Case study - Ice Blast technology for steam generator decontamination

Background At Point Lepreau NGS the Health Physics Department looked for alternative decontamination methods that could be applied to reduce the dose expenditure as a result of maintenance on the primary side of our steam generators. Due to the characteristics of the CANDU design (i.e., primary circuit being high purity D2O) introduction of foreign contaminants was also a concern. ...

Seawater desalination — a green technology?

The need for resource-saving, low-impact “green” desalination technologies is evident as the use of desalination accelerates in many parts of the world. The concept of “best available techniques” (BAT) aims at the identification of state of the art technologies, processes, or methods of operation which indicate the practical suitability for preventing or reducing pollution of the atmosphere, ...

Breakthrough in energy efficient desalination technology

Saltworks' proof-tested process employs an innovative thermo-ionic energy conversion system. The energy reduction is achieved by harnessing low temperature heat and atmospheric dryness to overcome the desalination energy barrier. The system works best in the dry regions that need water. Saltworks President Joshua Zoshi said, 'a desalination technology powered by atmospheric dryness is very much ...

Common Treatment Technologies for Nonhalogenated VOCs

Soil vapor extraction (SVE), thermal desorption, and incineration are the presumptive remedies for Superfund sites with nonhalogenated VOC-contaminated soil. Because a presumptive remedy is a technology that EPA believes, based upon its past experience, generally will be the most appropriate remedy for a specified type of site, the presumptive remedy approach will accelerate site-specific ...

The hidden risk of negative emissions technologies

Strategies for removing carbon from the atmosphere all have down sides. The biggest? Their ability to lull us into complacency. The best way to keep your floor dry is to avoid spilling a bucket of water onto the floor, rather than to deliberately tip the bucket and then develop technologies to dry the floor. The same is true of greenhouse gases: We need to prevent their ...

Sustainable wastewater separation treatment systems coupled with nutrient and water reducing greywater reuse technologies

Nationally and internationally, pressure is increasing to introduce nutrient reducing, water conserving and recycling measures for sustainable residential and small community water/wastewater systems. Reports of inadequate water quality and quantity are being reported daily. Over the past thirty years the federal government and State of Alaska have invested over 4 billion dollars installing piped ...

Dispersed Phase Inertisation (DPI): A New Technology for the Treatment of Landfill Leachate and Complex Water

Inertisation is thus far the only technology for the conversion of leachate and contaminated water into an inert product, thereby facilitating handling and disposal in MSW landfills. Introduction One of the most complex aspects of the global management of an MSW landfill or treatment plant is leachate. This liquid comes mainly from the degradation of organic matter, added to other ...

Using Venturi Scrubber Technology for Syngas Cleaning

As part of our nation's program to reduce dependence on fossil fuels, various gasification technologies are being applied. These processes take renewable organic material and, through the application of heat and pressure, convert the materials into syngas for further use. Arguably, in nearly all of these processes, the most critical design aspect is the reliable and efficient removal of ...

New monitoring technology helps reveal Arctic secrets

A group of Arctic researchers has employed the latest monitoring technology to investigate the effects of climate change, by measuring temperature and salinity in the water column beneath surface ice. The results of the investigation, which utilised YSI’s new 'Castaway-CTD', could cast new light on our understanding of the ways in which shifting ocean currents impact upon the climate in ...

Wet electrostatic precipitators: A preferred technology for emission control

The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...
