To date, the application of various physicochemical and biological abatement methods such as sealing open tanks (Cheng et al. ), air stripping (Fang and Khor ), steam stripping (Ortiz-Del. velocity, liquid properties, operating conditions, column dimensions, gas distributor design, solid type and concen-trations are presented. Design and scale-up The design and scale-up of bubble columns have gained considerable attention in recent years due to complex hydrodynamics and its influence on transport Size: KB. Obviously air stripping by itself is not a solution since the pollution is only transferred from one phase to another. Treatment of the VOC laden air that leaves an air stripper is necessary and several alternatives will be discussed later. VOC removals in excess of % are possible with air stripping when a packed column is used. PackedFile Size: KB.

Design of fixed bed adsorption columns Fixed bed is a widely used method for adsorption of solutes from liquid or gases. Granular particles are packed inside the fixed-bed. The fluid to be treated is passed down through the packed bed at a constant flow rate. Mass transfer resistances are important in the fixed bed process and the processFile Size: KB.

A column with a high N will have a narrower peak at a given retention time than a column with a lower N number. Efficiency (N) Column efficiency is used to compare the performance of different columns. It is probably the most frequently cited parameter of column performance and is expressed as the theoretical plate number, N. Efficiency N = Air Stripping in Industrial Waste Water Treatment Texas. pp. [This book provides d etailed design and simulation of the dynamic behavior of the air stripping process in a packed. The material balance for solute A can be applied to any part of the column. For example, the material balance for the top part of the column is YA t, = L V A t, X + A A LX Y V − () In this equation, XA and YA are the mole ratios of A in the liquid and vapor phase, respectively, at any location in the column including at the two terminals.
