摘要:

AbstractNon‐Biological Removal of Organic Pollutants from Water. Contaminants present in waste water, seepage water and ground water include salts, heavy metals and organic compounds of low biodegradability. This paper considers the wide range of physico‐chemical processes available for separation of such compounds from water and points out their optimal and economic range of application. Main subjects are desorption processes (air/steam stripping), adsorption processes (activated carbon, polymeric resins) and membrane separation processes. Alternative water treatment technologies (evaporation, distillation, liquid‐liquid‐extraction, oxidation, flocculation and precipitation) and combined processes are presented and di

摘要:

AbstractCleaning of Exhaust Air and Solvent Recovery by Adsorption on Polymer Resins. In an overview the technologies of air cleaning and solvent recovery is followed by an account of the adsorption of solvents on polymer resins. Test plant, experimental adsorption equilibria and breakthrough curves as well as mathematical modelling for the design of fixed bed adsorbers are the main focus of attention. Practical examples demonstrate the advantages of using polymer resins in solvent recovery.

摘要:

AbstractFlowability of Bulk Solids – Definition and Measuring Principles. The flowability of bulk solids has to be known for many practical applications. The present paper describes how the flowability is defined and on which physical properties it depends. Experimental determination of the flowability using a shear test is demonstrated. Conditions influencing measuremed results are described. Finally an overview of various methods used for characterization of the flowability of bulk solids is give

摘要:

AbstractApplication of Enzymes and Antibodies in Organic Solvents. This review outlines the influence of organic solvents on antibodies, enzymes and their reactions, the different kinds of enzyme‐solvent systems, the various advantages of organic solvents compared with water and how they can be used for synthetic and analytical purposes. Main applications are the enzymatic synthesis of optically pure organic chemicals used as drugs, research chemicals, dyes or fragrants, as well as the analysis of hydrophobic compounds. Examples can be given of bioconversions in organic media by microbial cells and of syntheses with catalytic antibodies. Moreover, the full biotechnological potential of chemically or genetically engineered enzymes can only be exploited if the diversity of possible media is taken into accoun
