  • Syringe Sampling for Counting Particles in Fluids

    Abstract A syringe sampler represents the simplest delivery system for precisely delivering a sample to the particle counter. The precision motion of the syringe drive produces a steady flow of fluid that is free of pulsations that are typical of most pumps suitable for chemical delivery. An overview of the syringe sampling system is ...

  • Test & treat - treating hydrostatic test water

    A pipeline company in Iowa conducted a hydrostatic test of its pipeline, producing 39,000 barrels of fluid for treatment. The hydrostatic test water was to be discharged in accordance with a National Pollutant Discharge Elimination System (NPDES) permit. The permit required that discharge of the treated test water could not exceed a period of 14 days from the date the test was conducted. Fluid ...

  • Submersible Pumps - The Airlift Principle

    The Air lift principle has been around for many years. In fact it was first conceived in 1797 by the German engineer Carl Emanuel Löscher and is one of the most simple and basic ways to pump water and other fluids. Not only is the principle simple, there is not much to go wrong. Airlift in its simplest form had its limitations, but recent developments have enabled far more ...

  • Principal Noise Pollution Control

    Sources of noise in industrial machinery and processes are : Rotors, Gears, Turbulent Fluid Flow, Impact Processes, Electrical Machines, Internal Combustion Engines, Pneumatic Equipment, Crushing, Blasting, Pumps and Compressors. The most desirable method of controlling a noise pollution is to minimize the noise at the source. This generally means modifying existing equipment and structures or ...

  • Common Treatment Train for Nonhalogenated VOCs

    A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for nonhalogenated VOCs is illustrated below. A soil vapor extraction system is used to pull VOC vapor from the contaminated soil. An air sparging system delivers air below the water table to enhance bioremediation. After passing through a liquid/vapor separator, the VOC ...

  • 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 ...

  • Qdos metering pumps usurp diaphragm models

    The revolutionary new Qdos 30 metering pump from Watson-Marlow Fluid Technology Group is proving a resounding success in Barrie, Canada. Located in southern Ontario on the western shore of Lake Simcoe, Barrie is a modestly sized city (135,000 residents) but one with a track record for quality when it comes to its potable water supply. Here, the Water Operations Branch of the Corporation of the ...

  • Utility optimisation for distillation columns via simulated annealing

    Distillation remains the most widely used separation technique in the petrochemical and chemical process industries for the separation of fluid mixtures. Distillation is an energy-intensive process for which heat pumping may be well-suited. The distillation column problem is a two stream problem (distillate and bottom streams) for which no integration is possible without heat pumping. The only ...

  • Avoiding Pump Problems

    As with any pump system, there are some basic components involved — a driver, the impeller/pump and the transmission. The basic difference is that instead of a flexible coupling or gear train, the transmission is a hydraulic system. The hydraulic system is composed of a hydraulic pump, hydraulic motor, supply tank, filtration method, cooling method and transfer ...

  • Experimental investigation of power-assisted steering pump noise for housing material change from cast iron to aluminium

    Noise and vibration have an important influence on a customer's perception of vehicle quality. In this research, the major power-assisted steering pump noise propagation mechanism is determined. Noise and vibration comparison tests have been completed for subjectively good and bad cast-iron housed pumps, as well as for an aluminium housed pump. Decoupling tests for the steering rack disconnected ...

  • Peristaltic Pumps excel in Anaerobic Digestion & Biogas applications

    Biogas is a natural gas also known as biofuel or biomass and is produced by breaking down organic material such as household waste, manure and crops grown specifically for biofuel with temperature-sensitive microbes and capturing the by-products. In practice, it is difficult to find a pumping system for this application. Why? The pumps needs to handle fluid media as well as gas parts ...

  • Computation Fluid Dynamic Modeling of a Proposed Influent Pump Station

    Traditionally pump intake hydraulics have been investigated using scale physical hydraulic models. Computational fluid dynamics (CFD) is a rapidly improving technology that in some cases can be used as a cost or time effective alternative to traditional physical model methods for evaluation of pump intake hydraulics. This paper presents a case study on the use of CFD modeling to re-evaluate and ...

  • Simulation of seawater intrusion in the Nile Delta aquifer under the conditions of climate change

    The problem of seawater intrusion is encountered in almost all coastal aquifers. Because of its higher density, the seawater migrates inland into freshwater aquifers even without any pumping activities. Excessive pumping of groundwater would accelerate seawater intrusion. Climate change and sea level rise represent critical parameters affecting the rate and degree of seawater intrusion. In ...
