  • Importance of Inspecting Reservoirs

    Inspecting Reservoirs – what is the importance of them, why they are inspected, and how ROVs help pave the way for low-cost, regular maintenance. What is a Reservoir? Deriving from the French word réservoir meaning “storehouse,” a reservoir is exactly that – a storage place for water. More often than not, these bodies of water are ...

  • Oil Sampling Best Practices

    Obtaining a representative oil sample from a closed loop lubrication system is essential to any good oil analysis program. As oil analysis programs become more standardized for routine monitoring, especially within equipment warranty support programs, equipment makers provide more sampling points on new equipment. These ...

  • The Water Conditions in Ethiopia, Part Two

    While in Ethiopia in August to learn more about what they do about drinking water, I visited the Debre Damo Monastery. About 1,600 years old, it is situated on a flat-topped outcropping of solid rock. The only way in or out is by climbing a sheer cliff using a 15 meter rope made from woven rawhide. The top supports a community of about 150 monks. Certainly the most extreme location I found people ...


  • The Water Conditions in Ethiopia, Part One

    In August, I was able to visit northern Ethiopia to look at some of the drinking water issues. As you might guess, there are many, ranging from polluted water to almost no water at all. That made it interesting to discover the inhabitants of Adwa and Aksum rely on a reservoir. The reservoir water is treated first by aeration to oxidize iron, then with a flocculant which attracts dirt like a ...


  • Structural conditions in German water supply

    Against the background of price controls for drinking water supply utilities in Germany, the comparability of utilities with regard to their specific structural conditions comes into focus. Relevant structural conditions were identified for the two main technical processes, namely water production (WP) and treatment, storage and distribution (TSD). A defined clustering process for comparable ...

  • Total Dynamics of Quartz–Water System at Ambient Conditions

    New data on the dissolution and growth of quartz in acid, nearly neutral and slightly alkaline solutions at ambient conditions are presented. During batch dissolutions, aqueous Si-concentrations increased nonlinearly towards limit values. During parallel growth experiments, however, the high Si-concentrations corresponding to 13-fold supersaturation with respect to quartz did not decreased. To ...

  • What is the Impact of Seabed Conditions?

    Eirik Byklum, Statoil, has commented that: “developers have learnt the hard way that poor conditions on the sea bed can have a very negative impact – they are much more aware of this and its cost implications” How important are seabed conditions for your offshore wind business? Alongside distance to shore, water depth, and wind conditions, seabed consistency has a major ...

  • The Benefits of Biogas Conditioning

    Abstract Anaerobic digestion is quickly becoming the choice technology for sewage sludge treatment at wastewater treatment plants, as the methane rich biogas produced is a valuable resource which can be used to generate electricity. In the oxygen restricted environment, a natural by-product of the anaerobic process is hydrogen sulfide, a harmful contaminant. Also present in the biogas are ...

  • Improved oxygen conditions in the Baltic deep water

    Oxygen conditions in the south eastern Baltic have improved thanks to an inflow of oxygen-rich water from the North Sea during November/December 2011. This inflow has also caused the concentrations of phosphate and silicate to increase in the surface waters, which could cause excessive algal blooms this summer. As a result of the relatively large inflow from the Kattegat to the Baltic ...

  • Water supply in Jordan under drought conditions

    This paper discusses the Mujib Dam reservoir's storage during the drought years of 2007–2009. It has been concluded that the policy of unplanned water release during the dry year 2007, when little attention was paid to the possibility of a continuation of the drought, contributed to the remarkable lack of surface water storage during 2008, another dry year. For better management and planning, ...

  • Effect of different water conditions on dissolution of nanosilver

    This study evaluates the time-dependent dissolution of nanosilver (nAg) in common electrolytes and natural waters. nAg was synthesized via Tollens’ method using sodium citrate as stabilizer; its morphology, UV–Vis spectrum, and particle size were characterized. The dissolved silver was monitored over time using filtration, centrifugation, and inductively coupled plasma atomic ...

  • Developing Reference Conditions For Phytoplankton in The Baltic Coastal Waters

    For the implementation of the Water Framework Directive reference conditions have to be established for the various quality element. In this report we outline a number of approaches that can be pursued for establishing reference conditions for phytoplankton at a regional level and discuss the problems associated with their application. This report does not exhaust the topic of establishing ...


  • Air Conditioning That`s Out of This World

    New materials enhance the cooling effects from outer space to reduce energy use in small- to medium-sized buildings Reducing air conditioning energy use by using new materials to enhance the cooling effects from outer space may not be such a far-out idea. In a simulation study using DOE's Energy Plus software and ...

  • Fires at Composting Facilities: Causes and Conditions

    The subject of fires at composting facilities is a bad news/good news situation. The bad news is that fires are more common than we realize. Ask a group of facility operators if they have had to deal with a fire, and the majority will quietly admit they have. The good news is that we don’t realize that fires are fairly common at composting facilities. Most are neither frequent nor destructive ...

  • Managing Great Lakes Water Levels Adaptively in Response to Changing Climate Conditions

    The Laurentian Great Lakes contain an abundance of fresh water, collectively representing approximately 20% of the fresh surface water available globally. Despite the enormity of this resource, water levels and flows in the Great Lakes are subject to fluctuations caused by changing climate conditions that have cascading impacts on the coastal ecosystem and the regional economy. Proactive ...
