“…Several case studies have demonstrated the applicability of modelling and simulation for the design purposes ranging from simple small plants to complex large plants (Daigger and Nolasco 1995;Bingley and Upton 2000;Gabaldon et al 2000;Larrea et al 2001;Rivas et al 2001;Oleszkiewicz et al 2004;Seco et al 2004). Simulation results can be used not only to make direct decisions on investments but also to verify the proposed design assumptions (Gorgun et al 1996b;Coen et al 1997).…”

“…However, the implementation of this process can cause some handling problems and considerably increase the operating costs, especially at large wastewater treatment plants (WWTPs) (WEF, 2005). For example, Oleszkiewicz et al (2004) estimated that 100 to 150 tons/d of 10% methanol would be needed to remove 2 to 4 g N/m 3 of nitratenitrogen (NO 3 -N) to achieve an effluent limit of total nitrogen of 10 g N/m 3 at the Czajka WWTP in Warsaw (Q 5 580 000 m 3 /d).…”

Food industry effluents are considered a potential alternative for methanol when seeking external carbon sources to enhance denitrification in municipal wastewater treatment plants (WWTPs). The aim of this study was to determine the immediate effects of dosing different carbon sources on the denitrification capability of process biomass from the Wschod WWTP in Gdansk (northern Poland). Five carbon sources, including settled wastewater, methanol, and three industrial effluents (distillery, brewery, and fish-pickling process) were tested in two kinds of batch experiments. The acclimation period of biomass to methanol also was investigated in bench-scale systems. During the conventional batch experiments, with the industrial effluents, the observed nitrate utilization rates (NURs) ranged from 2.4 to 6.0 g N/(kg VSS?h), which were only slightly lower than the rates associated with the use of the readily biodegradable fraction in the municipal (settled) wastewater [4.6 to 7.8 g N/(kg VSS?h)]. The conventional NURs observed with methanol and non-acclimated process biomass were low [i.e., 0.4 to 1.5 g N/(kg VSS?h)], and a minimum 2-week acclimation period of biomass to methanol in the bench-scale systems was needed to reach the level of 4.0 g N/(kg VSS?h). In other experiments, dosing the distillery and fish-pickling effluents at the beginning of the anoxic phase (preceded by the anaerobic phase) resulted in considerably higher (over 20%) NURs compared with the same experiments with the other carbon sources.

“…This was especially ideal for short-term solution, but also viable for long term if a cheap and abundant external carbon sources could be secured. Hence, finding an alternative cost-effective external carbon substance was listed amongst the priorities of the wastewater treatment industry during WEF 2005 [8] and have been going on for the past two decades [12]. The focus was mostly on local industrial waste products/ by-products that is rich in carbon, where they were addressed to be 'highly recommended especially if one WWTP can has the access' [12].…”

The study examined the potential of fermented and dark-fermented biosolids as external carbon sources for denitrification improvement. This was done by up-scaling the selected two (out of seven) sludge fermentation conditions from past studies, carrying out ammonia stripping pre-treatment to fix the C/N ratio, before finding their specific denitrification rate (SDNR) using SDNR experiment set-up. The gotten SDNR were then compared to the SDNR of other substances gotten from both previous studies and literature, to weight the denitrification potential of fermented biosolids as a substance. The results found that with an initial COD of 607-704 mgCOD/L, the SDNR of the two fermented biosolids and dark fermented biosolids were found to be 8.35 ± 0.41 and 8.56 ± 0.71 respectively. This was much higher than the 1.53 -2.57 for sucrose and 1.29 ± 0.21 for wastewater found in earlier study using the same methodology; and comparable to the denitrification potential value for the well-studied methanol
