| Description
| - Volatile organic compounds are transported amongst various constituents of environment and are dreaded contaminants of underground waters due to their tendency to remain in these waters and to migrate with them and thus to interfere with the sources of underground water used to drinking purposes. Moreover, volatile organic compounds negatively influence human health. Various techniques of VOCs decontamination from water are available. These technologies are mostly based on the adsorption or absorption of contaminant by means of suitable sorbent or on the disposal of VOCs by their transfer into the air in stripping columns (aeration). However, while these technologies are effective for large-volume treatment of water, they are not so suitable for smaller and/or individual water sources (wells) that can be contaminated as well. Membrane processes shape up as perspective for small water sources. Water either passes through membrane (reversed osmosis, nanofiltration etc.), or the membrane serves for the separation of two different phases, i.e. treated water and gaseous phase, into which the contaminant passes. The last of the above mentioned techniques requires such membranes that have low water permeability and high VOCs permeability. A series of tests was performed assessing organic polymer membranes from this aspect. Toluene was used as a model VOC and its vapors permeability was compared to water vapors permeability by gravimetric measurements. Various materials (PE, PVC, PUR, PTFE, silicone, rubber) were studied in order to find those having the lowest water permeability and the highest toluene (VOC) permeability. Silicon rubber can be considered promising for further research.
