  • Use of cooling tower blow down in ethanol fermentation

    Reducing water consumption in bioethanol production conserves an increasingly scarce natural resource, lowers production costs, and minimizes effluent management issues. The suitability of cooling tower blow down water for reuse in fermentation was investigated as a means to lower water consumption. Extensive chemical characterization of the blow down water revealed low concentrations of toxic ...

  • Tackling the Challenges Created by Water-Energy Nexus

    The energy industry is under tremendous pressure to minimize its carbon and water footprint. Tremendous amounts of water are required for the production of both oil and gas as well as power generation. In addition to the water consumed, there are also significant amounts of wastewater generated by these industries. This makes the energy industry the biggest consumer of water as well as its most ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • Legionnaires is an Air Quality Risk

    The recent Bronx, NY outbreak of Legionnaires infections is a grim reminder of the deadliness of this strain of pneumonia. Like many of the outbreaks, cooling towers caused this one. Twenty have been identified but the search is still going on. Over 120 people were infected and 12 have died. Tragically it affects the most vulnerable people–people with one or more immune system deficiencies. ...

  • Stormwater Solids Reduction for NPDES Permits

    Finally obtaining a National Pollution Discharge Elimination System (NPDES) Permit is often a relief but is by far not the end of the story. Meeting the requirements of that permit often proves to be quite difficult and stiff fines are freely doled out to those who fail to meet regulatory limits. For one Midwest jet propulsion manufacturing facility, the issue of total daily solids discharge ...

  • It’s Time to Rethink Cooling Tower Filtration

    ABSTRACTThe dissipation of ambient or process heat in large HVAC systems, manufacturing facilities, power generation plants, refineries, metal mills and forges, chemical plants and food processors is most often accomplished by cooling towers. These simple structures facilitate the transfer of unwanted energy (heat) from a transport liquid (usually water) to the atmosphere. The bane of cooling ...
