorganic and organic contaminants loads. Usefulness of the stream division was proved. Biodegradation of the low-loaded ...

  • Wastewater Monitoring Series, Part 1: Identifying the Gaps in Conventional Biomass Test Methods in Wastewater

    Biological wastewater treatment systems require living biomass to remove biodegradable contaminants from wastewater.  Effective treatment is directly dependent on the concentration of healthy biomass. It stands to reason that having an easy method to directly measure the quantity and quality of living biomass would be tremendously beneficial to the operation of biological wastewater ...

  • Test organisms behaviour on municipal and industrial wastewater quality assessment

    Industrial wastewaters quality became a target for the environmental toxicity assessment nowadays. When there are issues with complex effluents for which many chemicals cannot be quantified and/or interactive effects are likely to be significant, the use of bioassays with different test species becomes a more reliable way in the assessment of toxicity. Ecotoxicity evaluation of the several ...

  • Refinery Wastewater

    A refinery was storing wastewater in several tanks and needed to meet the city discharge limits before they were allowed to dispose of the water. The problem was with soluble sulfides (1,000 ppm in the water) as the discharge was 0.5 ppm. Integrated Engineers was contacted to see if they could create a treatment process to reduce the sulfides to discharge limits. Several large water treatment ...

  • Anaerobic BMP and ATA Tests

    Anaerobic BMP and ATA Tests Biochemical Methane Potential (BMP) tests involve addition of test chemicals or wastewater samples of concern to an anaerobic culture that is contained within a sealed vessel. Methane or total gas production are measured over periods ranging from 1 to 60 days without addition of new chemical or wastewater sample. Modern BMP tests usually involve multiple additions of ...

  • Asset Management Condition Assessment for Stockton: To Test or Not To Test

    ABSTRACTTo help ensure assets are maintained to high standards, a 20-year service contact between the City of Stockton and OMI/Thames Water required a condition assessment of all managed assets. Due to the size and complexity of the system, it was not possible to test all assets as part of the condition assessment. A methodology was developed to prioritize assets to be subjected to further ...

  • Interview with Juan Carlos Rodríguez, Production Manager of Wastewater Containerised Plants in Toro Equipment

    Today we talk with our partner – Juan Carlos Rodríguez – about the significance of FAT (Factory Acceptance Testing) in the value chain of Toro Equipment company. What exactly are these tests and why are they so important? Factory Acceptance Testing (FAT) are tests which assess the ...

  • Meat Processing Plant Wastewater

    Traditional Alum & Polymer versus Floccin 1106 The wastewater is currently being treated using conventional chemistry (alum and a polymer). The facility is paying surcharges due to levels of COD at 1,600 ppm and suspended solids TSS) at 500 ppm. The surcharge rates for the local POTW (Publicly Owned Treatment Works) are based on $0.42/lb for TSS and $0.18/lb. for COD. Based on ...

  • Feasibility tests for treating shampoo and hair colorant wastewaters using anaerobic processes

    Wastes from the personal care product (PCP) industry are often high in biodegradable carbon, which makes them amenable to aerobic biological treatment, although process costs are usually high due to aeration inefficiencies, high electricity demand and production of large amounts of sludge. As such, anaerobic treatment technologies are being considered to lower net energy costs by reducing air use ...

  • Anaerobic Biomass Activity Tests

    Anaerobic Biomass Activity Tests The methane production activity of anaerobic sludges is related to the history of the sludge, the biomass yield from the wastewater the sludge has been treating, the fraction of methanogens, and the presence of toxic substances. Best performance can be achieved from an anaerobic treatment plant if the operator measures the Specific Methanogenic Production (SMP) ...

  • Oil in Power Plant Wastewater

    The water is from the operations of a steam power plant located in the Bahamas. The water samples were taken from the Unit 31 (lower oil content) and Tank #3 (a higher oil content). The samples were tested and it was found through the jartesting procedures that the Floccin K was the best choice for floc size and water clarity. The Unit 31 was dosed at 0.5 gram in 1,000 ml and the Tank # 3 water ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...

  • Supporting the Success of Municipalities & Industrial Companies: Genesis Water Technologies and Advanced Electrocoagulation Treatment Technology
