No full textFull Scale ANANOX® System Performance
No full textThis paper reports the results of the first experimental investigations carried out on the only existing full-scale plant that makes use of the biological treatment system known as ANANOX(R). This system was first set up by the Italian research staff at ENEA (Agency for New Technologies, Energy and Environment) and consists of two biological stages in series: a two-section ABR and an anoxic section followed by an activated sludge process. The investigation aimed primarily to assess system performance under uncontrolled load conditions. In particular, system efficiency was assessed with regard to carbonaceous and nitrogen compounds in the anaerobic and anoxic phases, and the role of sulphides in the denitrification process was examined
Factors affecting washout in intermittently feed upflow anaerobic reactors: experimetal tests and modelling
No full textThis paper reports the results of experimental investigations carried out on a full‐scale ABR and on a pilot UASB to determine biomass washout for various intermittent feed conditions. Particularly, the tests aimed to determine the extent to which sludge washout is affected by such factors as: daily flow distribution; upflow velocity; concentration and sedimentation properties of the biomass. Moreover, in order to obtain a tool to estimate sludge washout in different influent flow conditions, a simulation model of the sludge transport phenomena in the upflow anaerobic reactors is proposed. The results showed that when the influent flow is interrupted for long periods (above 1 hour), once it is resumed considerable losses of biomass into the effluent were found, independent of the upflow velocity. In contrast, with shorter periods, regular sludge expansion took place even with very high upflow velocities (up to 4 m h−1), giving rise to limited sludge washout and high removal efficiencie
Il procedimento di oblazione
No full textSul confine accidentato fra diritto penale e processo, l'oblazione opera producendo effetti attraverso l'accertamento giudiziale. L'oblazione costituisce una fattispecie e, a un tempo, uno specifico modulo procedimentale. Inoltre, nell'oblazione l'accertamento giudiziale ha per oggetto una causa di estinzione del reato cui il procedimento stesso dà vita. Il rito speciale di oblazione persegue l'obiettivo costituzionale della ragionevole durata, garantendo al contempo il diritto di difesa dell'imputato. Tramite un "negozio processuale" l'imputato guadagna benefici, primo fra tutti uno "sconto" rispetto alla pena pecuniaria applicabile, chiedendo una pronuncia di proscioglimento, invece che una decisione equiparata alla condanna. Nel presente scritto vengono affrontate alcune problematiche poste dalla prassi giudiziaria, anche con riferimento ai casi di oblazione proposta nelle indagini preliminari
