Efficiency of water service management alternatives in Spain considering environmental factors

The main aim of this study is to identify the most efficient forms of management for municipal water supply services, taking into account exogenous factors. The study is based on a sample of 1518 Spanish municipalities, all with 1000 to 50,000 inhabitants, for the year 2019. The study method consists of analysing order-m partial frontiers subjected to environmental factors. The main results obtained indicate that mixed management forms achieve the highest levels of efficiency.Andalusian Regional Government, Grant Number: P20.00605University of Granada (FEDER funding), Grant Number: A.SEJ.351.UGR18Ministry of Science and Innovation, Grant Number: PID2021- 128713OB-I0University of Granada "AYUDAS DEL PLAN PROPIO UGR 2022", Grant Number: PPJIA2022-5

Enhanced ammonia removal at room temperature by pH controlled partial nitrification and subsequent anaerobic ammonium oxidation

This is the post-print reviewed version of the following article: U. Durán, A. Val del Río, J.L. Campos, A. Mosquera-Corral & R. Méndez (2014) Enhanced ammonia removal at room temperature by pH controlled partial nitrification and subsequent anaerobic ammonium oxidation, Environmental Technology, 35:4, 383-390, DOI: 10.1080/09593330.2013.829110, which has been published in final form at http://dx.doi.org/10.1080/09593330.2013.829110. This article may be used for non-commercial purposesThe Anammox based processes are suitable for the treatment of wastewaters characterized by a low carbon to nitrogen (C/N) ratio. The application of the Anammox process requires the availability of an effluent with a NO2--N/NH4+-N ratio composition around 1 g·g-1, which involves the necessity of a previous step where the partial nitrification is performed. In this step the inhibition of the nitrite oxidizing bacteria (NOB) is crucial. In the present work a combined partial nitrification-Anammox two units system operated at room temperature (20 ºC) has been tested for the nitrogen removal of pre-treated pig slurry. To achieve the successful partial nitrification and inhibit the NOB activity different ammonium/inorganic carbon (NH4+/IC) ratios were assayed from 1.19 to 0.82 g NH4+-N·g-1 HCO3-C. This procedure provoked a decrease of the pH value to 6.0 to regulate the inhibitory effect over ammonia oxidizing bacteria (AOB) caused by free ammonia (FA). Simultaneously the NOB experienced the inhibitory effect of free nitrous acid (FNA) which avoided the presence of nitrate in the effluent. The NH4+/IC ratio which allowed the obtaining of the desired effluent composition (50% of both ammonium and nitrite) was of 0.82±0.02 g NH4+-N g-1 HCO3--C. The Anammox reactor was fed with the effluent of the partial nitrification unit containing a NO2--N/ NH4+-N ratio of 1 g·g-1 where a nitrogen loading rate (NLR) of 0.1 g N·L-1·d-1 was efficiently removedThis work was supported by CONACyT-México economic support [grant number 147817]; Xunta de Galicia [grant number10MDS265003PR]S

Modeling political mimetic isomorphism versus economic and quality factors in local government privatizations

Numerous studies have considered the economic impact and political influence of privatization. However, the theoretical approaches previously applied to model privatization, whether economic or political, have not obtained robust results. To address this question, we present a new political approach, based on mimetic isomorphism, which enables us to more accurately define the relationship between privatization, political theory and economic aspects. This new focus, termed political mimetic isomorphism, hypothesizes that the privatization of public services is influenced by an imitation effect between neighboring municipalities that share a common political ideology. In our study, this approach is applied, using geostatistical tools and logistic regression analysis with spatial variables, to a sample of municipalities that privatized their water and/or waste collection services during the period 2014–2019. The results obtained demonstrate the validity of the theoretical model of political mimetic isomorphism and show that this factor exerts a stronger influence on privatization than certain economic variables.Agencia de Innovación y Desarrollo de Andalucía, Grant/Award Number: P20_000605Ministerio de Ciencia e Innovación, Grant/Award Numbers: PID2021-128713OB-I00, MCIN/AEI/10.13039/501100011033/yporFEDERUnamaneradehacerEuropaUniversidad de Granada, Grant/Award Number: B-SEJ-476-UGR20Funding for openaccess charge, Grant/Award Number: UniversidaddeGranada/CBU

