050084: Methylene Blue Dye Test Strips for Qualitative Detection of Hydroxyl Radicals

Michigan State University’s invention is a method for indicating the presence of hydroxyl radicals in an aqueous solution. The method uses a simple procedure requiring inexpensive materials, without the addition of competitive probe chemicals that potentially can interfere with the reaction. Mythylene blue dye qualitatively indicates the presence...

040138: Ceramic Membrane Filtration of Ozonated Water

Membrane filtration is considered one of the best available technologies for meeting Stage 2 D/DBP requirements. However, one of the major problems with membrane processes is the decrease in permeate water flux resulting from membrane fouling. In addition, although membrane filtration of drinking water provides a barrier against pathogens and particles,...

000032: Purification of Drinking Water Using Ozonation in a Fluidized Bed Bioreactor

The conventional approach to including ozonation in water treatment is to combine it with biological treatment (biotreatment). One problem of conventional ozonation/biodegration processes is that the biodegradable organic carbon (BDOC) in the organic materials formed by the initial ozonation is difficult to quickly remove during the subsequent biotreatment....
