Trends in the Application of Permeable Pavement as Sustainable Highway Storm Water Management Option for Safe-Use of Roadways

Autor: Udeme J Ndon

Publikováno v: Journal of Civil & Environmental Engineering.

Accumulation of storm water on road surfaces and the associated runoff result in environmental pollution problems, negative impact on durability of pavement and safety problems for the travelling public. Permeable pavement has been used to reduce imp

Periodic aerated treatment and in-situ bioremediation strategies for polyhalogenated compounds

Autor: Andrew A. Randall, Udeme J Ndon

Publikováno v: Water Research. 33:2715-2720

Polyhalogenated compounds are known to resist aerobic degradation but are subject to anaerobic reductive dehalogenation. The anaerobic biotransformation often result in the accumulation of toxic and carcinogenic compounds. An example is the productio

Analysis and Kinetics of the Sequencing Batch Reactors

Autor: Udeme J. Ndon

Publikováno v: Environmental Engineering Science. 24:505-514

Fundamental analysis and kinetics of treatment reactors are major topics in environmental engineering literature. These fundamental topics in reactor processes are well known for the ideal batch reactor, the continuous stirred tank reactor, and the p

Modeling and computational simulation of dilution and biochemical materials balance equations for partially emptied batch reactors

Autor: Jin C Zhao, Marta Larroya Siguan, Udeme J Ndon

Publikováno v: Applied Biochemistry and Biotechnology. 136:97-118

Sequencing batch reactors (SBRs) including aerobic SBRs and anaerobic SBRs (ASBRs) are partially emptied batch reactors that are widely used as bioprocesses in pollution control. We present dilution and biochemical materials balance modeling equation

Effects of temperature and hydraulic retention time on anaerobic sequencing batch reactor treatment of low-strength wastewater

Autor: Richard R. Dague, Udeme J Ndon

Publikováno v: Water Research. 31:2455-2466

Four laboratory-scale anaerobic sequencing batch reactors (ASBRs) were used to treat synthetic wastewaters at COD concentrations of 1000, 800, 600 and 400 mg/liter (BOD5 of 490, 392, 294 and 196 mg/liter respectively). The ASBRs were operated at temp

Thermal Expansion of Concretes: Case Study in Iowa

Autor: Udeme J. Ndon, K. L. Bergeson

Publikováno v: Journal of Materials in Civil Engineering. 7:246-251

To control the effect of concrete expansion or contraction on the integrity of concrete bridge structures, the thermal coefficient of expansion of concrete is often incorporated into design equations. Current practice is to use the value recommended
