The Use of Polymer Membranes to Counteract the Risk of Environmental of Soil and Water Contamination

Abstract

Chemical, biological, radiological, or nuclear (CBRN) contamination of the environment is a significant threat to human health and life as well as environmental safety. It is then necessary to take actions aimed at minimizing and eliminating the threat. Depending on the type of contamination, various methods are used, including sorption, biodegradation, separation, or ion exchange processes in which membranes play an important role. The type of membrane is selected in respect of both the environment and the type of neutralized pollutants. Therefore, the production and modification of membranes are being adapted to the type of contamination and the purpose of the work. This article presents examples of membranes and their possible applications depending on the part of the environment subject to reclamation and the type of contamination.

Analysis of the Water/Cement/Bentonite Ratio Used for Construction of Cut-Off Walls

“…There are several different materials and mixtures of materials that can be used to create these barriers [2,3]. Geomembranes made of materials such as polyethylene, PVC, or EPDM are excellent barriers against the seepage of contaminants into groundwater [4,5]. They can be used alone or as part of comprehensive environmental protection systems.…”
