Environmentally friendly - Tank in a box

by Superior Tank Co., Inc.  (Mar. 10, 2015)

Bolted steel water storage tanks have been used for many years with great success and low levels of environmental impact.  Individual steel panels are precision crafted in dedicated factories, then assembled on the job site. As only a small amount of work is required in the field, local impact is very minimal.  Bolted steel storage tanks ...

Future-oriented further developments: wastewater heat utilization plants with a return on investment (ROI) of 2 - 6 years

by RABTHERM AG  (Mar. 9, 2015)

Sewage is dirty and stinks. Out of sniffing distance – out of mind. Up until the 1980s sewage was taboo and not given the attention it deserves. One cold winter morning in 1988, 23 years ago, Urs Studer stopped beside a steaming manhole cover and wondered how such a source of heat could go untapped. Ever since he has been dedicating himself ...

The European environment — state and outlook 2015 — synthesis report

by European Environment Agency (EEA)  (Mar. 2, 2015)

In 2015, Europe stands roughly halfway between the initiation of EU environmental policy in the early 1970s and the EU's 2050 vision of 'living well within the limits of the planet' (1). Underlying this vision is a recognition that Europe's economic prosperity and well-being is intrinsically linked to its natural environment — from fertile ...

Recycling Using Antifreeze with Electrodionization

by Ultra Pure EDI Components  (Mar. 13, 2015)

Recycling used antifreeze makes sense for two reasons: 1) It is cost-effective, and 2) It saves resources. Ethylene glycol, the primary active ingredient in antifreeze, is produced from natural gas, which is a finite, non-renewable resource. For businesses that use a lot of antifreeze, like automobile repair shops, setting up an antifreeze ...

Validation of the Goreangab Reclamation Plant in Windhoek, Namibia against the 2008 Australian Guidelines for Water Recycling

by IWA Publishing  (Mar. 13, 2015)

Australia has had Guidelines in place for water recycling (for all uses other than the augmentation of drinking water supplies) since 2006. These Guidelines were extended to cover potable reuse in May 2008 and have been applied to two potable reuse projects in Australia – one a trial plant in Perth, Western Australia and the second for a ...

Cost comparison of seawater for toilet flushing and wastewater recycling

by IWA Publishing  (Feb. 6, 2015)

As freshwater resources are becoming increasingly scarce, unconventional sources of water should be given new consideration. In coastal cities, seawater, with minimal treatment, can be used for toilet flushing, reducing the demand for freshwater. Currently, it is practised on a large scale only in Hong Kong. This study estimates the cost of ...

Oil refinery experience with the assessment of refinery effluents and receiving waters using biologically‐based methods

by John Wiley & Sons, Ltd.  (Mar. 24, 2015)

The trend in discharges of petroleum‐related substances from refineries in Europe shows a consistent picture of declining emissions, since first measured in 1969. This decline coincides with enhanced internal capture or recycling procedures and increasing use of physical and biological treatments. At the same time, and partly in response to ...

Risk-based planning for water recycling in an Australian context

by IWA Publishing  (Dec. 15, 2014)

Australia has seen an unprecedented proliferation in large scale water recycling schemes since the late 1990s. This has been driven by a recent decade of drought, policies to encourage water efficiency in new homes and buildings in urban areas, and to reduce pressure on rain-fed water supplies by replacement with alternate water sources in rural ...

Technology Convergence Based on Recycle and Recovery Crucial to Address Water-Energy Challenges

by Frost & Sullivan  (Dec. 31, 2014)

Energy and water are interdependent and require each other to be available for human consumption. The importance of water and energy interdependence has started gaining recognition across the globe and also resulted in increased interest in further understanding of the concept. The wide-ranging implications of the water-energy nexus necessitate ...
