A hybrid denitrification – alternate cycles reactor to enhance the nitrogen biological removal in a real wastewater treatment plant / M. Santinelli in Industrial & engineering chemistry research, Vol. 50 N° 24 (Décembre 2011)

Santinelli, Auteur ; A. L. Eusebi, Auteur ; E. Cola, Auteur Année de publication : 2012 Article en page(s) : pp. 13947–13953 Note générale : Chimie industrielle Langues : Anglais (eng) Mots-clés : Hybrid Nitrogen Biological Résumé : This paper involves the retrofitting of a real municipal wastewater treatment plant (WWTP) of 6600 population equivalent (PE), from a traditional biological process to a predenitrification–alternating cycles (PreD-AC) technology, defining a hybrid reactor. The application was investigated for 11 months, from the upgrading in October 2009 to September 2010. The process optimization allowed to reach high standards of effluent’s quality, with total nitrogen (TN) and ammonia (NH4-N) concentrations lower than 15 and 1 mg L–1, respectively. Moreover, the flexibility and automatic control of the process guaranteed an energy consumption decrease of 17%, with a specific energy consumption of 0.18 kWh PETN–1 d–1 as an average value. A reduction of 20% was reached by comparing the sludge amounts disposed in landfills in 2009 and 2010.

The zootechnical anaerobic supernatants / M. Santinelli in Industrial & engineering chemistry research, Vol. 51 N° 15 (Avril 2012)  

Public ISBD [article]  inIndustrial & engineering chemistry research > Vol. 51 N° 15 (Avril 2012) . - pp. 5490-5496 Titre : The zootechnical anaerobic supernatants : Nutrient removal by a biological advanced process Type de document : texte imprimé Auteurs : M. Santinelli, Auteur ; A. L. Eusebi, Auteur ; M. Santini, Auteur Année de publication : 2012 Article en page(s) : pp. 5490-5496 Note générale : Industrial chemistry Langues : Anglais (eng) Mots-clés : Anaerobe Résumé : This paper deals with the evaluation of total nitrogen (TN) removal from zootechnical wastes in a pilot scale reactor, treating digested supernatants by biological way. The high performances in terms of total nitrogen removal by nitrites, greater than 95%, enabled to design a medium scale treatment platform, by combining the anaerobic digestion (AD) and dewatering (DW) units with the alternate cycles (AC) biological process for pig and cattle supernatants. Theoretical mass balances carried out on maximum loading conditions allowed to define an optimal process chain and its sizing. Influent and effluent main parameters were determined for each operation unit, defining a final TN value for pig slurry equal to 14.1 g d-1 head-1 in the dewatered amount and 12.3 g d-1 head-1 from the AC reactor, besides an inner TN load of 49.6 g d-1 head-1. Concerning the cattle slurry treatment, the DW process gained a TN removal of 74%, allowing the AC process to remove the remaining amount of TN of about 30.1 g d-1 head-1. An evaluation of the reliability of a fermentation process to support the anoxic phase of the biological process was further investigated.
