Combined ultrafiltration-adsorption water purification of the cationic violet dye

The article investigated the impact of the VMK-1 activated carbon, produced from apricot stones in their pyrolysis in the flow of water steam, on the transmembrane stream and the retention of capacity of the UPM-50 ultrafiltration membrane with respect to the cationic violet dye. It has been shown that the combination of adsorption and ultrafiltration with the process in one unit makes it possible to substantially raise the degree of water purification of the dye concurrently with an increase of the process capacity of purification and prolongation of the membrane service life.
