“…The sludge specific production value and the other parameters characterizing in period A the SBBR during the interval between two washing steps are reported in Table 6. The SSP value reported in this table (i.e., 0.1 kg VSS/ kgCODremoved) is much lower than those commonly reported for continuous biofilm reactors usually falling in the range 0.3-0.5 kgVSS/kgCODremoved (35)(36)(37)(38). Such a rather low production of sludge resulted substantially the same throughout the whole experimentation and was confirmed by the measured very low phosphorus consumption (1.7 gPO4-P/ kgCODremoved).…”

The paper reports the results of an investigation aimed to evaluate the performances of an innovative process for treating tannery wastewater. In such a process biological degradation, carried out in a sequencing batch biofilm reactor (SBBR), is combined with chemical oxidation by ozone. The treatment was carried out at laboratory scale on a real primary effluent coming from a centralized plant treating the wastewater of a large tannery district in Northern Italy. SBBR performances without and with ozonation were compared with very satisfactory results particularly in the latter instance when the recorded COD, TKN, and TSS average removals, (96%), (92%), and (98%), respectively, permitted to achieve the fixed limits enforced by Italian regulation without needing any additional polishing step. With or without ozonation, the process that resulted was characterized by a specific sludge production (0.1 kgVSS/kg CODremoved) significantly lower than the values featuring conventional biological systems (i.e., 0.3-0.5 VSS/kg CODremoved). Moreover, as in the reactor the biomass density results were very high, i.e., 98 gVSS/Lsludge, it was possible to achieve and maintain biomass concentration as high as 20 gVSS/L.

“…Evaluation campaigns carried out in French treatment plants showed that the highest energy consumption is due to aeration, which consumes on average 87% of the energy related to secondary treatment (Canler and Perret, 1993). The energy balance undertaken by Kleiber et al (1993) in the Perpignan treatment plant (France), covering a period of 12 months, resulted in the following consumption distribution in the secondary treatment: air-process = 83% of the total consumption, SAB washings = 17%.…”

“…The headloss increase recorded in the prototype bed was however slower than that recorded in continuous conventional biofilters [11], where washing operations are usually carried out every 1-2 days causing an excess sludge production as high as 0.5-0.6 kg TSS/kg COD removed [12,13]. On the contrary, as shown in Fig.…”

2009) Influence of hydraulic residence time on the performances of an aerobic granular biomass based system for treating municipal wastewater at demonstrative scale, Desalination and Water Treatment, 4:1-3, 206-211, A B S T R A C TThe paper reports the results of an experimental investigation aimed at confirming at demonstrative scale the performances obtained, at laboratory scale, of an innovative aerobic granular biomass based periodic system (SBBGR) for treating municipal wastewater. A demonstrative SBBGR plant (i.e., a submerged biofilter that operates in a "fill and draw" mode) was built thanks to the financial support of the EU Life programme (PERBIOF project). The results show that after the generation of granular biomass during the start-up period, the SBBGR system was able to remove 80-90% of COD, total suspended solids and TKN in primary effluent from a municipal wastewater treatment plant, independently of the hydraulic residence time investigated (i.e., from 12 down to 3 h). The process was characterised by a very high sludge age value (θc ≈ 150 d) that led to a biomass concentration as high as 35-40 g TSS/L bed and a sludge production much lower than that commonly reported for conventional treatment plants.
