Influence of Ionic Strength and pH of Dispersed Systems on Microfiltration
Original language description
The influence of particle shape, zeta-potential and size with change of pH and ionic strength on permeate flux during the microfiltration of model dispersions (two different china clays with mean particle sizes 3.5 micrometers and 1.5 micrometers) on flat sheet ceramic membranes (ZrO2, mean size of pores 0.2 micrometers) have been studied. The experiments include measurement of the basic characteristics of model dispersions. The description of the experimental system is also presented. The results of the experiments show that zeta-potential of particles have indispensable impact on the permeate flux. This phenomenon is especially pronounced during the microfiltration of dispersion in the area close of isoelectric point of dispersion, when the value ofpermeate flux increased to double value of non-treated dispersion. This phenomenon has caused the particle interaction. In area closed of isoelectric point the dispersion had tendency to instability, particles tend to aggregate. It result
