RISMathematical Modeling and Analysis of the Freezing Process of Drainage Channels in Cold Region Tunnels
Publisher: ASCE
Abstract: In cold regions, the frequent occurrence of frost damage seriously affects the safety and stability of tunnel projects during construction and service time. Analyzing the formation mechanism of ice congestion in the drainage ...
Nitrogen Removal in Moving Bed Sequencing Batch Reactors with Polyurethane Foam Cube and Luffa Sponge Carrier Materials
Publisher: American Society of Civil Engineers
Abstract: Nitrogen removal performance was investigated in a sequencing batch reactor (SBR) and two moving bed sequencing batch reactors (MBSBRs) containing a given proportion (20% v/v) of various carrier materials. The maximum total ...
