Effects of the surface-active agents on the water penetration of the ultrafiltration membranes

New thermal resistant polimer and metallic-ceramic membranes have been created for operation of the membrane technique that makes it easier to choose chemical agents and high temperature regimes for cleaning. In the article data about impacts of the sanitarian cleaning regimes of the ultrafiltration plants on the indices of the sanitarian and hygienic state are given. The study of compatability of the nine types of the surface active substances with the structure of the membranes of the UF-module, their moistening, emulsifying and foam formation properties was carried out in order to determine rational concentration of the surface active agents in the cleaning agent for regeneration of the membrane plants. The results of the study demonstrated that concentrations of the five surface-active agents for good emulsifying of the mixtures of vegetable oils and milk fat (1:1) should be in the range 1,5-2,5 %.
