Recent advances in VOCs removal from water by pervaporation.
Pervaporation (PV) is a separation process in which minor components of a liquid mixture are preferentially transported by partial vaporization through a non-porous permselective (selectively permeable) membrane. PV is an emerging technology in environment cleanup operations, especially in the removal of volatile organic compounds (VOCs) from industrial wastewaters or contaminated groundwaters....
متن کاملInfluences of Permeate Pressure and Feed Flow Rate on Benzene Removal from Gasoline by Pervaporation
In this work, the effects of permeate pressure and feed flow rate on the performance of a composite polyvinyl alcohol (PVA) membrane in the removal of benzene from gasoline by pervaporation (PV) were evaluated. The results indicate the remarkable effect of permeate pressure on membrane performance as reducing permeate pressure (higher vacuum) from 30 to 3 mmHg causes the total flux to increase ...
متن کاملRemoval of trace metal contaminants from potable water by electrocoagulation
This study investigated the effects of four operational and environmental variables on the removal of trace metal contaminants from drinking water by electrocoagulation (EC). Removal efficiencies for five metals (arsenic, cadmium, chromium, lead and nickel) were compared under varying combinations of electrode material, post-treatment, water composition and pH. Iron electrodes out-performed alu...
متن کاملRemoval of VOCs from Contaminated Groundwater and Soils by Pervaporation LEAD AGENCY: Environmental Protection Agency
PROBLEM STATEMENT: Petroleum hydrocarbons, and other volatile organic compounds (VOCs), which are found to contaminate groundwater and soils, are usually treated by pump-and-treat methods, which are very time-consuming, expensive, and not very effective. We are proposing the use of pervaporation for effectively removing these hydrocarbons and VOCs from contaminated soil and groundwater (with or...
متن کاملRemoval of methyl tert-butyl ether from water by pervaporation using ceramic-supported polymer membranes
Pervaporation removal of methyl tert-butyl ether (MTBE) from dilute aqueous solutions was demonstrated using ceramic-supported polymer (CSP) membranes. These membranes were created by the free radical graft polymerization of vinyl acetate onto a vinyl trimethoxysilaneactivated porous silica substrate having a native average pore size of 500 Å. The resulting membranes consisted of poly(vinyl ace...
