Removal of Waterborne Microorganisms by Filtration
نویسندگان
چکیده
19 Clay-polymer composites were designed for use in filtration processes for disinfection 20 during the course of water purification. The composites were formed by sorption of 21 polymers based on starch modified with quaternary ammonium ethers onto the 22 negatively charged clay mineral bentonite. The performance of the clay-polymer 23 complexes in removal of bacteria was strongly dependent on the conformation adopted 24 by the polycation on the clay surface, the charge density of the polycation itself and the 25 ratio between the concentrations of clay and polymer used during the sorption process.

Drinking water treatment processes for removal of Cryptosporidium and Giardia.
Major waterborne cryptosporidiosis and giardiasis outbreaks associated with contaminated drinking water have been linked to evidence of suboptimal treatment. Cryptosporidium parvum oocysts are particularly more resistant than Giardia lamblia cysts to removal and inactivation by conventional water treatment (coagulation, sedimentation, filtration and chlorine disinfection); therefore, extensive ...
متن کاملPrevention and control of health care-associated waterborne infections in health care facilities.
The current article is a review of the public health risks attributable to waterborne pathogens in health care. The consequences of health care-associated infections (HAIs) are discussed. Not only are Legionella spp involved in HAIs, but also Pseudomonas aeruginosa, other gram-negative microorganisms, fungi, and amoeba-associated bacteria. This is particularly noteworthy among immunocompromised...
متن کاملGlycerin Removal from Ultrafiltration Flat Sheet Membranes by Filtration and Soaking
comIn the case of pharmaceutical processes, the presence of preservatives can be problematic and the quantity is subject to stringent standards. So, the aim of this study is to quantify the removal of glycerin contained in ultrafiltration flat sheet membranes by filtration and soaking. This is carried out over a wide range of membranes with different characteristics. The selected flat sheet mem...
متن کاملEstimation of norovirus removal performance in a coagulation-rapid sand filtration process by using recombinant norovirus VLPs.
Norovirus (NV) is an important human pathogen that causes epidemic acute nonbacterial gastroenteritis worldwide. Because of the lack of a cell culture system or an animal model for this virus, studies of drinking water treatment such as separation and disinfection processes are still hampered. We successfully estimated NV removal performance during a coagulation-rapid sand filtration process by...
متن کاملEffects of Drinking-Water Filtration on Cryptosporidium Seroepidemiology, Scotland
Continuous exposure to low levels of Cryptosporidium oocysts is associated with production of protective antibodies. We investigated prevalence of antibodies against the 27-kDa Cryptosporidium oocyst antigen among blood donors in 2 areas of Scotland supplied by drinking water from different sources with different filtration standards: Glasgow (not filtered) and Dundee (filtered). During 2006-20...
