  • 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 ...

  • Oil Analysis for Hydraulic Systems

    Hydraulic systems are used in industrial, mobile and aviation applications to transmit power to operate equipment. They are incredibly efficient, compact, and lightweight relative to a mechanical equivalent. Hydraulic fluids transmit force in the system, and as such are carefully chosen by the system maker. Chemical stability, high flash and fire points, viscosity, and oxidation resistance are ...

  • A novel image processing-based system for turbidity measurement in domestic and industrial wastewater

    Wastewater treatment facilities are continually challenged to meet both environmental regulations and reduce running costs (particularly energy and staffing costs). Improving the efficiency of operational monitoring at wastewater treatment plants (WWTPs) requires the development and implementation of appropriate performance metrics; particularly those that are easily measured, strongly ...

  • Degassing a Liquid for Your Syringe Pump

    Four common methods for degassing samples Methods for Degassing Liquid All solutions equilibrated at room temperature and pressure will contain dissolved gases. Sample degassing is the process of removing these dissolved gases from solution. Removal of these gases may be necessary because the gases may escape from solution and form air bubbles in your syringe, ...

  • Measurement of trace metals in ambient air: Validation of a rapid technique with gold standard ICP-AES

    Trace metals are found at low concentration in the ambient environment and are associated with adverse health effects. The gold standard metal measurement is Inductively Coupled Plasma Atomic Emission Spectroscopy (ICP-AES); however, sample preparation is laborious and expensive. The Xact 625 metals monitor uses non-destructive X-ray fluorescence technology. A built-in sample collection ...

  • In-House Oil Analysis Lab Saves Gold Mine Millions in Downtime, Repair and Replacement Costs

    A low-grade surface mining operation depends upon huge and expensive equipment such as Hitachi 5500 shovels and Caterpillar 793 haul trucks. Oil analysis is essential to identify problems so they can be corrected before they cause equipment to go down for major repairs. In the past, a multinational mining firm sent samples to an outside lab for analysis but the cost of this approach limited the ...

  • Extended CSO control storage: what could possibly go wrong?

    The Thames Tideway Tunnel (TTT), is one of the main components of the London Tideway Improvements Programme, designed to capture combined sewer overflows (CSOs) which currently discharge untreated combined sewage into the tidal river Thames. CSO discharges would be stored in the tunnel until there is capacity at Beckton sewage treatment works (STW), to accept, for treatment, pumped sewage from ...

  • Large City Fleet Saves $2M Using Oil Analysis to Extend Oil Drain Intervals - Case study

    Condition-based maintenance saves time and money and increases productivity A large municipality in the northwestern United States operates over 1.700 vehicles and over 3.000 pieces of motorized equipment ranging from riding lawn mowers to bulldozers Oil changes constitute a major expense. For example, the 500 heavy duty trucks in its fleet previously had their oil changed every 2,500 miles ...

  • Reservoir Management - Online Oil-In-Water Monitor - Case Study

    Background Older generation online oil-in-water (OiW) monitors may suffer from fouling of optics due to scales, soaps, emulsions, sludge, etc., resulting in inaccurate (usually low) concentrations. New generation OiW monitors: Yield more accurate O  iW concentrations Improve accuracy of the OiW measurements, allowing operators to optimize water ...

  • Application of Lab-on-a-chip Technology in Water Analysis

    The Important of Water Analysis Water analysis is essential to ensure its quality or to detect pollutants that should be removed by water treatment. However, water quality does not mean making the water suitable for human consumption; it depends on its end use. For example, completely different quality standards are applied in case of industrial water compared to those ...

  • Four-way Sanitary Ball Valve Overview

    A ball valve is a form of quarter-turn valve that uses a hollow, perforated and pivoting ball to control flow through it. It is open when the bullet hole is aligned with the flow and closed when it is rotated 90 degrees by the valve handle. The handle is flat when open and perpendicular to it when open, which facilitates visual confirmation of the condition of the ...

  • CASE STUDY - Setup and calibration of a three-dimensional numerical multiphase model for design of in-situ remediation of jet fuel with surfactant

    BACKGROUND Storage and pumping of jet-fuel have caused a severe contamination of soil and groundwater at a military facility in Denmark. The contamination was detected in 2001. The Danish Defence has conducted 3 a series of investigations and set up a skimmer system, that has recovered approximately 25 m of jetfuel. In 2005, the recovery stopped, and the remaining jet-fuel is trapped as a ...

  • Oil Analysis Helps Water Plant Cut Annual Maintenance - Case study

    The city of Chandler (Ariz.) Municipal Utilities Department (MUD) employs coagulation, sedimentation, active flow control and filtration to produce 60 million gal per day (mgd) of water at its surface water treatment plant. In addition, the system includes 27 wells and 21 booster stations controlled by SCADA. Water distribution is provided through more than 1,200 miles of water main, in excess of ...

  • Silver Membranes in Monitoring Respirable Crystalline Silica

    Crystalline silica, most commonly found in the form of quartz, is a basic component of the earth; it’s found in soil, sand granite, and other minerals. During many industrial processes, crystalline silica is released as particles that are 100 times smaller than beach sand.1 Due to their size, these mineral particles cannot easily be cleared by human lungs. Instead, they persist in the ...

  • CombiFlash Gradient Methods

    Abstract Purifying compounds require two processes: the actual purification and drying the sample afterwards. Several gradient methods were evaluated on a reaction mixture to evaluate run time and number of fractions to collect the desired compound. Reducing the volume of fractions is important to reduce the time required to dry the purified material. On large runs, drying time may be ...
