  • Surface Water Monitoring - Case Study

    Safe operation of a Water Treatment Plant (WTP) requires careful monitoring of the water supply influent to the plant, as a guard for any substances entering the treatment works that could negatively impact treated water quality in the distribution system. One aspect of water quality that has recently garnered more attention from authorities and utilities is Natural Organic Matter (NOM), which ...

  • Large contribution of water-insoluble secondary organic aerosols in the region of Paris (France) during wintertime

    Near real-time measurements of carbonaceous aerosols were performed in fine aerosols for a 10-day period during winter at a suburban site of Paris (France). These measurements were performed using an OCEC Sunset Field instrument for elemental carbon (EC) and organic carbon (OC) ; a Particle-Into-Liquid- ampler coupled with a Total Organic Carbon (PILS-TOC) instrument for water-soluble OC ...

  • Train derailment prompts contaminated land investigation - Case study

    On March 30th 2015 a long freight train, transporting a variety of goods including lumber and chemicals, wound its way through the state of Mississippi. At around 5pm, part of the train failed to negotiate a curved portion of the track in a rural area near Minter City, resulting in the derailment of nine railcars, one of which leaked chemicals onto agricultural farmland and woodlands. Emergency ...

  • Food & Beverage Industry: Soft Drink - Case Study

    The peCOD (photoelectric Chemical Oxygen Demand) method for COD analysis is well suited to the soft drink industry as it provides plant operators with quick and reliable COD results important for process monitoring and control. Continuous COD monitoring of wastewater can protect production plants by ensuring COD discharge levels meet the acceptable limits, and by detecting product leakage. It can ...

  • Comply with Highly Regulated Oil in Water Measurements Using Portable Infrared Analyzers

    The Petroleum Industry – both offshore and onshore -- has regulations that limit the amount of oil in discharged water.  Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on drilling platforms for over 45 years for a number of reasons. On oil rigs where real estate is at a premium, infrared analyzers such as the Wilks InfraCal TOG/TPH ...

  • Oil in frac water testing

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well. Whether the water is going to be taken off site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the wa-ter. Waiting for remote laboratory results can take several days to a week. The InfraCal TOG/TPH ...

  • Oil Water Separator Maintenance

    Oil water separators (OWS) can be co$tly to maintain, $20,000 or more on average per cleaning and if not properly managed, can be very expensive conduits of pollution. Have you taken steps to minimize the effects and consequences on your operating co$t? When was your facility’s last OWS maintenance ...

  • Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer

    Salt Water Disposal (SWD) well operators often dispose a substantial volume of oil inadvertently when injecting salt water, thereby losing the opportunity to sell the oil on the market and potentially reducing the ability to inject water in the well. Injection facilities are typically operated with minimal instrumentation or system optimization, which means the operators don't know how much, or ...

  • Solvent-free oil-in-water analysis

    Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

  • Portable Infrared Analyzers Provide On-Site Measurement of Oil and Grease Levels in Hydraulic Fracturing Water

    The amount of water used in and produced by hydraulic fracturing of shale gas wells is in the millions of gallons per well.  Whether the water is going to be taken off-site for disposal or reused for re-injection, the flowback or produced water needs pretreatment to remove any residual oil from the water.  Waiting for remote laboratory results to determine the oil level can take several ...

  • Research Institute uses GE InnovOx TOC analyzer to evaluate hydraulic fracturing and oil exploration produced water

    Background The Global Petroleum Research Institute (GPRI) at Texas A&M University-College Station regularly conducts laboratory research studies on various oil and gas produced wastewaters with varying sample matrices. The GPRI tests samples at different shale and oil producing formations using a mobile laboratory, which houses a pilot-scale treatment system for identifying the ...

  • Quantifying the concentration of crude oil microdroplets in oil–water preparations

    Dissolved constituents of crude oil, particularly polycyclic aromatic hydrocarbons (PAHs), can contribute substantially to the toxicity of aquatic organisms. Measured aqueous concentrations of high–molecular weight PAHs (e.g., chrysenes, benzo[a]pyrene) as well as long‐chain aliphatic hydrocarbons can exceed the theoretical solubility of these sparingly soluble compounds. This is attributed to ...

  • 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 ...

  • 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 ...

  • Emulsion-Breaking Techniques for Accurate Oil in Water Measurements

    A White Paper discusses emulsion-breaking techniques for ensuring accurate oil in water measurements. Certain water samples, such as those containing detergent, may form an emulsion when oil in water extraction into a solvent is done. In order to ensure an accurate measurement, the emulsion must be broken. Six techniques are described that can be used for reducing an emulsion ...

  • Emulsion breakingtechniques for oil in water solvent extractions

    Certain types of samples, such as those containing detergent, may form emulsions when doing an oil in water extraction into a solvent. The boundary between the solvent and the sample will have an emulsion layer that lias a cloudy or milky appearance as shown in tlris photo. According to U.S. EPA Method 1664, "if the emulsion is greater than one-third the volume of the solvent layer. Hie ...

  • Water repellency in oil contaminated sandy and clayey soils

    Two sites from a humid tropical environment were studied with respect to soil water repellency caused by hydrocarbon contamination. Samples were analyzed for water repellency (molarity ethanol droplet method), total petroleum hydrocarbons, acute toxicity (Microtox) and field capacity. At both sites, water absorption times were ...

  • TOC analyzer for airports

    During winter, de-icing processes at airports necessitate storm water and de-icing water management. Especially due to adhesive (sticky) substances, strongly fluctuating concentrations and a lot of chemicals, the monitoring systems itself must be tailor-made to fight this water analysis challenge. LAR 's ...

  • Analyzing the potential of community water systems: the case of AguaClara

    Successful maintenance of water provision has as much to do with the ongoing governance of these systems as the technology that goes into building them. This governance generally occurs at the community level. Most water systems are small and located in areas where there is generally not the profitability necessary to entice private investment. Understanding how community management can improve ...
