Energieeffizienzsteigerung in der Prozesswasseraufbereitung - Untersuchungen zu Bildungsmechanismen von SilikatbelagenEnergy Efficiency Increase in Process Water Treatment - Investigations into Formation Mechanisms of Silica Fouling
Investigations on the formation mechanisms of silicate films on reverse osmosis membranes and their morphological characteristics are presented. Relevant influencing factors on the formation of coatings are considered and the individual mechanisms are described. Furthermore, the essential characterization characteristics for the investigation of silicate coatings are determined, the applied analysis methods are described and an overview of the sample preparation is given.
