ne service life, which essentially determines whether thisnew proc- , ess,$ economical or not, was investigated under practical operating conditions. 1 3. Results Filter auxiliaries, such as filter beds and kieselguhr, are necessary in the beverage industry The roductsto be filtered displaya more or less high degreeof turbidityand are difficulttofil- ter & to the high proportion of finely dispersed substances and colloids The trials conducted within the framework of the project sponsored have shown that cross- flow technology is capable of replacing the existing conventional processes in some areas of beverage filtration, thus allowing replacement of kieselguhr as filter auxiliary. The filtered pro- ducts can be classified as very good as regards the degree of clarity and sensory analysts. Within the framework of the project sponsored, it was also possible to show that industrial- scale plants with more than 1 m2 membrane area can be integrated in existing processing operations from the point of view of plant engineering and control technology. However,theresultsalso make itclearthatfurther development stepsare necessaryin orderto increase acceptance on the partofthe user.Thesedevelopments must lead toasmallersystem size, reduction of the circulating volume required, change in the module geometry, an increase in the variability of the modules and an improvement in the specific filtration perform- ance. 1 Low- ss heating systems 1 The burning of fossil fuelsfor producing heat and power represents the main source of anthropogenic emissions. Sulphur dioxide (SO,), nitrogen oxides (NO,) and dust count among the most significant air pollutants in terms of quantity. Furthermore, emission of products created by incomplete combustion, such as soot and harmful organic compounds, also occurs. Froma historical point of view, the mass pollutants initially held centre stage in clean- air policy. Therefore, sponsorship measures geared towards re
