Nitrogen Removal Using Combined Ultracompact Biofilm Reactor-Packed Bed System
Publisher: American Society of Civil Engineers
Abstract: A predenitrification system consisting of an ultracompact biofilm reactor (UCBR) and a packed bed column was used for removing nitrogen from synthetically simulated wastewater. The UCBR column was maintained under aerobic ...
Nonlinear Behavior of Permeate Flux in Full-Scale Reverse Osmosis Processes
Publisher: American Society of Civil Engineers
Abstract: Permeate flux is a key design and operating parameter for the reverse osmosis (RO) process. It has been widely observed from laboratory studies that permeate flux is linearly related to transmembrane pressure, but it has ...
Granulation Enhancement in Anaerobic Sequencing Batch Reactor Operation
Publisher: American Society of Civil Engineers
Abstract: Two laboratory-scale anaerobic sequencing batch reactors (anSBRs) were used to investigate the effectiveness of polymer addition for enhancing granulation. Mixed liquor volatile suspended solids (MLVSS) concentrations in ...
Use of a Sequencing Batch Reactor for Nitrogen and Phosphorus Removal from Municipal Wastewater
Publisher: American Society of Civil Engineers
Abstract: In this study, a suspended growth sequencing batch reactor (SBR) and an attached cum suspended growth SBR were used to investigate the performance characteristics of nitrogen and phosphorus (NP) removal from municipal ...
Study of Heavy Metals in Dredged Spoil
Publisher: American Society of Civil Engineers
Abstract: There is a possibility that dredged sediments can be contaminated with heavy metals because of the recent industrial development and rapid population increase along the coastal regions of the world. Hence there is a need ...
Effect of Acidogenic Stage on Aerobic Toxic Organic Removal
Publisher: American Society of Civil Engineers
Abstract: A laboratory investigation explored treatment of wastewaters containing nitrobenzene, biphenyl, and polynuclear aromatic hydrocarbons (PAHs) by two aerobic reactors, with and without acidogenic pretreatment. A sequencing ...
Simulations of Full-Scale Reverse Osmosis Membrane Process
Publisher: American Society of Civil Engineers
Abstract: Performance of a two-stage full-scale reverse osmosis (RO) process for a desalination plant in Florida was simulated with a mathematical model based on the principles of membrane transport and mass conservation. In this ...
Membrane Bioreactor Process Modeling and Optimization: Ulu Pandan Water Reclamation Plant
Publisher: American Society of Civil Engineers
Abstract: The operating energy efficiency of the Ulu Pandan membrane bioreactor plant is optimized by artificial neural network (ANN) and bioprocess models. The ANN model mines historical plant data to uncover optimal operating ...
