Sulfur-based mixotrophic denitrification with the stoichiometric S(0)/N ratio and methanol supplementation: effect of the C/N ratio on the process.
Yánez D, Guerrero L, Borja R, Huiliñir C. Yánez D, et al. J Environ Sci Health A Tox Hazard Subst Environ Eng. 2021;56(13):1420-1427. doi: 10.1080/10934529.2021.2004839. Epub 2021 Dec 1. J Environ Sci Health A Tox Hazard Subst Environ Eng. 2021. PMID: 34851232
The impact of the organic carbon to nitrate ratio (C/N ratio) on mixotrophic denitrification rate has been scarcely studied. ...For this, two initial concentrations of NO(3)(-)-N (50 and 25 mg/L) at a stoichiometric ratio of S(0)/N, and four initial C/N ratios (0, 0 …

Fly ash as stimulant for anaerobic digestion: effect over hydrolytic stage and methane generation rate.
Guerrero L, Da Silva C, Barahona A, Montalvo S, Huiliñir C, Borja R, Peirano C, Toledo M, Carvajal A. Guerrero L, et al. Water Sci Technol. 2019 Oct;80(7):1384-1391. doi: 10.2166/wst.2019.391. Water Sci Technol. 2019. PMID: 31850890
Thermoelectric fly ash was used as a micronutrient source for microorganisms in the anaerobic digestion process of thermally pretreated (1 hour, 120 C) secondary sludge. The obtained results not only suggest that fly ash improves methane generation in the conversion of vol …

Valorization of oat husk by hydrothermal carbonization: Optimization of process parameters and anaerobic digestion of spent liquors.
Murillo HA, Pagés-Díaz J, Díaz-Robles LA, Vallejo F, Huiliñir C. Murillo HA, et al. Bioresour Technol. 2022 Jan;343:126112. doi: 10.1016/j.biortech.2021.126112. Epub 2021 Oct 11. Bioresour Technol. 2022. PMID: 34648962
Optimal hydrochar MY (53.8%) and HHV (21.5 MJ/kg) were obtained for 219.2 C, 30 min, and 0.08 of biomass/water ratio. A successful prediction capability of the optimization approach was observed, archiving an error < 1% between predicted and validated responses. ...

Modeling of the denitrification/anaerobic digestion process of salmon fishery wastewater in a biofilm tubular reactor.
Huiliñir C, Aspé E, Roeckel M. Huiliñir C, et al. J Environ Manage. 2011 Jun;92(6):1591-608. doi: 10.1016/j.jenvman.2011.01.015. Epub 2011 Feb 12. J Environ Manage. 2011. PMID: 21320744
Based on our results, we concluded that the removal of organic matter and nitrogen compounds depended mainly on HRT. The effluent pH was mainly affected by the C/N ratio, where a decrease increases pH. Organic matter removal was related with the anaerobic digestion process …
