The BM Respirometry is a technology designed by SURCIS that combines the traditional Respirometry with a state of the art method that permits to carry out different types of tests on a fast and simple way to measure the oxygen uptake and derived parameters from the microorganisms of the activated sludge in any biological wastewater treatment plant. The key points ...
Wastewater characterization is nowadays considered an indispensable step that provides all the necessary information for a reliable management and design of biological treatment processes. This characterization should mainly include the chemical oxygen demand (COD) fractionation as an indispensable tool for all that. COD fractionation involves identification of non-biodegradable and ...
Introduction Respirometry is the measurement and interpretation of the biological oxygen consumption rate under well defined experimental conditions. Because oxygen consumption is directly associated with both biomass growth and substrate removal, respirometry is a very useful technique for monitoring, modeling and control of the activated sludge process The ...
In fact, this same toxic effect can be translated to the bCOD/DQO (Biodegradable COD / COD) where, by varying the ratio [sample volume/ sludge volume] in the respirometry tests, there is the possibility to generate different levels of apparent biodegradability degrees, when the reality is that the relatively low values of DQOb are the consequence of a certain degree of toxicity ...
In a single batch reactor, the measuring system can work as LSS and LFS batch respirometry. The system is optimized by a one-sense membrane device, that together with a dividing plate, is able to isolate the measuring chamber and avoid bubbles against the DO sensor. OUR This mode is making use of the LSS respirometry type. The ...
The main objective of this study is to demonstrate the importance of mixing conditions as a source of inconsistencies between half-saturation indices in comparable systems (e.g. conventional activated sludge, membrane bioreactor) when operated at different conditions or different scales. As proof-of-principle, an exemplary system consisting of the second vessel of a hybrid respirometer has ...
The well known critical influence of those factors on the nitrification are here analyzed by making use of a specific software and advanced respirometry based on a dynamic LFS system, where the test conditions can be set in the corresponding test-settings board and their levels modified throughout the test performance. ...

The present paper describes a relatively simple, fast procedure whereby the use of an advanced and high sensitivity respirometry system, both parameters are obtained throughout a novel method to accurately determine values of the half-saturation DO constant (KOA) and active nitrifier concentration (XA) from the results of a single respirometry ...
What is BM Respirometry? It is a technology in where facets of the traditional and techniques from the most advanced respirometry are gathered in one state of the art analyzer of exclusive Surcis company design. The BM system under a powerful software permits calculations of decisive parameters approached to design, control and protect the ...
The objective of the study was, therefore, to obtain a clear confirmation on the toxic and biodegradable nature of a genuine sample from Celanese Iberian Chemicals with the purpose of contributing with fundamental data to the future activated sludge process design. Respirometry system This service was carried out by specialized SURCIS (Spain) personnel by means ...
Introduction The use of the BM advanced respirometry system enables the user to get the precise calculation of the operating parameters and limit set points that any activated sludge actually needs within the framework of an energy optimization. For that reason, the proper use of this respirometry is more than justified; and not only because of ...

Those current conditions lead to think that they are the responsible of the lack of nitrification; but, in order to get strong arguments of confirmation, the company responsible of the plant management and maintenance wanted to get a respirometry study to analyze and assess the influence of the nitrification activity for the actual winter conditions and be compared with higher ...
The hardware and software of the titrimeter and the respirometer were integrated to construct a novel system of respirometry–titrimetry. The system was applied to monitor a batch nitrification process. ...
Bacteria in the anaerobic degradation process convert the substrate to the final products methane and carbon dioxide. Toxic substances can change the process substantially. The purpose of this study was to investigate the influence of toxic cyanide on biogas production in anaerobic degradation of glucose at 40°C. The OxiTop respirometric system offers a quick and simple method for measurement of ...
