  • Water Risks on the Rise for Three Global Energy Production Hot Spots

    Energy runs on water. In fact, among industries, the global energy sector is the world’s largest water user. Almost all forms of energy production and power generation depend upon water for their operations. This tension causes stress in both the energy and water worlds. Three-quarters of energy respondents to a ...

  • Energy and exergy analysis of Hybrid Ground-Coupled Heat Pumps with hot water supply

    The energy and exergy efficiencies of a Hybrid Ground-Coupled Heat Pump (HGCHP) system with Domestic Hot Water (DHW) supply are analysed based on experimental study. Comparisons between the HGCHP and conventional DHW systems, i.e., Air Source Heat Pump (ASHP), Electric Heater (ElcH) and Gas-Fired Boiler (GasB), are made with respect to the energy and exergy efficiencies. The results show that the ...

  • Chemical disinfection of Legionella in hot water systems biofilm: a pilot-scale 1 study

    Legionella bacteria encounter optimum growing conditions in hot water systems and cooling towers. A pilot-scale 1 unit was built in order to study the biofilm disinfection. It consisted of two identical loops, one used as a control and the other as a ‘Test Loop’. A combination of a bio-detergent and a biocide (hydrogen peroxide + peracetic acid) was applied in the Test Loop three times under the ...

  • Water, water everywhere: But is there enough to drink?

    Original story at MIT News At MIT, experts address the challenges of supplying clean, safe water to a growing world population. The challenge of supplying clean, safe drinking water to an expanding world population comes down to money, MIT economist Franklin Fisher ...

  • The Effectiveness of Combined heat and Power Solar Water Heating Systems

    Abstract: Solar water heating in residential and commercial buildings is often provided by integrating a large number of domestic thermosyphon solar water heaters. The economic effectiveness of solar Domestic hot water heating systems depends mainly on its types and configurations. Thereupon in this paper, simulation models have been presented for the modeling of thermal and electrical ...


  • Water: the natural choice - safe, natural water delivers better comfort, lower cost

    Using water to heat or cool your building is the safest alternative, as hydronic systems can be installed and serviced by any licensed professional contractor. Because other refrigerants are toxic, they must be installed by specially trained technicians. You'll see those same technicians on expensive service calls installing factory replacement parts because components are not interchangeable ...

    Better Planet was selected to design, supply, install and commission two brine to water heat pumps with a combined thermal output of 70 kW for this castle in Oxfordshire replacing oil heating. In preparation of the project, Better Planet carried out a room by room heat loss calculation allowing us to advice the client on required upgrades of radiators in ...


  • When going green saves money, water, the soil, and plant life

    In the current economy, finding solutions to cut water consumption while reducing the expense of fertilizer has caught the interest of the agricultural industry, lawn care professionals, homeowners and gardeners across the country. Even though the rising cost of water garners little attention in the news, water prices have doubled and tripled in many parts of the nation. In the end, that steady ...


  • Water vapour permeation measurement for PV Solar Cell packaging

    With fears of carbon dioxide causing global warming and diminishing supplies of fossil fuels, a looming energy crisis is affecting all countries.  As a consequence, a great deal of world-wide effort is going into the development of alternative energy technologies.  At present, wind, hydro and geothermal are becoming well established with more niche roles for tidal and solar. The latter ...

  • Recovery of Precious Metal Catalysts - A New Process Using Supercritical Water Oxidation

    Up to now, the recovery of precious metals used as catalysts in chemical processes has involved the use of incineration. Now, however, a British-Swedish joint venture has developed a process which uses supercritical water oxidation instead, which provides many economic and environmental advantages. Precious metals are used extensively in catalysts in a wide range of industrial chemical processes. ...

  • Bacteria-free water - without the use of toxic chemicals - Case Study

    Aarhus University Hospital fought against Legionella bacteria – and won Legionella bacteria thrives in all hot-water supplies and Aarhus University Hospital, Risskov felt the problem firsthand. With the ECA generator from Danish Clean Water A/S they managed to significantly reduce the bacteria and thereby minimizing risks concerning Legionella. Virtually all hospitals, ...

  • Transfer of phthalates from c-polyvinyl chloride and cross-linked polyethylene pipe (PEX-b) into drinking water

    Several different materials have been used for production of domestic water pipes throughout history. In recent years, the use of cross-linked polyethylene (PEX) pipe has increased dramatically, yet the potential for leaching of phthalates, which are endocrine disrupting compounds associated with adverse reproductive effects in humans, has not been examined. In this study, the potential of ...
