    Oxygen Monitoring from Aerobic and Anaerobic for determination of biodegradation kinetics by respirometry

    Intrinsic kinetic tests involve adding relatively high concentrations of organic substrate to small concentration of acclimated microorganisms so that the COD/VSS ratio typically is greater than 10. Kinetic parameters are then determined by non-linear modeling using well-known relationships between biological growth and oxygen uptake.

    Oxygen monitoring from aerobic and anaerobic for biomass activity tests

    Pulse-Flow respirometers can be used to assess biomass activity for aerobic and anaerobic reactions. In aerobic tests, cultures are combined with nutrients, trace minerals, and an organic substrate – such as acetic acid or ethanol. The maximum oxygen uptake rate reflects the amount of active biomass in the test culture.

    Oxygen monitoring from aerobic and anaerobic for toxicity test

    Toxicity of pure chemicals is assessed using respirometers by adding increasing concentrations to an active culture. The concentration at which oxygen uptake or gas production begins to decrease is known as the “threshold toxicant concentration.”

    Anaerobic water purification systems for anaerobic COD removal

    In anaerobic treatment, bacteria convert organic compounds (COD) to biogas in an environment without oxygen. Not only do the bacteria remove contaminating compounds from the effluent, thereby reducing discharge costs, they produce green energy at the same time.

  • Biological waste water treatment plants solutions for beverage industry

    Due to the diversity of products in the beverage industry, there is also a great variation in waste water composition (flow and load) from this type of industry. This requires special attention and tailor made solutions for the design of a waste water plant for this industry.

  • Waste water respirometry solutions for process optimisation

    Respiration rate of activated sludge has been recognised as a key controlling element in the modelling of process control, by the International Water Association Task Group. Actual respiration rate of the sludge in the aeration tanks, as well as the endogenous and maximum respiration rates are variables that indicate the rate of BOD removal and aeration requirements. The maximum respiration rate is also closely linked to the Critical Oxygen Concentration point, that is, the point at which diffusion over the...

  • Aquatic Respirometry

    Aquatic respiration can be simply yet accurately measured on intact, live organisms using a variety of Strathkelvin Instruments respirometry systems. As with all of our respirometry systems, an aquatic system would comprise of an oxygen meter (either 782 or 928), one or more, high precision, 1302 oxygen electrodes (link) and a respiration chamber to house the organism. The researcher also has a choice of measuring respiration rates via closed or flow-through respirometry. Both closed and flow-through systems...

  • Energy from the anaerobic wastewater treatment for the Food and Beverage industrial sector

    Industrial wastewater characterized by an high COD content are an interesting renewable source for the Food and beverage industrial sector which can have them readily available from their industrial processes. The COD contribution in the wastewater can be easily converted in biogas and then in green energy to reuse inside the factory as both electrical energy and thermal energy. This process can be applied with the installation of the UASB technology, implemented by Hydroitalia - Colsen in new and existing plants.

  • Biological waste water treatment plants solutions for bio ethanol distilleries

    The waste (water) streams from the production of (bio) ethanol or ethanol spirits are generally very suitable for anaerobic treatment, due to their organic compounds.

  • Waste water respirometry solutions for toxicity testing

    If industrial wastewater entering a treatment works contains toxic components the rate of biodegradation will be inhibited or stop completely. This can result in failed consents and will certainly give rise to operational problems. Visible indications include deflocculation, bulking and the appearance of filamentous bacteria. Sometimes, there are no visible effects. When the sludge bacteria are inhibited, there is the possibility of toxicity carryover in the effluent that is discharged to receiving waters. With...

  • Waste water respirometry solutions for toxicity tracking

    If toxicity is identified in a mixed sewage entering a treatment works, the problem for the plant manager is to track and identify the source of the toxicity. This can be done by sampling the effluent stream at various points in its length. By working in a logical sequence back up the sewer network the number of samples can be minimised. This type of testing should be rigorously enforced for new product introduction by a waste producer, as well as sampling the effluents directly at source. The samples would be...

  • Waste water respirometry solutions for monitoring activated sludge health - sour test

    Respiration rate monitoring of Antwerp treatment works showed periods when the activated sludge was up to 40% inhibited, with resultant sludge washout episodes. Using the Health monitoring test, a pattern of ‘normal’ respiration rates for a plant can be determined. Lower respiration rates will alert the treatment works to a chronic toxicity problem, allowing corrective actions to be taken. Toxicity monitoring can now be carried out on a routine daily basis, at all treatment works receiving potentially toxic...
