Abstract

Vacuum membrane distillation was investigated as a possible alternative technique for the removal of volatile organic compounds from contaminated water. A mechanism for the trans-membrane removal of benzene was postulated and corroborating experimental evidence is presented. Batch experiments were conducted on dilute benzene-water mixtures using a tubular polypropylene membrane module. The concentration within the feed reservoir was monitored over time and the results analysis was conducted from an overall mass transfer coefficient perspective. The impact of operating variables such as feed concentration, flow rate, temperature and downstream pressure was investigated. A previously published case study was used as a basis for comparing volatile organic compound removal by vacuum membrane distillation to air stripping in a packed tower.
