A new immunomagnetic bead separation–surfactant extraction treatment protocol for rapid and sensitive quantitative PCR detection of Cryptosporidium parvum DNA
The Cryptosporidium oocyst is encased in a robust wall that is extremely resistant to detrimental environmental factors such as chlorine used to disinfect potable water. Therefore, extracting oocyst DNA is not a trivial undertaking. Standard procedures used to extract DNA from oocysts, such as freeze–thaw (F/T) methods and DNA purification kits, are time-consuming and expensive and are ...

Free radical destruction of haloacetamides in aqueous solution
Haloacetamides are disinfection byproducts (DBPs) formed through chlorine/chloramine disinfection processes in drinking waters and have been recently highlighted in the US national Reconnaissance Survey. These species occur at low concentrations, but have been determined to have high cytotoxicity and mutagenicity and therefore may represent a human health hazard. Advanced oxidation/reduction ...

Introducing ozone to water purification – Case Study
Traditionally, chlorine has been used to disinfect water for drinking. Unfortunately, chlorine produces carcinogenic by-products called trihalomethanes (THM’s) when it reacts with organic substances in surface waters. The recent adoption of the Surface Treatment Rules by the U.S. E.P.A. places strict limits on chlorine. Because ozone produces fewer disinfecting by-products, the EPA, along ...
