Development and pilot-scale validation of a fuzzy-logic control system for optimization of methane production in fixed-bed reactors
2018
International audience; The objective of this study was to develop an advanced control system for optimizing the performance of fixed-bed anaerobic reactors. The controller aimed at maximizing the bio-methane production whilst controlling the volatile fatty acids content in the effluent. For this purpose, a fuzzy-logic controller was developed, tuned and validated in an anaerobic fixed-bed reactor at pilot scale (350 L) treating raw winery wastewater. The results showed that the controller was able to adequately optimize the process performance, maximizing the methane production in terms of methane flow rate, resulting in an average methane yield of about 0.29 LCH4 g−1 COD. On the other han…
Noise risk assessment in a bottling plant of a modern Italian winery
2014
In the wine industry, bottling is a phase of the production cycle characterized by high levels of noise, mostly owing to repeated collisions between the bottles. In Italy, the Law Decree 81/2008 defined the requirements for assessing and managing noise risk, identifying a number of procedures to be adopted at different noise levels to limit worker exposure. This study was aimed at evaluating the equivalent and peak noise level inside the bottling plant area of a modern Italian winery. In particular, the influence of the working capacity (number of bottles produced per hour) on noise levels was evaluated. Three test conditions were considered: T1 with a working capacity of 4000 bottles/h; T2…
The Dolia Defossa and viticulture at Vagnari
2022
At Vagnari, the fabric of the dolia defossa was distinctively different from that present in all the other ceramics from the site, as it was a distinctive orangey-red with black, glassy particles and reddish-brown grit fragments. The surviving lid fragment, on the other hand, is made of a fairly fine buff clay, suggesting it was made somewhere else. It is not unusual that dolia and lids might be made of different clays and in different workshops, as they are in Gallia Narbonensis, where some analysed lids were made in Rome, but the vessels were local. The recognition that it is important to conduct fabric analyses on dolia retrieved in archaeological excavations, whether on land or in the s…
