“…Li et al [30] reported a C•t of 140 mg•min/L to inactivate 4.5 log of the same strain. Additionally, it is clear that pH directly influences endospore inactivation, since HClO (pKa = 7.4) is more effective than ClO − (pKa = 7.22) [68]. The C•t values obtained with NaClO in this study occurred within the reported ranges.…”

The disinfection of wastewater is a treatment that allows for its reuse. However, not all pathogenic microorganisms or their resistant structures, e.g., endospores, cysts, or oocysts, are eliminated in conventional treatments. This work compared the removal efficacy of sodium hypochlorite (NaClO) and peracetic acid (PAA) on three strains of bacteria isolated from the tertiary effluent of a wastewater treatment plant. The results of the inactivation kinetics showed that complete inactivation of S. pasteuri was achieved with both NaClO (>12 log, t = 5–10 min, 15–30 mg/L) and PAA (~9 log, t = 20–30 min, 15 mg/L). Likewise, with higher concentration of both disinfectants, the inactivation time decreased. K. pneumoniae showed greater resistance to PAA (3 log, t = 30 min) than to NaClO (8 log, t = 15 min). B. subtilis endospores showed resistance to NaClO (3 log, t = 60–100 min, 15 mg/L); however, PAA was more effective (~4 log, t = 45–100 min), with 15 mg/L regarding these latter four kinetics. The inactivation curves of these strains showed concave and linear tendencies with tail effects, fitting the Weibull and Geeraerd models. Both the inactivation kinetics and the models established for vegetative cells and endospores in this study are conclusive to understand the differences between these biological forms and, consequently, their ability to survive disinfection.

“…La cantidad de solidos suspendidos reflejada como tur bidez fue eliminada por el filtro en valores que oscilaron entre 46,9 y 68,9 %, mientras que la concentración de cloro residual fue eliminada en proporciones de 87,5 a 100 %. El cloro residual es un parámetro impor tante durante el transporte de agua potable de la planta de tratamiento a los hogares; sin embargo, al ser un compuesto potencial mente formador de agentes cancerígenos (King & Marrett, 1996;Drogui & Daghrir, 2015) en altos niveles sería, importante eliminarlo del agua antes de beberla, pues adicionalmente cambia las propiedades organolépticas del agua potable.…”

In recent years there has been an increase in cardiovascular disease, cancer, diabetes and neurodevelopmental disorders such as autism and attention deficit disorder. The causes of diseases and disorders are multifactorial. However, according to recent studies, special emphasis is placed on nutritional causes. Specific foods appear to cause damaging effects on health and the brain. In this paper, the negative results of 15 white foods in the diet are investigated, such as sugar, white flour and rice, meat, milk, but also flavor enhancers, sweeteners, alcohol, and others.
