Evaluation of Decolorization, Mineralization, and Toxicity Reduction of an Azo Dye C.I. Reactive Black 5 in a Countercurrent Bubble Column by Ozone
Publisher: American Society of Civil Engineers
Abstract: A countercurrent and continuous-flow design bubble column reactor (BCR) was used to investigate variations in traditional parameters of water-containing Reactive Black 5 (RB5) under different gas/liquid flow rates. RB5 is ...
Establishment and Implementation of Source Water Implementation Plan for Water Treatment Plants in Taiwan
Publisher: American Society of Civil Engineers
Abstract: In accordance with the source water implementation plan rule (SWIPR) in Taiwan, water treatment plants (WTPs) with source water parameters exceeding the source water quality standards are required to submit a source water ...
Effects of Surface Characteristics of Activated Carbons on VOC Adsorption
Publisher: American Society of Civil Engineers
Abstract: Surface characteristics of activated carbons can play critical roles on adsorption performance of volatile organic compounds (VOCs). Attempts were made to correlate the specific physicochemical characteristics of various ...
Detection, Occurrence, and Treatment of Nonylphenol and Bisphenol-A in Taiwanese Drinking Water Sources
Publisher: American Society of Civil Engineers
Abstract: This study investigated the occurrence and treatment of endocrine disrupting chemicals (EDCs), i.e., nonylphenol (NP) and bisphenol-A (BPA), in Taiwanese drinking water sources. The performance of coagulation-sedimentation ...
Effect of Bromide and Ammonia on the Formation of Ozonation and Chlorination By-Products
Publisher: American Society of Civil Engineers
Abstract: The objective of this investigation was performed to assess the effects of bromide and ammonia concentrations on the formation of ozonation and chlorination by-products including bromate, trihalomethanes (THMs), and ...
Reduction of Natural Organic Matter and Disinfection By-Product Precursors by Coagulation and Adsorption
Publisher: American Society of Civil Engineers
Abstract: Source water from King-Men Reservoir water in Taiwan was treated by alum and polyaluminum chloride coagulation, and the corresponding natural organic matter was fractionated by ultrafiltration membranes for determining its ...
Evaluation of Source Water Quality Standards for Total Coliforms, TOC, and COD in Taiwan
Publisher: American Society of Civil Engineers
Abstract: The objective of this research is to review the current status of source water as compared with the Taiwanese source water quality standards promulgated in 1997. The total coliforms, total organic carbon (TOC) and chemical ...
