  • Alternative water supply and treatment solutions in Durban (SA)

    As a result of persistent drought conditions in South Africa a customer (an international consumer goods producer with a production facility in Durban) experiences the pressure of limited availability of water. The ever dropping dam levels currently result in higher risk for intermittent water supply resulting in unplanned and forced production stops in case no water is available. Aquest Colsen ...

  • European water policies and human health — Combining reported environmental information

    Society depends on the satisfactory and sustainable management of water. Historically, the primary purpose of water treatment was to protect human health, through reducing disease being transmitted through water. Subsequent measures to address environmental concerns have broadened our expectations of what water and waste water treatment should deliver. This report considers three pieces of EU ...

  • Porirua New Zealand – WaStop® DN225 - Case Study

    Porirua City located 20 km north of Wellington has over 70 storm water outlets into the harbour. A number of these outlets are very flat on their approach to the harbour which generally means they are severely influenced by high tides. The problem with these outlets is that if a rain fall event coincides with a high tide, the ability of the storm water network to discharge is severely restricted. ...

  • 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 ...

  • Reaching economic leakage level through pressure management

    High non-revenue water (NRW) values as a percentage of system input volume form a serious problem that many water utilities worldwide have to confront nowadays. There are ways to mitigate the effect by adopting strategies with short- and long-term results. Water pressure management (PM) is one of the most efficient and effective NRW reduction strategies. To calculate pressure management of ...

  • Water Level Measurements-Part 1

    Confused about which instrumentation to use in your water level monitoring system? In-Situ offers two categories of pressure sensors for water level measurements: absolute or non-vented sensors, and gauged or vented sensors. They look the same and both measure pressure and water level, but they have drastically different applications, outputs and accuracy. The absolute (or non-vented) water level ...

  • Intermittent operation of low pressure UF membranes for sewage reuse at household level

    A household-scale wastewater treatment system was operated with domestic sewage. The system could recover gardening/irrigation water from raw sewage or secondary effluent by low pressure ultrafiltration (UF). The UF membranes (surface area = 3.5 m2, pore size = 0.04 μm) were operated at constant transmembrane pressure (0.13 bar). The proposed technology was examined for ...

  • European waters - assessment of status and pressures

    EEA 2012 'State of Europe's water' assessments 2012 is the European year of water in which the European Commission published its 'Blueprint to safeguard Europe's waters' (referred to hereafter as the Blueprint) comprising reviews of the Water Framework Directive (WFD) (2000/60/EC), water scarcity and drought and adaptation to climate change policies. To accompany and inform the blueprint, ...

  • Determination of diurnal water level fluctuations in headwaters

    The aim of this paper is to study diurnal fluctuations of the water level in streams draining headwaters and to identify the controlling factors. The fieldwork was carried out in the Gryżynka River catchment, western Poland. The water levels of three streams draining into the headwaters via a group of springs were monitored in the years 2011–2014. Changes in the water pressure and water ...

  • The joint effect of water price changes and pressure management, at the economic annual real losses level, on the system input volume of a water distribution system

    This study attempts to examine the factors affecting the residential water demand level in the city of Kozani in Greece. Based on an 8-year (2005–12) detailed sample of residential water demand panel data, the values of the water price (WP) elasticity of residential demand are identified, and the influence of socio-economic and demographic factors and climate conditions on water-use levels and ...

  • Water Pressure Measurement with Time Domain Reflectometry Cables

    Attributes of the remote measurement of piezometric water pressure and water level with time domain reflectometry (TDR) techniques are investigated. The evaluation includes a two-wire system for unusually small riser tubes as well as parallel wire and air-filled or hollow coaxial cable for typical installations. Comparison of TDR cable and commercial pressure transducer technology shows coaxial ...

  • Knowing All About Hot Water Pressure Washers

    Two types of hot water pressure washer machines are currently available: ordinary hot water machines and tri-mode machines. Before going into details of these machines, it would be worthwhile to have a look into some of their basic aspects. Basic Features A hot water pressure washer can provide an output temperature of up to 210°F. For this, these machines should contain ...

  • A Comparison between Steam and Hot Water Pressure Washers

    Steam pressure washer machines are a gradual extension of hot water pressure washers. The main difference lies in the output temperature. While steam pressure cleaners provide an output of 330 degrees Fahrenheit, hot water machines offer an output pressure of 210 degrees Fahrenheit only. The other important specifications, such as output pressure and technologies present, do not change much ...

  • A new method estimates TEG purity versus reconcentrator temperature at different levels of pressure in gas dehydration systems

    There are several processes and principles for obtaining high triethylene glycol (TEG) purity in gas dehydration process. All methods are based on the principle of reducing the effective partial pressure of water in the vapour space of the glycol reboiler, and hence obtaining a higher glycol concentration at the same temperature. One of the most common methods for enhancement of the glycol ...

  • 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 ...

  • Evaluating changes in water institutions: methodological issues at the micro and meso levels

    ABSTRACT Institutions (formal rules) governing water allocation and use are often critical to a nation's development and prosperity. It is often necessary to change water institutions as economic, physical and political circumstance change.
