BTEX removal by PV on polymeric membranes
Toluene is one of the volatile organic compounds (VOCs) that cause serious damage to human and animal due to their toxicity (Satyanarayana et al. 2004). The other chemicals in this category include benzene, xylenes, ethylbenzene, etc. They are collectively called as BTEX, a word composed of their initial letters. Elimination of BTEX from water, therefore, is a mandatory nowadays.
These chemicals can move freely in water and air; their sequestration is relatively difficult. Air stripping and activated carbon adsorption processes are the conventional methods for removal of BTEX from water. In recent years, a new focus for separation of BTEX from wastewaters is pervaporation. Pervaporation is a membrane process that performs molecular-scale liquid/liquid separation. It is carried out by maintaining the downstream pressure lower than the saturation pressure of the liquid at that temperature. A vacuum or gas flow is used at the permeate...
