The treatment of winery wastewater was performed at full-scale applying a two-stage fixed bed biofilm reactor (FBBR) system for the discharge in the sewerage. The results of the first year of operation at the full-scale plant are presented. Values of removed organic loads and effluent concentrations were interpreted on the basis of the COD fractionation of influent wastewater assessed through r...

The result of simulation of an idealized thin wet film connecting fixed points in the Euclidean plane is a length-minimizing curve. Gradually increasing the exterior pressure we are able to achieve the film configuration near to the Steiner minimal tree. This film evolution may be an interesting tool for solving the Euclidean Steiner problem, but several dead-point situations may occur for a ce...

Today, a variety of processes is available for the production of two-dimensional and three-dimensional microstructured polymer components. The current state of the art, however, meets with considerable problems in particular when fabricating microporous cavities that are required for e.g. 3dimensional cell cultures (Fig. 1). With a few exceptions, such as the fabrication of so-called microporou...

This paper considers what decolonizing film education might mean through a series of research initiatives undertaken across different cultures which explore social media platforms for creating moving image sequences. The attends to three factors in the current climate education: accessibility medium, its immediacy dissemination, and democratizing effect that these conditions have had on medium ...

Excess sludge production is one of the limitations biological activated process. Therefore, study’s objective to upgrade MBBR process an integrated fixed film-activated (IFAS) reduce excess production. Two scenarios were followed in this study eliminate process: first, modifying moving bed biofilm reactor (MBBR) system by increasing solid retention time (SRT) from 5 15 days; and second, upgradi...
