    Combined Membrane Process at Waste Water Treatment

  • Original language description

    This contribution deals with the study of hollow fiber membrane dead-end microfiltration combined with powdered activated carbon sorption used in removing of organic dyes from wastewater. Adsorption characteristics of model reactive dye OSTAZIN RED on powdered activated carbon were studied. Adsorption isotherms and rate constant were determined from which followed, that adsorption of this dye on activated carbon is favorable, however the time to reach an equilibrium is around 7 days. From hybrid separation process characteristics measurements resulted that the activated carbon does not foul this type of membrane and the permeate flux is recovered after membrane backflush. A simple mathematical model describing dynamic sorptive process in microfiltration system is presented and discussed.

    Úprava odpadních vod pomocí kombinovaného membránového procesu

  • Czech description

    Příspěvek se zabývá studiem mikrofiltrace s dutými vlákny kombinované se sorpcí organického barviva na aktivním uhlí. Byly stanoveny sorpční charakteristiky použitého barviva (Ostazin red). Z naměřených charakteristik separačního procesu vyplynulo, že aktivní uhlí nezanáší nevratně membránu a zpětný proplach je vysoce účinný při obnově intenzity toku permeátu.Dále byl navržen jednoduchý matematický model popisující chování procesu sorpce jako součásti mikrofiltračního systému.
