  • Over the River and Through the Plants to Richland Chambers We Go

    ABSTRACTIn order to meet future water supply requirements, Tarrant Regional Water District is pursuing several options including diverting Trinity River water into two of the District’s reservoirs located downstream of the Dallas-Fort Worth Metroplex. The District’s approach to augment the water supply with reclaimed water involves a multiple-barrier approach including advanced wastewater ...

  • Energy and the environment - A new look by an Old Hand

    I recently received an autographed copy of a new book from a friend that shone new light on an old problem - how to meet the world's energy needs without jeopardizing the environment. The book, entitled Renewable Energies with Energy Storage, was authored by Winston (Win) Stothert.  In it he tackles three very pressing and interconnected environmental problems - climate, energy and water. ...

  • Case study - Engine test cell exhaust: RTO

    Overview A Mid-western outboard engine manufacturer bought a three year-old plant for the production of its marine engines. When finished, the engines are removed from the assembly line and run for quality control. The 25,000 SCFM of exhaust from testing contains volatile organic compounds (VOCs) that require regulatory compliance. Also within this exhaust is a great deal ...

  • Preparation and characterization of nickel‐spiked freshwater sediments for toxicity tests: Toward more environmentally realistic nickel partitioning

    We compared two spiking methods and evaluated nickel (Ni) partitioning during a series of toxicity tests with eight different freshwater sediments having a range of physico‐chemical characteristics. A two‐step spiking approach with immediate pH adjustment by addition of NaOH at a 2:1 molar ratio to the spiked Ni was effective in producing consistent pH and other chemical characteristics across ...

  • Is your Plant as tight as you think? Leak Detector for extremely toxic Gases, a Field Test Report

    Leak detection of commodity gases in chemical plants is a day-to-day practice. The sensor technology available for this application is field proven and reliable. No question about it, existing sensors will do the job. However, in plants manufacturing or handling extremely toxic substances, the picture is different. For example, take phosgene. The existing sensor technology for leak detection ...

  • Screening of volatile organic compounds as a source for indoor pollution

    For a considerable period of time the presence of an increasing number of chemicals has been observed in almost all aspects of human life. This process also affects the living and working environment of man. Human development, including physical and mental health and well-being, depends on to a great degree on the surrounding environment. Considering that an average person spends a significant ...

  • Avoidance of contaminated sediments by an amphipod (Melita plumulosa), a harpacticoid copepod (Nitocra spinipes), and a snail (Phallomedusa solida)

    The distribution of contaminants is seldom homogeneous in aquatic systems. In the present study, the avoidance response of Melita plumulosa, Nitocra spinipes, and Phallomedusa solida when exposed to contaminated sediments was investigated. Test vessels were designed to allow the congruent placement of two sediments and assessment of the movement of organisms between the sediments. When exposed to ...

  • CDS-5: A Mayo Clinic and Thermotron Collaboration case study

    Cytogenetic testing is used for the diagnosis of many genetic disorders including congenital (prenatal and adult) and hematologic/oncologic disorders. Processing of these tests used to be labor-intensive with unpredictable test data. That’s why the Cytogenetic Laboratory at Mayo Clinic and Thermotron joined forces to increase the efficiency of cytogenetic test processing with the invention ...

  • Survival of E. coli O157:H12 in creek sediments after inoculation and re–inoculation

    This work tested the hypothesis that E. coli survival after streambed sediment inoculation does not differ significantly from survival in the same sediment after re–inoculation. The E. coli O157:H12 survived in two sediments with markedly different particle size distributions and organic matter contents in one–month–long experiments in flow–through chambers at 14°C and 23°C. The inactivation ...

  • Ethylene removal in domestic refrigerators

    Ethylene is a plant hormone produced naturally by fruit and other plant tissues. It is known as the ripening hormone because it regulates the series of processes associated with the ripening and senescence of fruit. Ethylene removal from the environment, both in storage chambers and transport containers, where it is stored in the form of gas, is a widespread practice designed to provide a ...

  • Case study - ETO sterilizer abatement

    OVERVIEW Product sterilization companies are generally required to utilize a pollution control device for treatment of exhaust gases from their aeration room and sterilization chambers.  In the United States, they need to be in compliance with NESHAP (National Emission Standards for Hazardous Air Pollutants) regulations that dictate a 99% destruction efficiency of EtO (Ethylene ...

  • Transient adhesion mediated by ligand–receptor interaction on surfaces of variable nanotopography

    Surface microtopography and nanotopography have been shown to influence cell adhesion and function, including proliferation and differentiation, leading both to fundamental questions and practical applications in the field of biomaterials and nanomedicine. However, the mechanisms of how cells sense topography remain obscure. In this study, we measured directly the effect of nanotopography on the ...

  • Towards the simulation of size-resolved aerosol over Europe: model and observations

    Knowledge of the number density and size distribution of atmospheric aerosols in the submicron size range is essential for estimation of the aerosol radiative effects and the health impact of particles. Ultrafine particles (UFP), i.e. particles with diameters <100 nm, have received increased attention in recent years with improved possibilities of measuring them. UFP originate from nucleation, ...
