    Comments: Introductory course covering the following topics; overview of environmental legislation; hydrology; water treatment; water quality management; wastewater treatment; and, air pollution.
  • Environmental Engineering II
    Comments: Fundamental concepts of environmental engineering analysis: stoichiometry, kinetics and material balances; reactor design; mathematical models for transport of contaminants. Introduction to Air Pollution Control/Air Quality Management and Solid Waste Management.
  • Environmental Material Balances
    Comments: Developed 20-257-345 “Environmental Material Balances.” Introduction to techniques for the analysis of environmental systems. Applications of concepts of material and energy balances to environmental systems as part of the engineering approach to problem solving.
  • Fluid Mechanics
    Comments: Properties of fluids; fluid statics; kinematics of fluid flow; energy considerations in steady flow; basic hydrodynamics; and, momentum and forces in fluid flow.
  • Mathematical Simulation of Engineering Systems
    Comments: Computer applications in civil engineering; introduction to problem solving; problem solving and algorithms; design of algorithms; efficiency of algorithms; characteristics of mathematical functions; locating zeros and root finding; deterministic simulation; and, probabilistic simulation.
  • Introduction to Air Pollution Control
    Comments: Effects and sources of air pollutants; federal legislation and regulatory trends; meteorology; dispersion of pollutants in the atmosphere; atmospheric photochemical reactions; control of particulates; control of gases and vapors; and, mobile sources.
  • Air Quality Management
    Comments: Objectives are to familiarize students to general aspect of air pollution control and management. Topics include general knowledge of laws and regulations governing the management and control of air pollution in the United States, meteorological impacts on dispersion and transformation of air pollutants and basic principles of control technologies, both for particulate and gaseous air pollutants.
  • Industrial Sources Air Pollution
    Comments: Developed course 20-257-669, "Industrial Sources of Air Pollution." This course has required showing students operating industrial sources of air pollution and reviewing the technical and regulatory requirements for air pollution abatement. The in-class lectures are strengthened with field trips to industrial sources for tours.
  • Diffusion and Mass Transfer in Environmental Systems
    Comments: Developed course 20-257-673, "Diffusion and Mass Transfer in Environmental Systems.” This advanced level course was developed to enhance the ability of environmental students to analyze environmental systems in terms of diffusion and mass transfer. Objectives include to study the fundamentals of diffusion and mass transfer as related to the control of environmental pollutants. Topics covered include analysis of diffusion and mass transfer problems, diffusion in dilute and concentrated solutions, dispersion, mass transfer, determination of mass transfer coefficients, forced convection and gas/solid reactions.
  • Design of Gaseous Pollutant Control Devices
    Comments: This advanced level course was developed and designed to familiarize the student with techniques for controlling gaseous air pollutants. The basic principles of adsorption, absorption, incineration, as well as duct design and fan selection, and the measurement of gas pollutants are covered. In addition, the course includes discussions concerning data required for the design of flue gas desulfurization and denitrification systems.
  • Air Pollution Control Laboratory
    Comments: Developed this gas cleaning laboratory course (20-257-766) in conjunction with course 20-257-674, "Control of Gaseous Pollutants." This involved designing and constructing a mini-liquid gas scrubber capable of illustrating how mass transfer coefficients are obtained by experiments. The data acquisition for this unit is by microcomputers, and helps acquaint the student with modern data acquisition systems.
  • Introduced microcomputers into courses
    Comments: Dr. Keener has consistently been one of the first to introduce students to the advantages of microcomputers. He had the second IBM-PC in the College of Engineering in January, 1983. He required all reports in the Air Pollution Program to be by word processors in 1984, developed a PC based data acquisition laboratory in 1986, and introduced PC's to undergraduate environmental engineering students in 20-257-271 in 1987.
