  • Water Reuse Terminology

    All water on Earth is used and reused, over and over, in an elegant water cycle. Water reuse occurs in various ways on a daily basis. It happens when a community’s treated wastewater is discharged into rivers or other water bodies. If you live in a community downstream of another, chances are you are reusing water from an upstream town. Scientifically proven advances in water technology ...

  • Tackling waste in the sands of the Sahara

    When gas was discovered in the mid Sahara areas of North Africa in the 1990s Andy Ive was asked by BP to help set up the water and waste infrastructure for what amounted to four small towns 600 km into the desert. No local infrastructure at all existed for the waste and water to be produced by 2-3000 workers. IVE overcame sandstorms, extreme heat, poisonous snakes and patented a novel solution to ...

  • 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. ...

  • Anaerobic digestion in the United Kingdom

    Anaerobic digestion (AD) has been used to treat sewage sludge by the United Kingdom’s (UK) water industry for over 100 years. More recent years have seen a revolution as AD has swiftly expanded into agricultural feedstocks and food waste. Data from the Waste Resource and Action Programme (WRAP) shows that in the past year alone, there has been a 46 percent growth in the size of the sector. ...

  • How new technologies are shrinking wastewater’s hefty carbon footprint

    Wastewater treatment plants are energy hogs. A 2013 study by the Electric Power Research Institute and Water Research Foundation reported that they consumed about 30 billion kilowatt-hours of electricity per year, or about 0.8 percent of the total electricity used in the United States. Wastewater treatment’s high energy footprint is ironic because the organic matter in wastewater contains ...

  • Cities are finally treating water as a resource, not a nuisance

    From Houston to Melbourne, the surprising ways urban areas are dealing with water woes Memorial Day barbecues and parades were thwarted this year in Houston when a massive storm dumped more than 10 inches of rain in two days, creating a Waterworld of flooded freeways, cars, houses and businesses, leaving several people dead and hundreds in need of rescue. ...

  • Home, Sweet Wastewater Building

    How can a wastewater treatment plant embedded into a neighborhood not use much landmass and be environmentally friendly and user-friendly all at the same time? One system aims to do all of the above. Why should a wastewater treatment plant always have to look like, well, a wastewater treatment plant?  A visual trip through project files of Aqueonics Inc., based in Greenville, SC, reveals photos ...

  • The Potential of Solar-Powered Water Circulators to Help Solve Serious Water and Energy Problems in the U.S.

    With increasing human populations comes the corresponding increased need for improving water quality in lakes, wastewater ponds, potable water reservoirs, and other water storage facilities. Providing circulation within water reservoirs of all types has long been known to provide meaningful benefits, but the costs to achieve sufficient circulation through diffused aeration or mechanical mixers ...

  • The search for sustainable plastics

    As petroleum-based polymers foul our oceans and litter our lives, researchers seek more environmentally friendly ways to meet demand for durable, versatile materials. The fate of the world’s oceans may rest inside a stainless steel tank not quite the size of a small beer keg. Inside, genetically modified bacteria turn corn syrup into a churning mass of polymers that can be ...

  • Environmental Situation in Africa

    Abstract Africa The economic and social needs of Africa depends more on its environmental resources but these natural resources are seriously declining and that is really effecting the entire region. Sustainable development in this rapidly changing region has become an imperative, and must take place in the complex context of a diverse and changing ecosystem, political transition and evolution ...

  • Mixed MSW composting in transition

    WITHOUT a doubt, composting the mixed municipal solid waste stream is a “niche” business. It is an MSW management option that seems to be viable in very specific situations. In some instances, these plants were built to service tourist destinations, often in somewhat rural areas where recycling is difficult and landfills are distant. In several other cases, public agencies built plants to extend ...
