Disinfection is the most essential and final treatment given to drinking water to render the water free from harmful pathogens. The most conventional and common form of disinfection involves the use of strong oxidants that have the potential to produce undesirable disinfection by-products (DBP). Therefore, many researchers have been trying to find alternative disinfection methods to reduce the ...

Despite measures to reduce disease transmission, a risk can occur when blood glucose meters (BGMs) are used on multiple individuals or by caregivers assisting a patient. The laboratory and in-clinic performance of a BGM system before and after disinfection should be demonstrated to guarantee accurate readings and reliable control of blood glucose (BG) for patients. In this study, an effective d...

Cleaning and Disinfection • Little is known about virus survival outside the host; however, HEV is thought to be somewhat stable in the environment since feces are an important source of infection. • Heating pork products to an internal temperature of 71°C (160°F) for 20 minutes is required to completely inactivate HEV. • HEV is potentially susceptible to disinfection with acids like acetic aci...

Conventional drinking water production includes coagulation-flocculation, settling followed by sand filtration and chlorine disinfection. In order to avoid algae proliferation, pre and intermediate chlorination is usually effected. During these previous oxidation steps, water contains higher loads of organics; thus formation of chlorinated disinfection by products (DBP), such as trihalomethanes...

New and emerging infectious diseases pose a threat to public health and may be responsible for nosocomial outbreaks. Cryptosporidium parvum and Escherichia coli are gastrointestinal pathogens that have caused nosocomial infections via person-to-person transmission, environmental contamination, or contaminated water or food. Helicobacter pylori has been transmitted via inadequately disinfected e...

Divalent cationic strontium (Sr2~-l adsorption to and desorption from iron corrosion products were examined in two model drinking water distribution systems (DWDS). One system was maintained with chlorine-disinfected drinking water and the other with the same water with secondary chloramine disinfection. Flow conditions simulated primary transmission lines (constant flow) and residential mains ...
