“…This technique, based on the determination of the heat released by the bacterial culture during substrate degradation, has proven to be very useful for biokinetic characterization of microbial biomass as well as for identification of biological events such as shifts from one substrate to another or limiting effects [5]. Thermograms (Fig.…”

“…The Bio-RC1 is a standard 2 L jacketed glass calorimeter with a sensitivity of5-10 mW L-l [5]. In the isothermal mode, a low-viscosity silicone oil is pumped at a high rate (2 L s -l) through the reactor jacket in order to maintain a constant temperature of the reactant medium (Tr) by proper control of the jacket temperature (Tj).…”

“…The default ASM2d yield coefficient of 0.013 mJ/gO2 is used for COD oxidation and a literature value of 0.0059 mJ/gO2 from Daverio (2003) is used for ammonia oxidation. The heat load is completed with the addition of solar radiation and power input from mixing and pumping.…”

The HPO Solver software tool combines biological, engineering and cost models used in wastewater treatment to assist the user in making design and economic decisions. A unique feature of this steady-state tool is a model that calculates biological heat, an important design consideration when treating high strength waste. Three industrial case studies are presented : a leachate plant, a pharmaceutical plant and a tank washing facility producing chemical waste. Results of the biological heat model are presented as well as output of the cost model which has the capability to provide rough estimates of capital and operating costs for refrigeration. In the case of the leachate plant, the model predicts underestimated capital costs of 11% and operating costs of 6% when neglecting biological heat.

The present study compares two experimental methods to evaluate Anammox activity based on the assessment of (1) the N(2) production rate by a manometric device, as previously proposed, and (2) the heat production rate by a microcalorimeter. Two samples of Anammox suspended biomass were taken from a pilot-plant, and their specific Anammox activity measured by both techniques. Both methods were successfully applied. As for calorimetric tests, they were performed for the first time on Anammox enriched sludge samples. Comparisons between the specific Anammox activities estimated by manometry and calorimetry and between expected (from the reaction enthalpy) and measured heat productions were performed. Promising results were obtained.
