RISVerification of Full-Scale Ozone Contactor Inactivation Performance Using Biodosimetry
Publisher: American Society of Civil Engineers
Abstract: A biodosimetric technique was used to verify the concentration-contact time (CT) values [
Evaluation of Weak and Strong Basic Anion Exchange Resins for NOM Removal
Publisher: American Society of Civil Engineers
Abstract: The feasibility of using ion exchange resins in stirred (suspended) mode operation for the removal of natural organic matter (NOM) from surface water was investigated. Resins were compared in terms of their NOM removal ...
Size and Zeta Potential of Oxidized Iron and Manganese in Water Treatment: Influence of pH, Ionic Strength, and Hardness
Publisher: American Society of Civil Engineers
Abstract: Iron and manganese are commonly found in natural waters, particularly in groundwater. Because of the importance of particle size distribution (PSD) on the performance of removal processes, this research focuses on understanding ...
Impact of Media Aging on the Removal of <i>Cryptosporidium</i> in Granular Media Filters
Publisher: American Society of Civil Engineers
Abstract: A study was conducted to assess the impact of media aging on
Assessing Alternative Media for Ballasted Flocculation
Publisher: American Society of Civil Engineers
Abstract: Most current commercial applications of ballasted flocculation use silica sand to increase floc size and density. Other ballast media with different specific gravity may offer advantages such as increased applicable ...
