Wastewater treatment

Nanofiltration (NF) membrane technology has made rapid progress and then extended its application fields. It has obtained in particular the good results in the removal of organic and inorganic matters or microbes in the water and wastewater. To investigate the applicability and characteristics of NF

The filterability of activated sludge is an important factor for the economical operation of membrane bioreactors (MBR). In the literature mainly investigations on sludge dewaterability in respect to further disposal are published. In this study, a procedure for determining filterability in a crossf

In the run of the last decades the coming up of new technologies as well as new needs has increased the interest in wastewater treatment. This study concerns the synthetic membrane development; synthesis of polymers for membrane preparation and the extraction of volatile organic components in aqueou

An intermittently aerated membrane bioreactor using a submerged hollow fiber membrane was applied in laboratory scale to treat household wastewater including toilet flushing water. Nitrogen removal was optimized with intermittent aeration of the reactor and adjusting the time lengths of anoxic and a

W ith short term batch experiments, EPS cont ent and filterability o f activated sludge can be m anipulated. Changes in filterability can be m easured accurately with the filtration characteris ation unit. With the addition o f a simple carbon s ource the filterability o f the activated sludge deter

T he presented study demonstrates that the outlined modelling concept for membrane bioreactors could successfully be applied to describe the system behaviour of a pilot-scale wastewater t r e a t m e n t plant, e q u i p p e d with m e m b r a n e f iltration units. In particular, the model describi
