“…The surrogate method presents obvious operational and economic advantages compared to the standard one but its accuracy has to be strictly evaluated. In 2014, a first publication about the statistical comparison of Enverdi-BOD and standard methods based on 109 samples was published (2). This paper presents a similar approach on an extended number of samples, 261 instead of 109, analyzed by 4 laboratories instead of 2.…”

Résumé. La DBO5 (Demande Biochimique en Oxygène en 5 jours) permet de mesurer la charge en matière organique biodégradable d'un échantillon d'eau. Proposé pour la première fois en 1912 par la Royal Commission for Sewage Disposal en Angleterre, la DBO5 est désormais un paramètre incontournable à l'évaluation des performances d'une station d'épuration et au calcul des redevances pour pollution. Bien que simple d'utilisation, le bas-débit, la durée, le domaine de validité et l'encombrement du matériel rendent l'analyse DBO5 peu opérationnelle. Ainsi, des méthodes alternatives voient progressivement le jour afin de pallier à ces inconvénients. Cette publication présente la validation d'Enverdi-DBO, une solution alternative à la méthode standard, réalisée en microplaque 96-puits et délivrant un résultat en 48h. La technologie repose sur la mesure de la fluorescence d'une sonde redox exprimant l'activité catabolique microbienne. Cette validation se base sur l'analyse, selon la méthode Enverdi-DBO et la méthode standard, de 261 échantillons d'eaux usées et épurées provenant de différentes stations d'épuration urbaines. L'analyse statistique des résultats indique que les valeurs de DBO5 obtenues selon les deux méthodes sont équivalentes.

“…For about 98% of the analysed samples, the Enverdi® DBO result felt in the uncertainty range of the standard methods. This conclusion is consistent with the previous studies carried out with lower sample populations [35,36]. In addition, this equivalence demonstration is based on analysis performed over long time periods (from several months to 1 year), in different locations in France and USA, with sample BOD5 values ranging from 3 to 500 mg O2.L -1 .…”

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.

“…TS were analyzed according the American Public and Health Association Standard methods (APHA et al 1998). BOD 5 was assessed by measurement of microbial catabolic activity using a fluorescent redox indicator in 96well microplates (Envolure, France) (Muller et al 2014). TOC measurements were made using high temperature catalytic oxidation techniques (EN 1484(EN :1997.…”

Pig manure is a complex mixture with excessive nutrients such as ammonium, microbial pathogens and may contain contaminants such as antibiotics. Conventional pig manure management practices caused water contamination. Sludge treatment wetland has been evaluated to determine its potential use under Mediterranean climate aiming at a parsimonious use of water and preventing water contamination, two major steps to preserve water resources in the Mediterranean Basin. Preliminary NH4-N degradation was tested using aeration process and/or addition of commercial bacterial products. Aeration alone appeared to be sufficient to ensure nitrogen transformation of the pig manure at lab small-scale (10 L) and medium-scale (300 L). Selected plant species e.g., Carex hispida for use in the integrated constructed wetland tolerated the nitrogen content after aeration enabling their use in a treatment vertical bed.
