Fixed-bed adsorption column design
WebThe values of column parameters were predicted as a function of flow rate (5-15 ml/min), bed depth (5-15 cm), particle size (1-2 mm) and inlet metal ion concentration (100 mg/l). Webadsorbent and there is no dispersion or bypassing in the column. Also, the change in volumetric flow rate along the column due to expansion and adsorption or desorption is neglected. The calculations with these assumptions are only the first step in design calculations. Calculations to include non-equilibrium and dispersion effects are deferred.

WebDec 6, 2024 · Another novelty of this work is that bentonite-activated carbon-based adsorbent was used in a fixed bed column for the first time. In currently available data from the literature, there are two types of similar studies. The first presents the removal of micropollutants in a fixed bed column packed with conventional materials [18,29,30]. WebQuestion: 2. A water containing a contaminant TOC of 200 mg/L (02 g/L) is treated by a fixed-bed carbon adsorption column. The design flow rate of the plant is 150,000 L/day. The allowable concentration in the effluent is 10 mg/L of TOC. An experimental column is designed to establish a breakthrough curve for the carbon adsorption.
