Abstract

In this study is presented some important aspects regarding modern processes of ultrafiltration of waste water, through an organic hollow fibers membrane from polyacrylonitrile. Wastewater produced daily from industries contains a variety of organic and inorganic compounds that harm the environment if they are not removed from the water. In this study, the efficiency of retention of two compounds such as yeast and bentonite will be highlighted, from a solution that mixes these substances. The aim is to monitor the final volume of the permeate, the operating lifecycle of membrane without deteriorating over time, the influence of the operating parameters of the ultrafiltration process, etc. It is very important to investigate the impact that water with polluting compounds can have on the environment if the waste water will be discharged into the natural water resources, without removing these pollutants. The results of the study showed that food yeast mixed with bentonite can have a satisfactory retention rate of over 20% at a transmembrane pressure of 0.8 bars and at a temperature that oscillates around 26-27 ° C.
