Evaluation of Vermifilter Efficiency in Petroleum Wastewater Treatment (BTEX), M.Sc. Thesis Sharif University of Technology ; Torkian, Ayub (Supervisor) ; Mirzai, Mohammad (Supervisor)
Abstract
The aim of this thesis was to find the optimum retention time for treatment of synthetic petroleum wastewater by a wastewater treatment system made with a bucket, mineral material and earthworms residing in a vermibed. In order to make the desired flow happen, height difference was utilized. The polluting substance used for making wastewater was BTEX. As the wastewater was synthetic, the concentration was also a variable. The ultimate soluble concentration was 3200 mg/l and more concentrations were not tested. Parameters such as number of worms, worm’s growth rate and their distribution pattern, humidity amount and distribution and worm’s acclimatization time during organic loading shock...
