Produktinformationen "A model to determine oxygen mass transfer coefficient in bioreactors"

The objective of this paper is to present an experimentally validated mechanistic model to predict the oxygen transfer rate coefficient (Kla) in aeration tanks for different water temperatures. Using experimental data created by Hunter and Vogelaar, the formula precisely reproduces experimental results for the standardized Kla at 20 0C, comparatively better than the current model used by ASCE 2-06 based on the equation Kla20 = Kla. (¿)(20-T) where T is in 0C. Currently, reported values for ¿ range from 1.008 to 1.047. Because it is a geometric function, large error can result if an incorrect value of ¿ is used. Establishment of such value for an aeration system can only be made by means of series of full scale testing over a range of temperatures required. The new model predicts oxygen transfer coefficients to within 1% error compared to observed measurements. This is a breakthrough since the correct prediction of the volumetric mass transfer coefficient (Kla) is a crucial step in the design, operation and scale up of bioreactors including wastewater treatment plant aeration tanks, and the equation developed allows doing so without resorting to multiple full scale testings.

EU Gewährleistungssiegel

Die EU führt ein verpflichtendes, einheitliches EU-Label zur Information über die gesetzliche Gewährleistung ein, ergänzt durch ein Garantielabel, sofern eine freiwillige Herstellergarantie besteht.

Ziel der neuen Regelung ist es, Verbraucherrechte transparenter darzustellen und europaweit einheitliche Informationsstandards zu schaffen. Verbraucher sollen auf einen Blick erkennen können, welche gesetzlichen Mindeststandards gelten, unabhängig davon, in welchem Land oder bei welchem Händler sie einkaufen.

EU Warranty Label

The European Union is introducing a mandatory, standardized EU label to provide information about consumers’ statutory warranty rights. This will be complemented by a guarantee label where a voluntary manufacturer’s guarantee is offered.

The purpose of this new regulation is to make consumer rights more transparent and to establish consistent information standards across the European Union. Consumers should be able to see at a glance which statutory minimum protections apply, regardless of the country or retailer from which they make a purchase.
