The main regularities of water purification from Ca2 + by microfiltration ceramic membranes, in particular the influence of working pressure, duration of experiments, concentration of Ca2 + ions in the initial solution on reducing the content of these ions in the filtrate were investigated. As a result of experiments, ceramic membrane isolating characteristics: Ca2+ ion retention factor R (%) and specific productivity Jv (m3/(m2/h) of the membrane were calculated. Processes of water purification from Ca2 + ions were carried out at a pressure of 0.7 MPa. It was found that calcium ion retention factor has increased from 60 to 65.5% with increasing the number of modifications from one to four. Herewith, membrane specific productivity at the end of each modification has not almost changed. Reducing the membrane specific productivity is associated with decreasing the solution density, which is the result of lowering the СаСІ2 solution temperature and raising the thickness of the dynamic membrane, formed during modification.
Theoretical and numerical processing of selectivity values, which were obtained in the course of modification, was performed. For processing the experimental results, taking into account the probability of their obtaining and experimental error, statistical methods were applied. It was concluded that the studies prove the highest efficiency of the fourth modification of the membrane since it is not covered by the determined interval. Further membrane modification is not expedient because the productivity will decrease, which will limit its use on an industrial scale.References
