Environmental Engineering

ENV 305. Heat and Mass Transfer — (3 units)
Prerequisite: ENGR 304 Thermodynamics I.
This course provides an introduction to the fundamental principles of heat and mass
transfer and their application to engineering systems. Topics include steady and transient conduction, forced and free convection and heat transfer, and diffusion mass transfer. Real world problems involving fins and heat exchangers are presented and analyzed.

ENV 401. Environmental Engineering — (3 units)
Prerequisites: ENGR 304 Thermodynamics I
A first course in chemistry (i.e., BSCI 208 Chemistry I or the equivalent) will be very useful. The mass balances conducted in this class rely heavily on some basic chemical knowledge. Also, prior knowledge in fluid mechanics (e.g. ME 401) is beneficial but not essential.
This is an introductory course in environmental engineering. You will study environmental and ecological systems and physical, chemical, and biological processes affecting the fate of chemicals in such systems. You will work problems related to water and wastewater treatment, air pollution, and solid and hazardous wastes. Regulations will be discussed. Also, risk assessment will be used as a means of identifying contaminants of concern. Energy balances will also be discussed.

ENV 402. Thermodynamics of Processes — (3 units)
Prerequisites: ENGR 304 Thermodynamics I, ENV 305 Heat and Mass Transfer.
This course is a 3 unit undergraduate environmental engineering course. It is third in a series of courses covering the fundamental principles of thermodynamics. This course will cover material and energy balances, liquids and mixtures, vapor-liquid equilibria, equilibrium in chemical reactions, and solubility and absorption.

ENV 410. Water Quality Measurements — (3 units)
Prerequisite: ENV 402 Thermodynamics of Processes.
Water is essential for human and other living beings. Therefore, the availability of an adequate water supply in terms of quality and quantity is also essential for the existence of life. This course lays the groundwork for the area of quantitative analysis known as water and wastewater analysis. In Part I, the coursework focuses on the chemistry and microbiological processes and techniques essential for analysis of water and wastewater. Part II addresses methods of analytical measurement for ascertaining the quality and contamination level of water from a wide range of sources.

ENV 420. Air Quality and Air Pollution Measurements — (3 units)
Prerequisites: BSCI 206-Physics I (Mechanics), BSCI 208-Chemistry I, ENV 305-Heat and Mass Transfer
You will investigate the characteristics of the atmosphere, gaseous and particulate air pollution, their sources, effects and controls, and the various methods of measurement, photochemical smog and strategies used to control emissions. Additionally, you will take into consideration various economic issues as defined by welfare effect, public health, and safety issues caused by air and noise pollution within your indigenous areas and prepare solutions of the same.

ENV 425. Groundwater Hydraulics and Hydrology — (3 units)
Prerequisite: ENV 410 Water Quality Measurements.
Groundwater flow, Darcy Law, steady and unsteady flows, confined and unconfined flows, pumps and pump systems.

ENV 430. Principles of Water and Wastewater Engineering — (3 units)
Prerequisite: ENV 401 Environmental Engineering.
Water and wastewater characteristics; physical, chemical and biological methods of treatment.

ENV 440. Hazardous Waste Management — (3 units)
Prerequisite: ENV 402 Thermodynamics of Processes.
Overview of industrial processes which produce hazardous wastes. Principles of toxicology. Federal and state standards. Storage, handling and transport of hazardous waste, and waste minimization.

ENV 520. Transport Phenomena — (3 units)
Prerequisites: Graduate Standing, ENV 402 Thermodynamics of Processes.
Fundamentals of momentum, heat and mass transfer are discussed. Application of fluid mechanics to problems of pollutant transport. Heat and mass transfer operations used in solution of environmental problems.

ENV 530. Environmental Health Risk Assessment — (3 units)
Prerequisite: Graduate Standing.
Topics such as hazardous waste, risk assessment, ground-water contamination, indoor air quality, acid deposition, global climate change, and stratospheric ozone depletion are studied in this course. Qualitative and quantitative aspects of treatment technologies are discussed. Engineering models are based on decision analysis and probabilistic methods.

ENV 550. Combustion and Air Pollution Control — (3 units)
Prerequisites: Graduate Standing, ENV 402 Thermodynamics of Processes.
Principles necessary to understand the sources and control of air pollutants, generation of pollutants in combustion systems, the internal combustion engine, control techniques for particulate and gaseous pollutants.

ENV 560. Chemical Kinetics — (3 units)
Prerequisites: Graduate Standing, ENV 402 Thermodynamics of Processes.
Applications will focus on water and wastewater engineering and a little on air pollution engineering. This course will cover some basic principles of reaction engineering through emphasis on process dynamics in aqueous and gaseous systems.

ENV 580. Advanced Water and Wastewater Treatment — (3 units)
Prerequisite: Graduate Standing.
In-depth discussion of water and wastewater treatment processes; chemical coagulation, flocculation, sedimentation, filtration and absorption and removal methods.

ENV 590. Solid Waste Management — (3 units)
Prerequisite: Graduate Standing.
Human activities generate waste materials that are often discarded because they are considered useless. These wastes are normally solid. The word waste suggests a material that is useless and unwanted. Some waste materials can be reused, and if managed properly, can become a resource for industrial production or energy generation. Waste management has become a significant problem of our time because the American way of life produces enormous amounts of waste. Interestingly, most people want to preserve their lifestyle, while also protecting the environment and public health.

While there have been no revolutionary breakthroughs in waste management options, there has been a steady advance in the technologies necessary to handle solid waste materials safely and economically. Improved management of hazardous waste and the emergence of cost-effective integrated waste management (IWM) systems, with greater emphasis on waste reduction and recycling, have reduced many of the previous problems associated with solid waste management. Also, improved air pollution control devices on incinerators have proven to be effective, and a better understanding of hazardous materials found in solid waste has led to management options that are considered environmentally acceptable.

In this course the following topics will be covered:

  • federal and state legislation
  • characterization of solid waste streams
  • the planning process for municipal solid waste (MSW)
  • methods for reducing the amount of toxicity of sold waste
  • collection and transport of solid waste
  • recycling and markets for recycled products
  • household hazardous wastes and other special wastes
  • composting, incineration, and landfilling
  • siting and costs of MSW facilities.

The overall goal of IWM must be the reduction of the total environmental impact resulting from waste, its handling recycling, treatment or final disposal. Reducing the input to waste management system by increasing the material efficiency of the economy is the preferred long-term option.
