Chlorine in water disinfection
Disinfection of drinking-water is one of the main achievements of our time in the protection of public health. The use of chlorine for the destruction of microbiological pathogens is essential to protect the public from outbreaks of waterborne disease. Chlorine, as well as other disinfectants, produces a variety of chemical by-products. The risk from the presence of microbial pathogens in drink...

Veterinary antibiotics are widely used at concentrated animal feeding operations (CAFOs) to prevent disease and promote growth of livestock. However, the majority of antibiotics are excreted from animals in urine, feces, and manure. Consequently, the lagoons used to store these wastes can act as reservoirs of antibiotics and antibiotic-resistant bacteria. There is currently no regulation or con...
متن کاملAnilines Oxidation with Chlorine Dioxide in Wastewater
Oxidative behaviors of three toxic pollutants including aniline, p-toludine and p-chloroaniline with ClO2 in water were studied with HPLC. The removal rates of anilines were used as criteria in this experiment. Effects of the ClO 2 concentration, pH and reaction time on the removal rate of anilines were discussed. The results show that for 1mmol ·L-1 aniline, p-toludine and p-chloroaniline, the...
متن کاملKinetics and mechanism of bacterial disinfection by chlorine dioxide.
Survival data are presented for a fecal strain of Escherichia coli exposed to three concentrations of chlorine dioxide at four temperatures. Chick's first-order reaction equation is generalized to a pseudo nth-order model. Nonlinear least squares curve-fitting of the survival data to the nth order model was performed on an analogue computer. The data were observed to follow fractional order kin...
