RISEvaluation 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 ...
Reduction of Low-MW Model Compounds by Ozonation and O3 ∕UV Processes
Publisher: American Society of Civil Engineers
Abstract: In this investigation, the low-molecular-weight organic matters, such as resorcinol, phloroglucinol, and
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 ...
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 ...
Removal of Model Organic Precursors by Coagulation
Publisher: American Society of Civil Engineers
Abstract: Low-molecular-weight organics, i.e., phloroglucinol (P), resorcinol (R), and p-hydroxybenzoic acid (PHBA), were selected as the target compounds to evaluate their removal and precursor reduction efficiency by coagulation ...
Development and Implementation of Performance Evaluation System for a Water Treatment Plant: Case Study of Taipei Water Treatment Plant
Publisher: American Society of Civil Engineers
Abstract: To implement performance assessment, it is necessary to develop adequate and representative performance indicators. Good performance indicators can specify the measurable evidence that is necessary to document the achievement ...
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 ...
Adsorption–Desorption Rate of Nonpolar Volatile Organic Compounds onto Activated Carbon Exemplified by C6H6 and CCl4
Publisher: American Society of Civil Engineers
Abstract: This investigation was to evaluate the performance of a thermodynamic model using nonlinear driving force in conjunction with the Langmuir model exemplified by the adsorption of benzene and carbon tetrachloride onto activated ...
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 ...
