  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • 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 ...

  • How Do You Know If An Industrial Facility Needs a Wastewater Treatment System?

    Not properly treating wastewater can potentially harm the environment, human health, and a facility’s process or products (especially if the wastewater is being reused). It can also cause a company to incur heavy fines and possible legal action if wastewater is being improperly discharged into a POTW (publicly owned treatment works) or to the environment (usually under a National Pollutant ...

  • The Phase 1 Environmental Assessment

    In today’s world where every property is subject to potential environmental risks a Phase 1 Environmental Site Assessment or ESA is an appropriate action to take. An ESA can help determine if the property has been contaminated by previous or current activities. The ESA can help protect the purchaser of a property from environmental risks prior to the closing on a property.  Lenders ...

  • The climb to the top

    Back in the late 1980’s when market drivers created the cost-effective option of using above-ground circular tanks for industrial activated sludge processes, there were some early valuable lessons for both aeration equipment manufacturers and plant operators. As production plants got away from in-ground basins, one of the more simple innate operational checks became more challenging; ...

  • Comparing nonreinforced and internally reinforced GCL

    Water is one of the most destructive forces on the planet, eroding everything from continents to human-made wonders. Water is also a vector by which contaminants spread from landfills and other waste reservoirs. Therefore, creating effective water seals has been a top concern in construction. For many years, factory-fabricated clay products have been the barrier of choice against water and other ...

  • What are the best companies for Zero Liquid Discharge Equipment and Technology?

    With an increasing push for environmental protection, many industrial facilities and effluent regulators are making decisions that lessen their impact on the environment and human health. Changes and implementations are constantly being discussed and met both nationally and internationally to change the way industrial facilities discharge waste, and it is important to know which companies are the ...

  • 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 ...

  • 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 ...

  • Techniques for Oil in Water Analysis

    The people responsible for conducting oil in water measurements understand that the measurement can be quite challenging. Wastewater from different sources can contain many different types of hydrocarbons, each with different chemical make-ups. On top of the lack of chemical uniformity in different oils, there has been a ...

  • Oil Water Separation

    An industrial facility imports oily wastes and separated them using a thermal process. The process raises the oil water temperature to 180 degrees F and uses insulated tanks to obtain an oil/water split. The facility had a 3-day workweek processing 100-200K gallons/day and then maintenance of the equipment the rest of the workweek and often weekend(s). The majority of the work was keeping the ...

  • 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 ...

  • Case study - Crude oil in water

    Produced Water Treatment Site: A pilot study was performed to test water samples contaminated with produced water from several oil well production sites in Wyoming for a company that provides mobile water treatment systems that enable oil and gas companies to recycle and reuse flow back water more efficiently. The samples were tested for their gasoline range and extended diesel/oil range ...
