  • Sludge Minimization Technologies-Doing More to Get Less

    Sludge minimization technologies have been available for several decades; however recent developments have brought some sludge minimization technologies to the forefront. All of the technologies utilize one or more of three basic approaches to minimize the amount of waste activated sludge produced by an activated sludge process: cell lysis, cyclic oxic environments, and long solids retention ...

  • Field Performance Testing for Pipeline Pumps

    Significant energy savings can be achieved by optimizing pump operating efficiency. Measuring the exact pump performance with crude oil under realistic conditions in the field is the first step towards improving the pump efficiency in the future. About 20 billion barrels of crude oil were transported through pipelines in 2015. Around the world, there are over one million kilometers of ...

  • Evaluation of Tire Derived Rubber Particles for Biofiltration Media

    ABSTRACTCurrently, on average, one tire is discarded in the U.S. for every man woman and child every year. While the reuse market for used tires has increased over the years to approximately 75%, there are still an estimated 2-3 billion used tires stockpiled in the U.S. Finding economical and sustainable end uses for this tire material is an ongoing challenge to environmental engineers and ...

  • Sick-building syndrome and building-related illness

    Significant health problems linked to very poor indoor air qualityIndoor Air Quality (IAQ) deals with the content of interior air that could affect health and comfort of building occupants. The IAQ may be compromised by microbial contaminants (mold, bacteria), chemicals (such as carbon monoxide, radon), allergens, or any mass or energy stressor are more prevalent than anyone could have predicted. ...
