Abstract: A method is proposed to predict fixed‐bed adsorber removal of individual organic compounds and surrogate parameters such as total organic halogen (TOX or TOC) in the presence of an unknown adsorbing mixture by representing ...

Abstract: Fixed‐bed absorber dynamics have been predicted successfully using the homogeneous surface diffusion model (HSDM) for over 100 adsorbate‐adsorbent systems which include a number of the organics found in drinking water and ...

Abstract: Fixed‐bed adsorber dynamics have been predicted successfully using the homogeneous surface diffusion model (HSDM) for over 100 adsorbate‐adsorbent systems which include a number of the possibly harmful organics that may ...

Abstract: A treatment strategy is examined whereby organic compounds in the aqueous phase are first removed by fixed-bed adsorption, followed by off-line regeneration of spent adsorbent using saturated steam (160°C) and cleanup of ...

Abstract: Because the presence of hydrogen sulfide

Abstract: Several thermodynamic models that may be used to predict single and binary adsorption equilibria for organic vapors and competitive interactions between water vapor and a single organic vapor were developed and tested. The ...

Abstract: The overall objective of this study is to investigate the technical feasibility of removal and destruction of organic contaminants in water using adsorption and photocatalytic oxidation. The process consists of two consecutive ...

Abstract: Heterogeneous advanced oxidation involves the use of photoactive metal oxide catalysts illuminated with near‐UV light to generate highly reactive species that can oxidize organic chemicals. This study examined the technical ...

Abstract: A rapid small‐scale column test (RSSCT) that uses a smaller adsorbent particle is used to simulate a five‐month pilot plant adsorption study in several days. The RSSCT is a small‐scale physical model of a full‐scale fixed‐bed ...

Abstract: An equilibrium column model (ECM) was developed to evaluate multicomponent competition in fixed‐bed adsorption columns. The model ignores mass transfer resistances and uses ideal adsorbed solution theory to predict the ...
