  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 reduction tests

  In industrial manufacturing companies, before a new process comes on-line, it is important to measure the toxicity of the effluent stream. This is especially the case for companies who treat their own waste. From the toxicity value (EC50) obtained, it may be a cost-effective solution to simply discharge the effluent to the treatment works at a slow and defined rate to minimise damage to the activated sludge. Following a period of acclimatisation it is often possible to increase feed rates to the plant and this...

  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 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...
