THE USE OF POLYMERIC MEMBRANES IN WATER FILTRATION
Abstract
Membrane processes are methods to remove unwanted elements from wastewater stream. Considering this, the water flow is an important parameter to filter waste water and membrane fouling is of great interest in membrane filtration because it reduces wastewater flow passage through the area of the membrane. In order to improve the filtration process, many studies have investigated the use of different concentrations of polymer added in the preparation of polymeric membranes and how much it influences the properties of membranes, like hydrophilicity, permeability and antifouling. One of the most used polymers is polyethersulfone. This paper compares the water flows considering the influence of the polymer concentration, thus, its influence on the properties of membranes used on water filtration.