Biomass aggregation influences NaN3 short-term effects on anammox bacteria activity

The main bottleneck to maintain the long term stability of the partial nitritation-anammox processes, especially those operated at low temperatures and nitrogen concentrations is the undesirable development of nitrite oxidizing bacteria (NOB). When this occurs, the punctual addition of compounds with the capacity to specifically inhibit NOB without affecting the process efficiency might be of interest. Sodium azide (NaN3) is an already known NOB inhibitor which at low concentrations does not significantly affect the ammonia oxidizing bacteria (AOB) activity. However, studies about its influence on anammox bacteria are unavailable. For this reason the objective of the present study was to evaluate the effect of NaN3 on the anammox activity. Three different types of anammox biomass were used: granular biomass comprising AOB and anammox bacteria (G1), anammox enriched granules (G2) and previous anammox granules disaggregated (F1). No inhibitory effect of NaN3 was measured on G1 sludge however the anammox activity decreased in the case of G2 and F1. Granular biomass activity was less affected (IC50 90 mg/L, G2) than flocculent one (IC50 5 mg/L, F1). Summing up not only the granular structure protects the anammox bacteria from the NaN3 inhibitory effect but also the AOB act as a barrier decreasing the inhibitionThe authors want to thank the Pioneer_STP (ID 199) project funded by the WaterWorks2014 Cofunded Call (Water JPI/Horizon 2020).

Stability of aerobic granular biomass treating the effluent from a seafood industry

This is the pre-print previous reviewed version of the following article: Val del Rio, A., Figueroa, M., Mosquera-Corral, A., Campos, J. L., & Mendez, R. (2013). Stability of Aerobic Granular Biomass Treating the Effluent from A Seafood Industry. International Journal of Environmental Research, 7(2), 265-276, which has been published in final form at https://ijer.ut.ac.ir/article_606_0.html. This article may be used for non-commercial purposesThe aerobic granular systems represent a good alternative to substitute the conventional activated sludge process in the treatment of industrial effluents due to the lower surface requirements. In this work the effluent from a seafood industry, characterized by a high variability and the presence of residual amounts of coagulant and flocculant reagents, was used to study the development of aerobic granular biomass and its stability. In a first stage with OLRs between 2 and 5 kg CODS/m3∙d the development of aerobic granular biomass was promoted with good physical properties: SVI of 35 mL/g TSS, density of 60 g VSS/Lgranule and average diameter of 2.8 mm. In a second stage the continuous change in the OLR applied from 3 to 13 kg CODS/m3∙d, to simulate the real conditions of the industry, showed that the removal of organic matter was not affected (90%) but the aerobic granules disintegrated. The maximum OLR treated in the system without granules disintegration was around 4.4 kg CODS/m3∙d. The nitrogen removal was 30% (for biomass assimilation) and the maximum ammonia removal was around 65% and depending on the solids retention time, the free ammonia concentration and the average granule diameterThis work was funded by the Spanish Government (TOGRANSYS CTQ2008-06792-C02-01, NOVEDAR_Consolider CSD2007-00055), Xunta de Galicia (project coordinated by Espina y Delfin S.L.

Filamentous bacteria existence in aerobic granular reactors

“The final publication is available at Springer via http://dx.doi.org/10.1007/s00449-014-1327-x”Filamentous bacteria are associated to biomass settling problems in wastewater treatment plants. In systems based on aerobic granular biomass they have been proposed to contribute to the initial biomass aggregation process. However, their development on mature aerobic granular systems has not been sufficiently studied. In the present research work, filamentous bacteria were studied for the first time after long-term operation (up to 300 days) of aerobic granular systems. Chloroflexi and Sphaerotilus natans have been observed in a reactor fed with synthetic wastewater. These filamentous bacteria could only come from the inoculated sludge. Thiothrix and Chloroflexi bacteria were observed in aerobic granular biomass treating wastewater from a fish canning industry. Meganema perideroedes was detected in a reactor treating wastewater from a plant processing marine products. As a conclusion,the source of filamentous bacteria in these mature aerobic granular systems fed with industrial effluents was the incoming wastewaterThis work was funded by the Spanish Government through NOVEDAR Consolider (CSD2007-00055) and PLASTICWATER (CTQ2011-22675) projects.
