  • How viscosity affects flow rates?

    Choose the Best Peristaltic Pump for the Job! A frequent question regarding peristaltic pumps is how viscosity affects flow rate. The short answer is; as viscosity increases, flow rates decrease. That being said, there are various factors which need to be understood when considering a peristaltic pump for any application that requires pumping viscous fluids. The physical ...

  • E-Guide Measuring Oil Viscosity

    The most important physical property of a lubricating oil is viscosity. Viscosity determines the load carrying ability of the oil as well as how easily it circulates. The correct balance between high viscosity for load carrying and low viscosity for ease of circulation must be considered for any lubricant and its application. ...

  • Effect of substrate feeding on viscosity evolution of anaerobic granular sludges

    This work aims to describe the effect of the feeding regime of anaerobic activity tests on the limit viscosity (μlim) evolution of the granules. Batch experiments were performed with 3 different sources of substrate: acetate, peptone, and glucose. Despite, the substrate origin was shown to affect the μlim evolution of granules, no clear relationship was found between the ...

  • Improvement of an Industrial Wastewater Treatment System at a Former Viscose Rayon Plant – Results From Two-Stage Biological Leachate Treatability Testing

    Leachate is currently being pumped from three surface impoundments filled with waste material from the production of viscose rayon at the former Avtex Fibers plant. The primary objective of this study was to optimize a two-stage biological treatment process that has the potential to effectively treat a wastewater stream containing high levels of reduced sulfur compounds while also removing ...

  • Field Performance Testing for Pipeline Pumps

    Significant energy savings can be achieved by optimizing pump operating efficiency. Measuring the exact pump performance with crude oil under realistic conditions in the field is the first step towards improving the pump efficiency in the future. About 20 billion barrels of crude oil were transported through pipelines in 2015. Around the world, there are over one million kilometers of ...

  • Strain-Rate Influence on the Interpretation of Plate Bearing Tests

    The effect of the rate of load application (or settlement application) during a plate bearing test, on the load-settlement relationships is examined. A series of plate bearing tests on clay demonstrated that when the loading rate increases the bearing capacity and the stiffness also increase. To quantify this increase, an exponential foundation model was proposed, which considers the clay as a ...

  • Chemical and Biological Treatability Testing of an Industrial Leachate

    Remediation efforts are ongoing at the Avtex Fibers Superfund Site in Front Royal, Virginia. As part of the future remediation of several surface impoundments used for viscose waste disposal during plant operation, it may be necessary to extract contaminated leachate and groundwater for ex-situ treatment and discharge to the Shenandoah River. This waste stream contains high concentrations of ...

  • Testing of Oil Recovery Skimmers in Ice at Ohmsett - The National Oil Spill Response Research & Renewable Energy Test Facility

    Abstract The mechanical recovery of oil in ice-infested water presents unique and difficult clean-up challenges. Ice can impede the movement of spilled oil making it less available for removal by the active components of oil recovery skimmers. Ice and slush that is recovered with oil can jam the skimmer, pump inlets and hoses and can provide an environment for enhanced emulsion formation. ...

  • Frequency Response of Diaphragm Pore Pressure Transducers in Dynamic Centrifuge Model Tests

    A theoretical relation for estimating the frequency response of diaphragm pore pressure transducers is derived by considering the interaction between the diaphragm, porous cap, air, and pore fluid inside the transducer. Using this relation, the frequency response of a pore pressure transducer under several centrifuge modeling environments is studied. The results indicate that the viscous drag ...

  • Pilot Testing Microfilters and Cloth-Media Filters for Lake Augmentation

    ABSTRACTMicrofiltration and cloth-media filtration were pilot tested for plant expansion and water supply augmentation purposes. The performance of the pilot units was assessed by evaluating key influent and effluent data, including suspended solids, turbidity, total phosphorous, hydraulic loading rate, flux, and chemical addition. Results showed that one of the cloth-media filters, and both of ...

  • Portable IR analyzers: the ideal measurement solution for biofuels blend quality and wastewater testing

    Two challenges facing the biofuels industry involve compliance with blend quality standards and wastewater regulations. According to a study done by the National Renewable Energy Laboratory, 1 the chief problem found with biodiesel blends was inaccurate blend ratios. Retail customers and fleet managers do not typically worry about whether the blend ratio is correct until a problem occurs. For ...

  • Use of the newly developed ASTM Standard F 2709 (Standard Test Method for determining nameplate recovery rate of stationary oil skimmer systems)

    Abstract The American Society of Testing and Materials (ASTM) subcommittee on skimmers recently adopted a standard methodology for measuring skimmer performance, F 2709 - . Standard Test Method for Determining Nameplate Recovery Rate of Stationary Oil Skimmer Systems. Current industry practice allows manufacturers to label skimmers with a nameplate capacity based solely on the ...

  • The performance and emission characteristics of a diesel engine using preheated Kusum oil and Kusum diesel blend

    Rapidly depleting conventional petroleum resources have prompted research for alternative fuels. Among various possible options for internal combustion engines, fuels derived from triglycerides (vegetable oils/animal fats) are a promising substitute for diesel fuel. Vegetable oils pose some detrimental characteristics like high viscosity and low volatility compared to diesel fuel. In the present ...

  • Parametric study of biodiesel quality and yield using a bench-top processor

    Biodiesel is a renewable liquid fuel alternative to petrodiesel. It is produced by the transesterification of vegetable oil and alcohol in the presence of a catalyst. A 1.5 L bench-top biodiesel processor was constructed to study the effect of feedstock and operating conditions on the conversion and the biodiesel quality. Biodiesel was produced from several oil feedstocks using methanol and ...

  • Mop Water Treatability

    The samples were tested at our facility on Thursday, March 20, 2003. Visually the samples were a homogeneous mixture of mop water, oil, and metals. The initial pH was 10.5 and the conductivity was 7,500 μS.The sample was ozonated at a setting of 35% of capacity (35% of 3.9 gm/hour) or 1.37 gm/hour in the stabilization column for 12 hours. There appeared to be very little separation of oils ...

  • Viscous Pumping in Focus

    The performance of a pump is influenced when it handles viscous fluids such as crude oil. For the configuration and design of pumps, this is key. In the industry, pump performance curves are developed by testing with water at temperatures around 25°C and corrected to a specific gravity of one. Engineers use this standard so that they have comparable measurement values around the ...
