Indoor Air Quality Overview In modern life, people spend more and more of their time indoors - home, office, cars, and airplanes. A lot of us even exercise indoors. Unfortunately, we've rarely thought about indoor air quality (IAQ) and its health effects, until recently. Sick Building Syndrome and Building Related Illness are related to poor indoor air quality and other indoor environmental factors. More and  more...

Nitrogen Oxides - Abatement and Control Overview Nitrogen oxides (NOx) are a very important family of air polluting chemical compounds. This course explains why NOx are important air pollutants and how NOx are formed and react in the atmosphere. This course also includes the principles on which all NOx control and pollution prevention technologies are based, available NOx technologies for various combustion sources, and performance  more...

Controlling VOCs Using Carbon Adsorbers Overview In air pollution control, adsorption is employed to remove volatile organic compounds (VOCs) from gas streams, when a stringent outlet concentration must be met and/or recovery of the VOC is desired. Although there may be several types of adsorbants used, this course is oriented toward the use of activated carbon, a commonly used adsorbent for VOCs. Of the various types of adsorption  more...

Air Pollution Control Ventilation Equipment The type of equipment needed to convey waste gas are the same for most kinds of control devices. These are: (1) hoods, (2) ductwork, (3) stacks, and (4) fans. Together, these items comprise a ventilation system. A hood is used to capture the emissions at the source; ductwork, to convey them to the control device; a stack, to disperse them after they leave the device; and a fan, to provide the  more...

Gas Absorption for Air Pollution Control Gas absorbers are used extensively in industry for separation and purification of gas streams, as product recovery devices, and as pollution control devices. Absorption is a process where one or more soluble components of a gas mixture are dissolved in a liquid (i.e., a solvent). There are different types of absorption equipment. This course looks at the various absorbers used to control gas  more...

Particulate Control - Baghouses and Filters Overview Fabric filter units are used in industry as an effective pollution control device for removal of particulate material within a captured air stream. This course presents the process descriptions of various styles of baghouses and air filter systems. Design and operating parameters are analyzed. The applicability of filter materials and operating principles are explained for a variety of  more...

Wet Scrubbers for Particulate Matter Control Overview Wet scrubbers are a pollution control devise used in the industry for removal of particulate material within a captured air stream. There are numerous types of wet scrubbers which remove both acid gases and particulate mater (PM). This course describes the commonly applied scrubber designs used to remove PM from stationary sources. Design and operating parameters are presented. Various  more...

Electrostatic Precipitators for Air Pollution Control Overview An electrostatic precipitator (ESP) is a pollution control device that uses electrical forces to move the particles out of the flowing gas stream and onto collector plates for particulate emission control. There are different configurations and types of ESPs designed and operated for removal of particulate mater (PM). This course describes the commonly applied ESP designs used to  more...

Continuous Emission Monitoring EPA has developed a plain-English guide as a ? road map? to help interested parties navigate through the complex Part 75 Continuous Emission Monitoring (CEM) rule. This course will use this guide to study the CEM monitoring requirements for monitoring stack gas emissions. This will be useful to people responsible for complying with the rule, regulatory agencies assessing compliance with the rule,  more...

Thermal Processing of Biosolids Overview Workers in environmental engineering, as design engineers, operators, permitting agency staff, consultants etc. will benefit greatly from a basic understanding of thermal processing systems for biosolids: especially the primary, secondary and tertiary treatment sludge generated in wastewater treatment. This course provides such a capability for both drying and incineration concepts.  more...

Fundamentals of Combustion for Environmental Applications Overview Workers in environmental engineering, as design engineers, operators, permitting agency staff, consultants, etc. will benefit greatly from a basic understanding of the fundamental laws, relationships, and calculation methods that characterize the behavior of combustion systems. This course provides such a capability, introduces the concept of ?wastes as fuels? and gives the diligent  more...
