  • 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...

  • 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...

  • Removal of organic compounds & toxity for wastewater treatment industry

    Federal and State regulatory agencies are increasingly requiring additional water quality testing and controls of the toxicity of discharges to receiving streams. Granular Activated Carbon (GAC) helps meet these pollution regulations. If organic chemicals have been identified as contributing to discharge toxicity, Calgon Carbon Corporation can work with facilities, and their engineering firms, to help meet stringent criteria associated with their NPDES permit. GAC can be employed as a cost-effective treatment for...

  • Waste water respirometry solutions for toxicity based consents

    Water companies, water authorities or publicly-owned treatment works (POTW) need to have some knowledge of the composition of the wastes they it receive. In addition to testing for ammonia and BOD or COD levels, treatment works can license industrial discharges on the basis of concentrations of some of the known toxic compounds. However, it is recognised that very many non-regulated toxic materials still enter the treatment works and reduce the efficiency of biodegradation, and may cause toxic shock. The way is...
