Synergistic effects of sequential treatment by UV irradiation and chemical disinfectant for drinking water disinfection
Abstract The sequential use of disinfection strategies for drinking water treatments has been shown to provide levels of inactivation greater than those corresponding to the single-step disinfection effects (Corona-Vasquez et al., 2002; EPA, 1999). Therefore, a disinfectants combined system could be applied both for the inactivation of microorganisms, resistant to traditional treatments, and al...
متن کاملImproved wastewater disinfection by ultrasonic pre-treatment.
The objective of our work is to evaluate the scientific and economic potential of US application as a pre-treatment step in combination with UV to optimise the disinfection process of wastewaters. Ultrasound application of 20 s at low density of 30 W/l changed the particle size distribution (PSD) of the samples, the mean particle diameter dropped from 70 to 11 microm. Generally it is assumed th...
متن کاملElectrochemical disinfection of secondary wastewater treatment plant (WWTP) effluent.
In this work the electrochemical disinfection of the effluent of a secondary wastewater treatment plant is investigated. In the experimental work, performed on-site with real effluents of the WWTP located in Vuelta Ostrera (Cantabria, Spain), boron-doped diamond (BDD) electrodes were employed. The initial concentration of E. coli in the effluent of the WWTP varied in the range 1.3 x 10⁴-5.2 x 1...
متن کاملThe Effect of UV and Combined Chlorine/UV Treatment on Coliphages in Drinking Water Disinfection
Ultraviolet (UV) irradiation is a common way to disinfect drinking water, but some viruses are very resistant to UV. Drinking water was disinfected with UV after spiking with MS2 and 18 different coliphages isolated from municipal wastewater effluent. In addition, some coliphages were disinfected with combined treatment of chlorine/UV or vice versa with UV/chlorine. A UV-dose of 22 mWs/cm2 caus...
متن کاملThe antagonistic and synergistic effects of temperature during solar disinfection of synthetic secondary effluent
A 4-factor, multilevel, full factorial design of 240 experiments was performed in order to investigate the effect of temperature on the inactivation efficiency of spiked Escherichia coli in simulated solar disinfection of a synthetic secondary effluent. The initial population of the microorganisms was 10, 10, 10 and 10 CFU/mL, the exposure time 1, 2, 3 and 4 h, the treatment temperature 20, 30,...
