Review of swimming-associated cryptosporidiosis and Cryptosporidium oocysts removals from swimming pools
In this paper, outbreaks of cryptosporidiosis in swimming pools in the last 20 years are summarized. Cryptosporidium oocysts are very resistant to many disinfectants, including chlorine, one of the most widely-used disinfectants in swimming pools. Ozone or UV is shown to inactivate Cryptosporidium, while not effective to newly introduced Cryptosporidium and bacteria because of no residual ozone ...
A pilot-scale study of Cryptosporidium-sized microsphere removals from swimming pools via sand filtration
Cryptosporidium species are the most common cause of gastrointestinal illness in treated recreational water venues. In order to protect public health during swimming, Cryptosporidium-sized microsphere removals by high-rate sand filtration with six coagulants were evaluated with a 5.5 m3 pilot-scale swimming pool. A sand filter without coagulation removed 20–63% of ...
