[Legionella spp. contamination in indoor air: preliminary results of an Italian multicenter study].

2014

Obiettivo. Rilevare la presenza di Legionella spp. nell’aria attraverso un protocollo standardizzato, a fianco dei tradizionali metodi impiegati per la rete idrica. Disegno. In dieci strutture sanitarie è stato selezionato un bagno, la cui acqua presentava una contaminazione da Legionella >1.000 unità formanti colonie (ufc)/litro. La contaminazione dell’aria è stata valutata tramite campionamento attivo (Surface Air System, SAS) e passivo, impiegando piastre di sedimentazione per la valutazione dell’Indice Microbico Aria (Index of Microbial Air, IMA). I campionamenti sono stati effettuati per 8 ore consecutive, a circa 1 m dal pavimento e a 50 cm dal rubinetto. Con il campionamento attivo, …

Effect of temperature on anaerobic treatment of black water in UASB-septic tank systems

2007

The effect of northern European seasonal temperature changes and low temperature on the performance of upflow anaerobic sludge blanket (UASB)-septic tanks treating black water was studied. Three UASB-septic tanks were monitored with different operational parameters and at different temperatures. The results indicated the feasibility of the UASB-septic tank for (pre)treatment of black water at low temperatures with respect to removal of suspended solids and dissolved organic material. Inoculum sludge had little effect on COD(ss) removal, though in the start-up phase some poorly adapted inoculum disintegrated and washed out, thus requiring consideration when designing the process. Removal of …
