Organizacija majhnega podjetja
Žiga Terdič, 2006

Opis: Majhna podjetja pridobivajo vse bolj pomembno vlogo v gospodarstvu. V primerjavi z velikimi podjetji se lažje prilagajajo razmeram na trgu. Ključi uspešnosti in konkurenčnosti majhnih podjetij na trgu so dobro oblikovana vizija, politika podjetja, struktura organiziranosti ter oblikovanja in izvajanja poslovnih funkcij. Primerjava majhnih podjetij s svojo konkurenco omogoča nenehno izboljševanje. Običajno se podjetja primerjajo z metodo benchmarking. Podobno kot v velikih podjetjih, se tudi v majhnih podjetjih prepletajo vloge podjetnika, managerja in navsezadnje tudi ključnega lastnika.

Efficient mineralization of aqueous organic pollutants by photocatalytic ozonation
Marko Kete, Urška Lavrenčič Štangar, 0

Opis: Photocatalytic ozonation process using TiO2 photocatalyst (O3/TiO2/UV – PH-OZ) conducted in acidic water environment often leads to synergistic effect in terms of decomposition and mineralization of aqueous organic contaminants, which makes the process suitable for waste water treatment or pretreatment of drinking water. [1,2] The synergism is among other factors (pH, O3 dose, T,…) greatly influenced by photocatalyst physicochemical properties and pollutant type. In the first part of the study, five different commercial TiO2 photocatalysts (P25, PC500, PC100, PC10 and JRC-TiO-6) were used in O2/TiO2/UV, O3/TiO2 and O3/TiO2/UV advanced oxidation systems for degradation of two pollutants (dichloroacetic acid - DCAA and thiacloprid – neonicotinoid pesticide), simultaneously present in water solution. [3] Results of PH-OZ (O3/TiO2/UV) experiments showed that in contrast to DCAA which adsorbs on TiO2 surface, synergistic effect is much more expressed in the case of thiacloprid which doesn’t adsorb. The influence of BET surface area of the photocatalyst and its dispersivity will be discussed. In the second part of this study, selected catalysts were immobilized on a proper support to avoid post-filtration step in the process of greywater treatment. A good adhesion of a catalyst on various supports was successfully achieved by immobilization of commercial TiO2 powders (P25, P90, PC500) with the help of a sol-gel silica-titania binder [4]. For the purpose of simulated greywater treatment, special compact reactor was designed and developed, utilizing Al2O3 porous reticulated monolith foams as TiO2 carriers and UVA-lamps inside (Fig. 1). [5] With degradation of LAS+PBIS and Reactive blue 19 (RB 19) as representatives of surfactants and textile dyes respectively, commonly found in household greywater, and phenol as trace contaminant, an evaluation of PH-OZ and photocatalytic oxidation has been performed (an example in Fig. 2). Synergistic effect of PH-OZ was generally much more expressed in mineralization reactions, showing TOC half lives of less than one hour for the mixture of pollutants in compact reactor. [5] Due to its superior cleaning capacity, PH-OZ process employing efficient photocatalysts is suitable for treating wastewaters also with higher loading of organic pollutants. 1. U.
