  • Chemical Engineering Magazine: Odor Issues and Solutions for Wastewater Treatment

    Today, there has been a dramatic increase in the number of industrial operations that are located within or near small towns and even large cities. When local residents constantly smell these industrial processes – particularly from wastewater treatment — unhappy neighborhoods are generally the result. In addition, many wastewater facilities can no longer produce odors without facing ...

  • Environmental analysis of management systems for organic waste

    Organic waste is generally easily degradable and has a high nutrient content. Thus the risk is large that the handling of such material will generate emissions that affect the environment. New systems have been introduced for managing organic waste fractions from households and industries. These systems are based on source separation and biological treatment, e.g. composting and anaerobic ...

  • Performance analysis of the different Organic Rankine Cycles (ORCs) using dry fluids

    This paper presents the first and second laws of thermodynamics analysis for organic Rankine cycles (ORCs), using dry organic fluids as the working fluids. The dry organic fluids for this study were R227ea, RC318, R236fa, Isobutane, R600a, R245fa, HFE7000, R123 and R113. Effects of the operating parameters such as turbine inlet temperature and pressure on the thermal efficiency, exergy ...

  • Hydrologic signature analysis of select organic hydric soil indicators in northeastern Florida

    The magnitude, duration, and return intervals of surface water flooding and dewatering of the landward extent of the hydric soil indicators muck (LM), histic epipedon (LHE), and Histosol (LH) were quantitatively defined, providing a better understanding of the hydrologic conditions maintaining these hydric soil indicators. Land surface elevations were determined for the LM, LHE, and LH at 16 ...

  • Analysis of efficacy of UVGI Inactivation of Airborne Organisms Using Eulerian and Lagrangian approaches

    Abstract Ultraviolet germicidal irradiation (UVGI) is increasingly used in health care facilities to kill airborne bacteria and control the spread of airborne infection among occupants. The most widely used form of UVGI is the passive upper-room lamps that generate a horizontal layer irradiance field above the occupied zone. In this study, the efficacy of killing airborne bacteria by ...

  • Analysis of Organic plating Bath Additives and Chemicals by Isocratic HPLC

    In today’s world, over 75% of all metal surfaces on manufactured metal “items” have some sort of plated finish on them. From highchromium steel car bumpers to zinc diecast toys to Silver-contact electronic components. While the primary composition of these plating baths are inorganic (the metals and salts that are used to make up the desired metal finish), almost all types of plating baths; from ...

  • Database analysis of US state regulatory guidance for organic surface soil contamination

    This manuscript describes a database of US state regulatory guidance values assembled to examine the guidance applied to the most commonly regulated surface soil contaminants. Guidance values were identified for 994 different contaminants, but there is considerable variability in the number of contaminants regulated by each state and in the values applied to contaminants. Guidance values for the ...

  • Electromagnetically vibrated Solid-Phase Microextraction for the analysis of organic compounds

    A newly developed electromagnetically vibrated Solid-Phase Microextraction (SPME) device for extracting 1, 4-dichlorobenzene and toluene from aqueous matrices was evaluated in terms of sorption equilibrium time, precision, and detection level relative to three other more conventional extraction techniques involving SPME, viz., static, magnetic stirring, and fibre insertion/retraction. ...

  • Regional Taiwan rainfall frequency analysis using principal component analysis, self-organizing maps and L-moments

    The objective of this paper is to propose an approach, which consists of principal component analysis (PCA), self-organizing maps (SOM) and the L-moment method, for improving estimation of desired rainfall quantiles of ungauged sites. Firstly, PCA is applied to obtain the principal components. Then SOM is applied to group the rain gauges into specific clusters and the number of clusters can be ...

  • Organics in boiler water condensate

    With the wide use of high efficiency boilers and current high-pressure boilers in industry today limiting condensate analysis to the more traditional parameters can result in very expensive repairs. Condensate return should be the highest quality least expensive water that most systems can generate. Boiler operators do not want to lose this or have it contaminated. Condensate return analysis has ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Measuring total organic carbon in wastewater

    The continuous TOC analysis of industrial waste water is known to be problematic especially, when the TOC analyser is used as a spill monitor for heavily polluted waste water containing a high-load of particles. Thus, most operators require analysers that enable accurate TOC (total organic carbon) measurements. But do they really get those? Common analysers suffer from clogging and blockages due ...

  • How Total Organic Carbon (TOC) analysis relates to disinfection byproducts (DBPs) such as trihalomethanes (THMs) and the corresponding Canadian guidelines

    Municipalities throughout Canada are challenged to balance the risks presented by microbial pathogens and by-products from the disinfectant used to destroy these microbes. The byproducts, called Disinfection Byproducts (DBPs), form from the interaction of the naturally occurring organic matter (NOM) in a treatment plant’s source water and its disinfection process. NOM is typically measured as ...
