Adopting of drink water conditions needs sterilization from the resource. There are many used matter to sterilize, but the most use is by Chloride, so it is necessary to obtain solutions because of continuous damages due to sterilization operation.
The water sterilization by chloride may create secondary compounds in water, which are very dangerous. Those compounds are as Trihalomethanes (THMs) which cause crabs. Therefore, we researched the sterilization by chloride in comparison with other ways. In addition, we get rid off hydro carbonates from sterilized drink water samples, which were obtained from different resources, drink water, natural water and dames using the activated carbon to get rid off venole and humic acids not to interact with chloride and cause people cansers.
This study discusses in-duct UVGI efficiency to disinfect O.R and ICU supplied air. Experiment
setup was designed using three ultraviolet lamps were placed at the upper side of experimental duct,
equipped with variable speed turbine to simulate flo
w rates of ICU and O.R. In order to determine
organism irradiance time, UV intensity distribution is measured at different levels in duct, Thenthese
parameters combined in simulation program executed under LABVIEW programming environment to
determine in-duct disinfection efficiency in relation to ICU and O.R designing requirement and sterility
level.
The hydrodynamic activation of NaOCL plays an important role in increasing
its disinfectant efficacy.
The aim of this study was to evaluate the efficacy of a 5.25% sodium hypochlorite Activated by
EndoActivator device in reducing the bacterial load in the infected root canal.
