  • Modeling for NAAQS Part 1: How to select the appropriate output for NO2

    The U.S. National Ambient Air Quality Standards (NAAQS) for 1-hour SO2, 1-hour NO2, and 24-hour PM2.5 use a very particular format. It is very important for all modelers (both within and outside of the U.S.) to understand how AERMOD handles this. In particular, U.S. users need to be familiar with the ...

  • Flood recovery project - Case Study

    Greener Waste Technology has been working with a utility company to combat the effects of flooding on a filter bed works. The works in question is low lying and next to a river which recently burst its embankment and flooded the filter beds entirely. The flood distributed large volumes of silt and mud onto the filters blocking the beds and starving the indigenous bacteria population of oxygen ...

  • Filter bed remediation - Case Study

    Biological filter beds usually consist of a mineral media over which effluent to be treated percolates. The media becomes host to a biomass which is grazed by a series of more complex organisms. If the growth of the biomass is greater than the rate at which the grazing occurs then the biomass film will accumulate in the bed. This will block the interstices of the media and restrict effluent ...

  • Modular Reed Bed - Case Study

    The modular reed bed is an award winning, innovative solution for small footprint tertiary treatment. This case study follows the implementation of this technology on a small and remote sewage works which was overloaded during high rainfall. This project saved 91% in costs for the effected utility (which had a budget of £300k for the project) and provided a reduced health and safety risk ...

  • Cost saving reed bed refurbishment innovation - Case Study

    Greener Waste Technology has designed a reed bed remediation programme that avoids the need to remove media or replace reeds. The process is a hybrid scheme incorporating the modular sludge settlement chambers utilised in the Modular Reed Bed system and the existing asset which is already in place. This type of remediation saves on project timescales and reduces risk as well as cost. The ...

  • Is a Horizontal Remediation Well System Right for My Project?

    So your remediation project is moving towards a choice of remedy, whether it involves Dual Phase Extraction, Total Phase Extraction, Biosparging, Soil Vapor Extraction (SVE), Air Sparge (AS), or Chemox Delivery, or any combination of the above. Now, the concept of horizontal remediation wells (HRW’s) for your site seems intriguing. So what do you need to consider before proposing a ...

  • In the depths of the oceans, human activities are beginning to take their toll

    Once seen as too remote to harm, the deep sea is facing new pressures from mining, pollution, overfishing and more. Imagine sinking into the deepest parts of the Central Pacific Ocean, somewhere between Mexico and Hawaii. Watch as the water turns from clear to blue to dark blue to black. And then continue on for another 15,000 feet (4,600 meters) to the seafloor — roughly the ...

  • Circular by design - Products in the circular economy

    This report explores the circular economy from a product perspective, applying a systemic approach and transition theory. Drivers of product design and usage are discussed in the context of emerging consumption trends and business models. For governance to be effective, it has to address the product life-cycle and the societal context determining it. Indicators and assessment tools are proposed ...

  • Blockchain Technology Can Boost Climate Action

    Experts meeting at the recent UN Climate Change Conference in Bonn in May have said that a new technology called “Blockchain” could play a major role in tackling climate change. A Blockchain is a distributed database that is continuously updated and verified by its users. Each added block of data is “chained” and becomes part of a growing list of records, under the ...

  • TurboScrubber® & TurboStripper® ‘TURBOCC’ Technology, for Flue Gas Cleaning & Carbon Capture System for Enhanced Plant Growth

  • Environmental Impact does NOT equal risk

    Auditing the new ISO 14001:2015:  Environment Impacts does not equal Risk In recent transition audits, there has been one common misconception that I have seen repeated, and that is that environmental impacts are risks.  This is not correct.  Environmental impacts do not equal risk. Let’s start ...

  • Enhanced Bio-Stimulation through Horizontal Wells

    Biosparging technology can be further enhanced when applied through Horizontal Remediation Wells. Since horizontal well systems typically have 4 to 10 times more screen footage in contact with the contaminated media than vertical systems, Horizontal Biosparge Wells can inject much greater volumes while maintaining the same low flow rates. This, in turn, leads to more rapid increases in dissolved ...
