  • Water Treatment Plant: Benefits of Underwater Cameras

    Before fresh water can be made safe for human consumption it must go through a treatment process eliminating bacteria and any other elements deemed unsafe to drink. How does such a process occur and why is it relevant to us? We’ve written about the use of Deep Trekker remotely operated vehicles and pipe crawler systems in storm water systems, sanitation pipes, and water storage basins. A ...

  • PULSE makes explosive readings

    About Kockums AB The Danes haven’t always been on the best of terms with their neighbours in Sweden! The late1600s were troubled times in the Baltic. Having conquered the provinces of Skåne, Blekinge and Halland from Denmark, the then Swedish King Karl XI realised that he needed a naval base in the south of Sweden to defend these new acquisitions. Therefore, Karlskrona was ...

  • Environmental impacts of ocean-energy systems: a life-cycle assessment

    Ocean-energy technologies — which harvest renewable energy from the sea — will have a significant role to play in a future low-carbon society. A recent life-cycle analysis of different ocean-energy devices has found that life-cycle environmental impacts are caused mainly by the materials used in the mooring, foundations and structures. Improving the efficiency and lifespan of the ...

  • Orange county goes green

    As individuals, many Orange County residents help fulfill the mandate to be environmentally conscious by recycling plastic bottles and aluminum cans, employing strategies to reduce domestic water consumption and making personal transportation more fuel-efficient.

  • How to Repair Pipes Quickly with Minimal Service Disruption

    If this has not yet happened to you, it will. The time is 5:30 a.m. and your guests are just beginning to wake when you get an emergency call informing you that a pipe has sprung a leak. What are your options? Will you shut down the water for a few hours, leaving your guests without water to brush their teeth, take their showers, or flush the commodes while you cut out and replace the bad ...

  • ELECTRONIC WATER TREATMENT REDUCES FOULING AND CORROSION IN PIPELINES

    Increasing pressure loss in the pipeline is often caused by scale corrosion or product fouling of the internal surfaces. This condition slows transmission and distribution capacity, and can require more than just routine maintenance if it remains unaddressed. Interior corrosion, fouling and leakage in pipeline systems will adversely impact bottom-line operations. ...

  • Asia Analysis: Battling climate impacts in low-lying Maldives

    Going carbon neutral and protecting marine environment are key to fighting climate change in the tiny island nation, says Nalaka Gunawardene. ‘Raise your voice, not the sea level’ is the theme for this year’s World Environment Day, which falls on 5 June. The theme resonates with the United Nations designating 2014 as the International Year of Small Island Developing ...

  • Electronic water treatment reduces fouling in heat exchangers

    The deposition of material on heat transfer surfaces is called fouling which significantly impacts on the thermal and mechanical performance of heat exchangers. Fouling increases the overall thermal resistance and lowers the overall heat transfer coefficient of heat exchangers as well as impeding fluid flow, accelerating corrosion and increasing pressure drop across the heat ...

  • Joint action on climate change: Facts and figures

    Ilan Kelman examines the history, overlaps and conflicts between climate change, development and disasters. By the end of 2015, three global policy processes will have set the stage for how the world responds to major challenges facing humanity in the years to come. A voluntary agreement to tackle disasters was reached in ...
