  • Fluid waste management and disposal practices

    Prior to the early 80s and the introduction of AIDS into our society, infection control practices were designed almost exclusively to protect the patient from developing a nosocomial infection an infection acquired after admission to the hospital. Protocols were focused on protecting the patient, with little or no emphasis on the health care workers potential to become infected. Hepatitis B has ...

  • Modelling the motion of an internal solitary wave over a bottom ridge in a stratified fluid

    A series of laboratory experiments has been carried out to investigate the passage of an internal solitary wave of depression over a bottom ridge, in a two-layer fluid system for which the upper and lower layer is linearly-stratified and homogeneous respectively. Density, velocity and vorticity fields induced by the wave propagation over the ridge have been measured simultaneously at three ...

  • Fearless flow back - treating completion fluids & acid flow backs

    An oil company completed a well and CETCO Oilfield Services was there to treat the flow back fluids. During the flow back, it was necessary for the oil company to continue normal drilling operations. Deck space on the structure was at a premium for the oil company, who simultaneously continued drilling while flow back fluids were being treated. CETCO Oilfield Services’ proven technology and ...

  • In Situ Rheological Monitoring of Viscous Non-Newtonian Fluids using a Helical Ribbon Agitator

    Mechanically degraded food fluids were modelled as Power law fluids in a pilot scale (42 l) helical ribbon agitation vessel. Effective rheological representative flow curves determined from speed/torque data proved comparable to off-line laboratory rheometer measured data. Modelling effective viscosity as a Power law function gave effective consistency coefficient Keff which correlated strongly ...

  • What Features Do You Need In Your Mobile Or Modular Laboratory?

    Today’s need for laboratories crosses many industries in a variety of ways.  This is driven by numerous factors, but most notably by regulatory compliance requirements and the need to increase the efficiency of operations.  Whether the need is for a mining operation’s compliance covering storm water quality or an oil/gas company running geochemical operations on well fluids ...

  • Minnesota makeover - treating hydrostatic test water

    A pipeline company in Minnesota conducted a hydrostatic test of its pipeline, producing approximately 320,000 barrels of fluid for treatment. Fluid was pumped from the pipeline into three storage tanks located at the pipeline’s tank farm. Fluid was then pumped from the storage tanks directly to CETCO Oilfield Services onsite equipment. On average, CETCO Oilfield Services treated the fluid at a ...

  • Characterisation of water–oil drainage process through a reservoir rock sample by digital core analysis

    Oil–water relative permeability and capillary pressure of a water–wet digital core are computed using the finite–volume/volume of fluid method and mimicking traditional laboratory steady–state experiments carried out on a water saturated sample. Commercial software is used for immiscible multiphase fluid flow simulations, carried out on a low–cost multicore workstation, and the pore–scale data ...

  • Application notes - viscosity measurement

    Most laboratory viscometers employ the well-known principle of rotational viscometers to measure viscosity by sensing the torque required to rotate a spindle at a constant speed while it is immersed in the sample fluid. This is because the torque, generally measured using the reaction torque on the motor, is proportional to the viscous drag on the immersed spindle and thus the viscosity of the ...

  • Intrusion and leakage in drinking systems induced by pressure variation

    Pathogen intrusion is a phenomenon that can cause a serious pollution problem in drinking systems. The paper describes the entry of external fluids through pipe defects caused by a pressure drop. This situation is especially important during hydraulic pressure variations. Pressure variations that can cause intrusion are analyzed in this paper. Three cases of pressure transients are modeled with ...

  • Investigation of the performance of single and multi–drop hydraulic structures

    In this paper, the work is divided into two parts. First, the hydraulic performance of single and multi–drop structures is investigated and compared using two approaches. In the first approach, the empirical equations found in the literature are summarised and reanalysed to compare the dissipation of energy of single drop and multi–drop structures. The demarcation condition at which multi–drop ...

  • Biological Control in Cooling Towers Treated with Pulsed-Power Systems

    Biological control is the foundation of cooling tower water treatment. Biofilm can directly cause corrosion problems (microbial induced corrosion, MIC), pathogen concerns (Legionella), increased pump pressure, heat-transfer problems, dermatological effects, and malodors. With the increasing restrictions being imposed at the federal and state level regarding chemical use in cooling towers (CAA, ...

  • Hydraulic conductivity of compacted clay liners permeated with inorganic salt solutions

    Due to their low permeability, geosynthetic clay liners (GCLs) and compacted clay liners (CCLs) are the main materials used in waste disposal landfills. The hydraulic conductivity of GCLs and CCLs is closely related to the chemistry of the permeant fluid. In this study, the effect on the hydraulic conductivity of clays of five different inorganic salt solutions as permeant fluid was ...

  • CFD modelling of flow field and particle tracking in a hydrodynamic stormwater separator

    The best management practices (BMPs) for control of urban stormwater pollution are evaluated to remove solid particles containing various pollutants. Currently, most storm runoff treatment devices using primary pollutant removal mechanism are applied to storm water since most pollutants in runoff are associated with the solid particulates. A hydrodynamic separator is a storm water treatment ...

  • Simulation of overflow nappe impingement jets

    Rectangular jets constitute one of the energy dissipation methods in the overtopping of dams. The high turbulence and aeration phenomena that appear in falling jets and dissipation basins make it difficult to carry out studies based only on classical methodologies. There are studies modelling spillways with computational fluid dynamics which produces accurate results. However, the study of ...

  • Geometric issues in reverse osmosis: numerical simulation and experimentation

    This investigation is a synergistic combination of laboratory experimentation and numerical simulation to quantify the practical impact of geometric imperfections in the flow channels of a reverse osmosis (RO) system. To this end, carefully executed experiments are performed to quantify the fluid flow in a system containing feed spacers which are embedded in the RO membrane. In a complementary ...

  • Investigation of the shape change of bio-flocs and its influence on mass transport using particle image velocimetry

    In this laboratory study, an advanced flow visualization technique – particle image velocimetry (PIV) – was employed to investigate the change of shape of activated sludge flocs in water and its influence on the material transport characteristics of the flocs. The continuous shape change of the bio-flocs that occurred within a very short period of time could be captured by the PIV ...
