Biofiltrtion of VOCs in an Effluent Gas from Zeolite Rotor Concentrator

Ching-Yi Wu and Ming-Shean Chou
Abstract—In this study, a biotrickling filter (BF) packed with 32 to 64 liters of wood chips with average sizes 2.03cm×2.25cm, wet packing density 470 kg/m3, void fraction 0.57, and specific surface area 300 m2/m3 was tested for the removal of < 10 ppm THC (total hydrocarbon, expressed as methane equivalent) in gases vented from a field zeolite rotary concentrator for waste gas treatment in a TFT-LCD manufacturing plant. Results indicate that with operation parameters of EBRT (empty bed retention time) 2.0 s, pH 6.5-8.0, and daily nutrition milk 0.11 L/m3 chips (10 g milk powder/m3 chips), 50% THC in the influent gas could be removed. It was estimated that around 0.016 USD is required for treating 1000 m3 of the vented gas from concentrators with a gas flow of 2,000 Nm3/min.

Index Terms—Biotrickling filter, volatile organic compounds, TFT-LCD.
