  • The reduction of water losses

    Leaks in water pipes and leaking valves in urban water distribution system and pipeline networks, mainly in developing and threshold countries, are the threshold countries, are the reason for water losses of up to 50% in relation to the water quantity being produced in the water ...

  • Water Loss UK 2012

    In May 2005 a seminar was held at the NEC in Birmingham to introduce the UK water industry to the work of the International Water Association (IWA) Water Loss Task Force. A similar event was held at the NEC Crowne Plaza Hotel in June 2009. Both events were well received and attracted over 100 delegates. Since then the WLTF has become a Specialist Group in IWA due to the importance ...

  • Determining Proper Cooling Tower Size

    To maximize water-based cooling tower benefits, the appropriate tower size must be selected, requiring the identification of several critical factors. Cooling towers are a relatively inexpensive and reliable way of expelling heat from a number of industrial processes, including nuclear & thermal power plants, petroleum refineries, petrochemical plants, food processing plants, as well as HVAC ...

  • Frostbite And Hypothermia Hazards

    Hypothermia and frostbite can be two of the serious consequences of working outdoors in winter weather. Hypothermia is a dangerous lowering of the body’s temperature by exposure to cold or wet conditions. Actually, the air temperature doesn’t have to be particularly low to cause hypothermia – just getting wet and chilled can do the same thing. Hypothermia can be fatal. ...

  • ´More Stations. More Data. Better Forecasts.´ – the NYS Mesonet

    “More Stations. More Data. Better Forecasts.” – that’s the slogan of New York State Mesonet. The weather observation network consists of a total of 125 weather stations all over the state of New York and Lufft was selected as one of the vendors to support them in capturing the data. All 125 of the weathers stations have the standard instrumentation suite. Of those 125, 17 ...

  • Capturing biogas energy to increase your business profits while safeguarding the environment

    Methane is a biogas produced from swine or cow manure, as well as food processing and meat packing waste. Methane is a natural gas, that when left uncollected, contributes to the harmful greenhouse gases in the earth’s atmosphere. When biogas is captured under a cover and becomes concentrated, it creates a corrosive and toxic byproduct called hydrogen sulfide. The gas generates a rotten egg ...

  • Insertable Valve Network Provides OngoingSolution to Water Loss

    Orange Cove, CA - As the only city in Fresno County that is completely dependent on surface water, the City of Orange Cove had 40% unaccounted for water loss when Bill Little, former City Manager returned to Orange Cove to address the community’s growing water problems... “Our goal is to reduce unaccounted for water loss in Orange Cove down to 3% - 5%,” explained Little. “In a city with an old ...

  • Water Loss management will be critical to climate change adaptation

    Water loss management is one of the most important issues facing water suppliers around the world. The Sustainable Development Goals have made poverty alleviation and access to safe drinking water a political priority. Targets on providing safe drinking water as a basic human right aim to ensure everyone can access a safe water supply. Unfortunately, the reality is that many of the most ...

  • Strategic Planning for Water Loss Reduction with Imprecise Data

    Water utilities particularly in the developing countries continue to operate with considerable inefficiencies in terms of water and revenue losses. With increasing water demand and scarcity, utilities require effective strategies for optimum use of available water resources. Often the information needed for strategic planning is inadequate and decisions have to be made on the basis of limited and ...

  • Bayesian modelling for water loss management decisions

    Bayesian networks and their associated methods are especially suited for capturing and dealing with uncertainty. They can be successfully applied both in engineering sciences and in reliability analyses of water distribution systems. In this paper we propose an interactive Bayesian network and a decision-theoretic system which intend to monitor water loss, predict likely outcome and select ...

  • Raw material cycle: from chip to briquette to product - Case Study

    Thanks to their briquetting system from RUF Frischhut can redeploy production scrap and melt it again Ludwig Frischhut GmbH and Co. KG have closed the circle on their raw material cycle by utilising a briquetting press from RUF: cast chips produced during the machining of parts for water supply and sewage disposal are pressed to solid briquettes and then melted in the in-house foundry and ...

  • Wasting energy through steam loss

    The European Union Directive on the Energy Performance of Buildings, which relates to all member nations of the European Union, are obliged to set limits on greenhouse gas emissions, particularly from buildings. Typically steam is used for a wide range of applications within larger establishments including, humidification, hot water, space heating and air heating.  Primary energy losses in ...

  • Application of MUSLE for the prediction of phosphorus losses

    Soil erosion in forestlands affects not only land productivity but also the water body down stream. The Universal Soil Loss Equation (USLE) has been applied broadly for the prediction of soil loss from upland fields. However, there are few reports concerning the prediction of nutrient (P) losses based on the USLE and its versions. The present study was conducted to evaluate the applicability of ...

  • Automated determination and evaluation of water losses in water distribution systems

    Using conventional methods and tools for determining detailed zonal water balances and performance indicators involves considerable efforts in manual data collection and processing. Hence, water balances mostly are determined for a whole network only. Unmetered components are often neglected or based on rough estimates. This article presents an approach to the automated determination of zonal ...

  • Tackling water losses through improved domestic water bills

    The domestic water bills that municipalities send out to consumers on a monthly basis are a key interface between local government and citizens. Being a legal instrument, as well as a communication medium, the consumers' level of understanding of their water bills and the confidence in the information provided is therefore indicative of their effectiveness. A lack of understanding of bills ...

  • Reduction in water losses in water distribution systems using pressure reduction valves

    Water loss is a phenomenon frequently observed within water distribution systems (WDSs), that is considerably worsened by an excessive pressure throughout the network. As an alternative option to pipe replacement, the use of pumps working as turbines, throttle control valves (TCVs), or pressure reduction valves (PRVs) can be used to reduce leakage. For a preassigned number of these devices, ...

  • 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 ...
