Electrocoagulation of Silica Nanoparticles in Wafer Polishing Wastewater by a Multichannel Flow Reactor: A Kinetic Study
Publisher: American Society of Civil Engineers
Abstract: A simplistic and systematic procedure has been developed for the design and upscaling of a multichannel, continuous-flow electrocoagulation reactor of monopolar configuration for the removal of submicron particles from ...
Biotrickling Filtration for Control of Volatile Organic Compounds from Microelectronics Industry
Publisher: American Society of Civil Engineers
Abstract: This study investigated the transient and steady-state performance of a bench-scale biotrickling filter for the removal of an organic mixture (acetone, toluene, and trichloroethylene) typically emitted by the microelectronics ...
Mixing Water Treatment Residual with Excavation Waste Soil in Brick and Artificial Aggregate Making
Publisher: American Society of Civil Engineers
Abstract: A large quantity of water treatment residual is generated each year from fresh water treatment plants in Taiwan. Landfill disposal of the nonhazardous sludge is impractical because of the high cost of transportation and ...
Special Issue on Advances in Research and Development of Sustainable Environmental Technologies
Publisher: American Society of Civil Engineers
Fouling Mitigation by TiO2 Composite Membrane in Membrane Bioreactors
Publisher: American Society of Civil Engineers
Abstract: Membrane bioreactors (MBRs) have attracted widespread attention in advanced water treatment because of their production of consistent and high-quality effluent. However, membrane fouling during operation has greatly hindered ...
Comparison of Autotrophic and Mixotrophic Biofilters for H<sub>2</sub>S Removal
Publisher: American Society of Civil Engineers
Abstract: We demonstrate that the facultative chemoautotroph
Effects of Surfactant Addition on Dewatering of Alum Sludges
Publisher: American Society of Civil Engineers
Abstract: In Taiwan, surfactants are frequently used in the flotation process to aid in solid/liquid separation. Their effect on the dewatering of alum sludge was investigated. Various amounts of cationic and anionic surfactants ...
Graphite Supported Stainless-Steel Electrode for the Degradation of Azo Dye Orange G by Fenton Reactions: Effect of Photo-Irradiation
Publisher: American Society of Civil Engineers
Abstract: An electrode, stainless steel supported on graphite, was used for the degradation of hazardous organic compounds, azo dye Orange G (OG), using the photoelectro- Fenton (PEF) process. Results showed that the applied current ...
Treating High-Turbidity Water Using Full-Scale Floc Blanket Clarifiers
Publisher: American Society of Civil Engineers
Abstract: Dynamic responses of the blanket in full-scale flat-bottom type floc blanket clarifiers at the PingTsan Water Works, Taiwan Water Supply Corporation, were monitored given a step-change in coagulant (polyaluminum chloride, ...
