Introduction to Waste Stream Management: Solid Waste
Improper disposal of hazardous substances removed from both air and water treatment can become solid waste problems. Thermal treatments, like the reciprocating grate incinerator, can be used to eliminate most of the volume of solids. When large am...
Introduction to Waste Stream Management: Gaseous Waste
Gaseous wastestreams present a unique set of challenges. Air pollutants can travel far from their point of origin, causing a variety of health and environmental problems. A range of treatments, including physical, chemical, thermal and biological,...
Introduction to Waste Stream Management: Pollution Prevention
Recycling industrial materials that would otherwise require treatment or landfilling is known as resource recovery and is part of an emerging area of pollution prevention. Some wastes are converted directly into useful energy in municipal waste-to-...
Introduction to Waste Stream Management: Block Flow/Mass Balance Analysis
The first step in controlling wastes is understanding where and how they are generated. Engineers and environmental managers use a tool called a block flow diagram to make sense of complex industrial processes. They also use a technique called mas...
Introduction to Waste Stream Management: Treatment Technologies and Pollution Sources
The approved EPA treatment technologies for solid, liquid and gaseous wastestreams can be categorized into four groups: physical, chemical, biological and thermal. Knowing which type of treatment to use and when to use it requires understanding the...
Introduction to Waste Stream Management: Overview and History of Pollution and Environmental Awareness
While pollution has always been part of the industrial process, environmental accountability is relatively new. The founding of the Environmental Protection Agency and the introduction of basic measures to standardize emissions and treatment of liq...
Introduction to Waste Stream Management: Liquid Waste
In the past, some of the major sources of water pollution have been landfills, underground storage tanks, and untreated effluent. Under the Clean Water Act, the EPA sets industry-specific discharge limitations for water pollutants. Treatment metho...
