An integrated system for wastewater COD characterization and a case study
The guidelines of Activated Sludge Model (ASM) can make the use of modeling more straightforward and systematical. Therefore, this paper aims to develop a guideline for wastewater COD characterization. Four physical-chemical methods were compared experimentally for wastewater characterization in this paper and flocculation + 0.45 μm membrane filtration combining respirometry was selected to ...

Wastewater characterisation and performance upgrading of a domestic wastewater treatment plant: the Erzincan case
A detailed characterisation of the incoming wastewater and a performance evaluation were carried out for the domestic wastewater treatment plant of Erzincan City. Conventional characterisation results showed that Erzincan has a medium strength wastewater quality. Structural characterisation of the chemical oxygen demand (COD) indicated that the biodegradable fraction of the total COD was 64.7%. ...

Advanced respirometry for activated sludge process
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 Respirometry technology is a well ...

Using respirometry for energy optimization in a nitrifying biological wastewater treatment system
ABSTRACT Many wastewater treatment plants use more than 50% of their total energy budget in the aeration basin and, when nutrient removal is included in the activated sludge process, it is very common that the majority of oxygen uptake goes to the nitrification process. For that reason, in most wastewater treatment plants, energy optimization is focused on nitrification management. This ...

BM-T respirometry study about the adaptation of a potential toxic industrial wastewater to an specific activated sludge case study
Enterprise: CELANESE CHEMICALS IBÉRICA, S.A. (Tarragona – Spain) Premier materials for painting industry Celanese enterprise, before the SURCIS study, in several laboratories had already tried several analysis of its industrial wastewater in order to find out if it could be certain degree of toxicity when wastewater will be treated with activated sludge and also to know its ...

BM Respirometry benefits for activated sludge process management, research and training
A biological process controlled by non-biological measurements? All treatment plant efficiencies are geared to the waste that they receive. The microorganisms found in the waste need food and oxygen to survive, the food is provided as soluble organic carbon in the waste stream and the oxygen is obtained through the aeration process in the treatment plant. Once a treatment plant has been built, ...
