  • Water Treatment System Types and Their Benefits

    Water is one of the most important utilities in the world. It’s used for bathing, cooking, washing clothes, cleaning dishes, and drinking. If you get your water from the city, you trust your tap water to be clean and healthy. It goes through a treatment plant before it reaches you, so it’s perfectly purified when it reaches you—right? Unfortunately, this isn’t always the ...

  • Leak behaviour in pressurized PVC pipes

    The correct definition of the leak law, i.e. the relationship between the leak outflow, the total head at the leak and other relevant parameters such as the pipe material, can seriously affect the accuracy of the numerical models used for the management of water distribution systems, either if they are used to forecast the leakage reduction by pressure management or to locate and size the leaks ...

  • Deal With The Pressure - Protect piping system components with Pulsation Dampeners

    Metering pumps with operating pressures of up to 150 psig (pounds per square inch gauge) can create unwanted pressure pulsations within a piping system – a real problem in applications such as filling, mixing and spraying that require a combination of a metering pump’s accuracy and a continuous flow. But the issue can often be addressed with Pulsation Dampeners.The Pulsation Dampeners, usually ...

  • Intelligent pressure management reduces water losses and minimizes pipe brakes

    Leaks in water pipes and leaking valves in urban water distribution systems and pipeline networks, mainly in developing and threshold countries, are the reason for water losses of up to 50 percent in relation to the water quantity being produced in the water works. The articele of the 'Industrial Valves 2009' presents an effective pressure management on the basis of an intelligent control ...

  • Characterising the pressure-leakage response of pipe networks using the FAVAD equation

    This study investigated the feasibility of characterising the pressure-leakage response of water distribution systems using the FAVAD (Fixed and Variable Area Discharges) equation, instead of the conventional N1 power equation. The study was based on 300 network models with randomly distributed leaks and 35 networks generated through a sensitivity analysis. It was found that the leakage rate ...

  • Custom Pressurized Plastic Pipe Disposal Solution - Case Study

    Problem A large petro chemical company asked Waste Control Systems to solve a problem of pressurized plastic pipe after it had been tested for bursting strength. The QA test consisted of taking an eighteen inch section of pipe and welding caps on each end. One cap was solid and the other consisted of a fitting to allow air to be pumped into the section of pipe. A check valve was ...

  • A multi-step genetic algorithm model for ensuring cost-effectiveness and adequate water pressure in a trunk/limb mains pipe system

    A water distribution network is the most expensive component of a water supply system; consequently, the overall planning, installation, and rehabilitation processes should be implemented accurately and carefully. The main issue that developing countries are facing is how to optimize the distribution network to meet increasing water demand. To tackle the issue, this paper proposes a new concept ...

  • Quadratic approximations for pipe friction

    This paper develops quadratic approximations to the classical models of Darcy–Weisbach and Hazen–Williams for frictional head loss in water pipes. Key elements of the technique are selecting the approximation domain and minimizing the relative error. A comparison for individual pipes over a range of diameter, roughness, and Reynolds number showed that the approximation provides ...

  • Preventing & Thawing Frozen Pipes

    A “how-to” guide on preventing and thawing frozen pipes. As temperatures drop below freezing around the country, it’s important to be informed of the cold weather’s effect on your water pipes. When temperatures are below freezing, pipes in unheated areas are subject to freezing causing messy, and often expensive issues. Just one burst pipe running at 4-8 ...

  • 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 ...

  • Measuring Pressure and Vacuum Correctly

    Pumps and systems are installed, started, operated, and many times, forgotten. When a problem arises, it’s recommended to install a discharge pressure gauge and suction vacuum gauge on the system. These gauges should be installed near the suction inlet and discharge outlet of the pump. These gauges are usually installed properly, recorded, and along with a pump speed measurement can be ...

  • Everything Depends on Pressure And Maintenance

    Energy and cost efficiency of biological treatment plants Every biologically working sewage plant needs a compressed air station for the oxygen supply of the aeration basin. This station only works at the highest possible energy efficiency level if excessive plant pressure through the subordinated system, excessive intake temperatures due to insufficient aeration and deaeration, and ...

  • In-pipe monitors turn dreams into reality

    In-pipe monitors turn dreams into reality The quality of tap water has improved enormously in recent decades, but for largely technological reasons, until recently, knowledge of water quality between the treatment works and the tap has been an almost impossible dream for water treatment and distribution network managers. In this article, Jo Cooper, Product Specialist at Intellitect Water, will ...

  • Optimal meter placement for pipe burst detection in water distribution systems

    Pipe bursts in water distribution systems (WDS) must be rapidly detected to minimize the loss of system functionality and recovery time. Pipe burst is the most common failure in WDS. It results in water loss out of the system, increased head losses, and low pressure at the customers' taps. Therefore, effective and efficient detection of pipe bursts can improve system resilience. To this end, ...
