  • Separation

    Introduction: Ex situ separation can be performed by many processes. Gravity separation and sieving/physical separation are two well-developed processes that have long been primary methods for treating municipal wastewaters. Magnetic separation, on the other hand, is a much newer separation process that is still being tested. Gravity Separation Gravity ...

  • A Guide to Oil in Water Monitoring for Environmental Compliance

    Applications for industrial oil in water monitoring can vary greatly. In upstream and midstream oil and gas production applications, monitoring separation efficiencies is key to optimize production rates, preventative maintenance, chemical use, flow, and environmental compliance. Separated water from the oil is called produced water and it must be cleaned of oil before disposal or ...

  • Solvent choices for infrared testing of oil and grease in water

    Water is a very strong absorber in the mi d infrared (I R) regio n where o il is measured. We see the effect of infrared absorbance when a cold bucket of water left in the sun is quite warm by afternoon due to the absorption of infrared energy as heat. When measuring part per million (ppm) oil levels with mid IR, the water absorbs so much of the infrared energy that the signal becomes saturated ...

  • Evaluating Spiral-wound Separator Performance

    Introduction The recent evolution of spiral-wound membrane element (sepralator) design brings an increased need to understand the intricacies of testing, operating and predicting performance of this most popular crossflow membrane design. After over a decade of stagnant development, the last five years have produced several innovations, which diversify and expand the applications as well as ...


  • Factors Affecting Oil in Water Testing Methods

    Various factors need to be considered when comparing methods to measure oil and grease in water.  Whether you are trying to meet effluent limits for an NPDES (National Pollutant Discharge Elimination System) permit, comply with oil and grease limits for the Clean Water Act (CWA), or an industry satisfying a POTW’s (Publically Owned Treatment Works) discharge permit, it is ...

  • In Situ Physical/Chemical Treatment for Ground Water and Leachate

    The main advantage of in situ treatments is that they allow ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ processes, however, generally require longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

  • Whitepaper: Chemical-physical Water Treatment, Filtration and Flocculation

    Introduction In water treatment plants chemical-physical processes play an essential part in the process chain. They are successfully employed in the pre- and post-treatment of waters of different origins, as well as of other process liquids. In this regard the removal of particles by filtration is a central step. Classical filtration processes are used for particles ranging from ...

  • Looking Beyond Chemical Water Treatment Case Study

    When you think of an environmentally friendly company, a steel processing plant does not typically come to mind. However, Stripco Inc. of Mishawaka, IN, a manufacturer of production-ready, cold-rolled steel coils, is the exception. In August of 1995, Stripco made a wise decision that also proved to be cost-effective and environmentally- friendly when they installed a Superior Environmentalist ...

  • Technology for heavy oil and bitumen recovery with low water cut

    The core of the technology resides in the reduction of oil viscosity and the respective production rate increase under the condition of oil layer heating. It is known, for example, that the heating of the layer with heavy oil up to 100°C theoretically leads to a 15 to 20 times production rate increase. The technology works on the principle of controlled automated continuous pumping of highly ...

  • A Citizen`s Guide to Chemical Dehalogenation

    What is chemical dehalogenation? Chemical dehalogenation is a chemical process to remove halogens (usually chlorine) from a chemical contaminant, rendering it less hazardous. Halogens are a class of chemical elements that include chlorine, bromine, iodine, and fluorine. Polychlorinated biphenyls are halogenated compounds that once were used in high voltage electrical transformers because they ...

  • Hazardous chemicals and proper storage solutions

    Many acceptable categorical storage schemes have been proposed and used by laboratories in academic, industrial, government and medical institutions. The common features uniting all these plans is the separation of incompatible materials. The differences in these various storage schemes arises in the number of groups that should be established for segregation purposes. The ten most commonly cited ...

  • Ex Situ Physical/chemical Treatment for Ground Water, Surface Water, and Leachate

    The main advantage of ex situ treatment is that it generally requires shorter time periods, and there is more certainty about the uniformity of treatment because of the ability to monitor and continuously mix the ground water. Ex situ treatment, however, requires pumping of ground water, leading to increased costs and engineering for equipment, possible permitting, and material handling. ...

  • Will your oil in water analysis method match the regulatory method?

    Anyone involved in field analysis of oil in water will continually get the question “Does your equipment match the regulatory method?” While the amount of oil in water is highly regulated -- it can also be a challenging measurement. It is complicated by the fact that oil comes in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the ...
