Removal of Triethylamine Vapor from Waste Gases by Biotrickling Filter
Sampling of triethylamine in the cold-box unit in an auto-manufacturing company in Iran has indicated the average concentration of 430 mg/m3 in the emission duct. In this study a biotrickling filter was used for treatment of triethylamine in air stream. Triethylamine removal efficiency (K/L) pattern was evaluated by changing volumetric loading (L), superficial gas velocity (Uo), empty bed gas r...
متن کاملAdsorptive Removal of Chromium (VI) from Aqueous Solutions by using Sugar and Distillery Waste Material
Raw bagasse, Bagasse fly ash and distillery sludge, the waste generated in sugar mills and distillery have been used as lowcost potential biosorbent for the removal of hexavalent chromium from an aqueous solution. The effect of hydrogen ion concentration, contact time, adsorbent dose, initial concentrations of adsorbate and adsorbent dose on the uptake of chromium were studied in batch experime...
متن کاملAdsorptive Removal of Toxic Chromium from Waste-Water Using Wheat Straw and Eupatorium adenophorum
Environmental pollution with heavy metals is a serious issue worldwide posing threats to humans, animals and plants and to the stability of overall ecosystem. Chromium (Cr) is one of most hazardous heavy metals with a high carcinogenic and recalcitrant nature. Aim of the present study was to select low-cost biosorbent using wheat straw and Eupatorium adenophorum through simple carbonization pro...
متن کاملApplication of an adsorptive-thermocatalytic process for BTX removal from polluted air flow
BACKGROUND Zero valent iron and copper oxide nanoparticles (30-60 nm) were coated on a bed of natural zeolite (Clinoptilolite) with 1-2 mm grains and arranged as a dual filter in a stainless steel cylindrical reactor (I.D 4.5 cm and L = 30 cm) to investigating the coated bed removal efficiency for BTX. The experiments were conducted in three steps. First, with an air flow of 1.5 L/min and tempe...
متن کاملTwo-stage biofilter for effective NH3 removal from waste gases containing high concentrations of H2S.
A high H2S concentration inhibits nitrification when H2S and NH3 are simultaneously treated in a single biofilter. To improve NH3 removal from waste gases containing concentrated H2S, a two-stage biofilter was designed to solve the problem. In this study, the first biofilter, inoculated with Thiobacillus thioparus, was intended mainly to remove H2S and to reduce the effect of H2S concentration ...
