Effect of ammonia load on efficiency of nitrogen removal in an SBBR with liquid-phase circulation

Abstract: -The removal of biological nitrogen from a synthetic wastewater with different ammonium nitrogen concentrations (50 and 100 mgN-NH 4 + /L) by a nitrification and denitrification process using a sequencing batch biofilm reactor (SBBR) with liquid-phase circulation was studied. The system with a total working volume of 4.6 L (3.7 L in the reactor and 0.9 L in the reservoir) treated 2.1 L of synthetic wastewater in 12-h cycles. As inoculum two types of biomass were used: an anaerobic/anoxic one from an up-flow an… Show more

“…For case (1), control variables are discretized into10, 20 stages; for case (2), control variables are discretized into 11, 20 stages. Our experiment results are listed in Table 4, along with those results obtained by Luus with IDP, [7] Balsa-Canto et al with restricted secondorder information (RSOI), [3] Shelokar et al with multicanonical jump walk annealing assisted by tabu list (MJWAT). [18] Figures 7 and 8 plot control trajectories u and fractional difference graphs for both cases.…”

“…[12,34] [35] problem 4 consists of determination of four control variables of a chemical reactor, which aims to maximize the economic benefit. The problem has been studied by Luus, [7] Balsa-Canto et al, [3] and Shelokar et al [18] The system is described as follows: and the following bounds on the control variables: 0≤u 1 ≤20; 0≤u 2 ≤6; 0≤u 3 ≤4; 0≤u 4 ≤20:…”

“…Many inocula from domestic and industrial sewage treatment plants may contain denitrifying bacteria, mainly in activated sludge systems (Liu et al, 2006;Daniel et al, 2009), where the biological nitrogen removal occurs to promote denitrification, i.e., under heterotrophic anoxic conditions, the organic carbon sources act as electron donors and reduce nitrate to nitrogen gas (Canto et al, 2008).…”
