“…However, in some European Nordic and Baltic countries, a 7 days period at 20°C (BOD7), also described by the EN 1899-1 European standard, was adopted [4]. In India, the standard method IS 3025-44 opts for a "3 d / 27°C" incubation period resulting in similar BOD values than the "5 d / 20°C" standard method.…”

“…However, for an efficient management of biological treatment processes which requires highly responsive analytical tools, a 5 days incubation period is too long. Moreover, the current BOD measurement methods are really labour-intensive as well as time-and space-consuming [3][4].…”

“…However, the analytical methods currently available for the BOD measurement drastically suffer from a lack of operational suitability. These methods are lengthy and tedious while the operation of modern STP requires a high responsiveness through fast and easy-to-use analytical tools [3][4]. In the last decades, the biological processes for wastewater treatment have substantially changed to match the stricter and stricter effluent quality standards decreed by the European authorities.…”

Abstract. Knowing the quantity and biodegradability of wastewater organic matter (OM) is really essential for the optimization of modern biological treatment processes, particularly when considering the highly challenging context for sewage treatment plant operators. However, the current standard methods for wastewater characterisation, as for 5-days biochemical oxygen demand (BOD5) measurement, OM fractionation analysis and bacterial inhibitor detection, show very poor suitability for routine operational use. In this paper, the efficiency of the commercial Enverdi® method (fluorimetric respirometry) for such analytical applications is investigated, especially for the BOD5-equivalent measurement in municipal wastewater samples. The result of numerous experiments showed that the BOD5 values obtained from the alternative Enverdi® method and the main standard methods are statistically equivalent. The analytical performances of the Enverdi® method was found similar to the standard BOD5 method specifications and perfectly matched the French regulatory requirements in force. The regulatory acceptance of this method is presently under consideration. Such an outlook would be really valuable for end-users given the main advantages of this analytical solution which is time-and space-saving, user-friendly and financially competitive. In addition to BOD5 measurement, the fluorimetric respirometry displayed very promising abilities for the OM fractionation and the detection of bacterial inhibitors in wastewater.

“…It has, however, the limitation of being time-consuming, and consequently it is not suitable for online process monitoring. Thus, it is necessary to develop an alternative method that could circumvent the weakness of the conventional BOD test [127]. Fast determination of BOD could be achieved by biosensor-based methods.…”

“…A common feature of these sensors is that they consist of a microbial film that can biooxidize the organic substrate to be quantified, sandwiched between a porous cellulose membrane and a gas-permeable membrane as the biological recognition element. The response is usually a change in concentration of dissolved oxygen or other phenomena such as light emission [127]. Most BOD sensors rely on measuring the bacterial respiration rate in close proximity to a transducer, commonly Clarktype (an amperometric sensor for measuring dissolved oxygen developed by Clark in 1956 [127]).…”

Biosensors can be excellent analytical tools for monitoring programs working to implement legislation. In this article, biosensors for environmental analysis and monitoring are extensively reviewed. Examples of biosensors for the most important families of environmental pollutants, including some commercial devices, are presented. Finally, future trends in biosensor development are discussed. In this context, bioelectronics, nanotechnology, miniaturization, and especially biotechnology seem to be growing areas that will have a marked influence on the development of new biosensing strategies in the next future.

Biochemical oxygen demand (BOD) is the most important and widely used environmental index for monitoring organic pollutants in wastewater. The current international standard method is the five‐day BOD assay (BOD 5 ). The test measures the amount of dissolved oxygen required for the microbial oxidation of carbonaceous organic material under specified conditions. The test has its widest application in measuring waste loadings to treatment plants and in evaluating the BOD‐removal efficiency of such treatment systems. Practical difficulties exist associated with the BOD 5 test, including sensitivity to temperature and oxygen concentration, impact of toxins, lack of stoichiometric validation, and the need to dilute samples. The test is labor intensive with variable results, but the major drawback continues to be the five‐day measurement time. For all its shortcomings and the availability of a number of related measurement techniques, the BOD 5 assay remains the preferred test for reporting the oxygen requirements of wastewaters, effluents, and polluted waters, in part, because of its international regulatory status, but also because it uniquely simulates the microbial decomposition of organic wastes in the environment, thereby approximating the response of natural ecosystems.
