  • Generation of daily naturalized flow at ungaged control points

    The development of daily naturalized flow in the water rights analysis package (WRAP) model at ungaged stations has difficulties because of low daily flow measurement at gaged stations, low available monthly naturalized flow, and budget constraints. This study proposes a procedure for developing daily naturalized flow at ungaged stations. The soil and water assessment tool (SWAT) model was ...

  • Controlling scale in water systems helps prevent legionella

    The Legionella bacterium, Legionella Pneumophila (LP), the fundamental agent of Legionnaire’s Disease, is a water-based organism, which causes infection when inhaled in an aerosol form. Legionnaires' Disease acquired its name in 1976 when an outbreak of pneumonia occurred among persons attending a convention of the American Legion in Philadelphia. Later, the bacterium causing the illness ...

  • Development of a self-rechargeable digital water flow meter

    The objective of this paper is to present the feasibility of a self-rechargeable digital water flow meter (SRDFM) system for water pipes using the latest data processing and wireless communication technologies while causing negligible water pressure drop (head loss). The system uses a Pelton turbine generator to power the electronic circuit, which processes and transmits the signals generated by ...

  • Robust water quality controller for a reverse osmosis desalination system

    This paper presents two-degree-of-freedom (2-DOF) robust loop-shaping control methodology to stabilize a reverse osmosis (RO) desalination system operating under significant uncertainties, external disturbances and measurement noises, and to reduce product water cost. This method has the advantages that no information about the plant uncertainty is required and it can deal with external ...

  • Modeled Flow Duration Variations, Pollutant Discharges, and Costs for Different Stormwater Controls

    ABSTRACTRunoff volume and pollutant discharges increase with development, with associated detrimental receiving water effects. These increases can be partially controlled by installing stormwater control practices, such as wet detention pond at outfalls, using conservation design controls such as grass swales and bioretention devices, and by improved development practices that reduce the amounts ...

  • Microbial Control and Sanitization of Membrane-Based Pure Water Treatment Systems

    Introduction Today's high technology water purification systems are designed to remove many types of impurities. One of the most difficult to deal with is microbiological contamination. Microbial growth in a water system presents two problems: it not only reduces water quality, but if left unattended, the problem can 'grow' to reduce system performance and life. Biofouling can cause a decrease ...


  • All About Low Flow Carpet Cleaning Systems

    Rug cleaners are used for cleaning carpets, mats, rug, upholstery, and other soft surfaces. These are low-powered machines suitable for cleaning soft surfaces. The output pressure and temperature, often the indicators of cleaning power for cleaning equipment, are relatively low for these machines. The output pressure of even the industrial rug cleaners does not exceed 500 psi. Only the most ...

  • Continuous nonlinear model predictive control of a hybrid water system

    Incorporating weather forecasts in the control of land surface water levels requires predictions of the net inflow to the water system. This net inflow is the combined flow of an incoming load (rain, evaporation, etc.) and outgoing pump rates. Because the pump costs are considerable, optimal pump schedules have minimal energy consumption. Model predictive control (MPC) is able to compute, revise ...

  • Online flow measurement

    Background The undershoot weir in Hohensaaten was built in 1913. It has three openings and regulates the discharge from the Oderbruch and from the Finow canal into the Hohensaaten-Friedrichsthaler-waterway. Moreover, it protects parts of the Oderbruch against Oder floods. The weir controls the waterlevels in the Havel-Oder-waterway and in the reach of Niederfinow- Hohensaaten. ...
