Flue gas ducts: The system could be deployed in many industries as an effective gas treatment method, suggests Dr Suhan Kim. A green technology for eliminating odorous volatile organic compounds (VOCs) and their by-products has been developed by a group from the Korea Institute of Industrial Technology (KITECH). The research introduces a fuel-free technology for removing VOCs, thereby replacing incineration methods like thermal oxidizers and regenerative thermal oxidizers. This technology merges non-thermal plasma (NTP) with a wet scrubber (WS) system. Specifically, it employs atmospheric non ..read more

With advances in chip technology, odour sensors could become a commonplace feature of devices such as mobile phones. Seemingly significant strides with the miniaturisation and performance of olfactory sensors have been reported by researchers at the Hong Kong University of Science and Technology (HKUST), with an approach said to mimic human olfaction. Commentary from the group places such developments at the outset of a prospective revolution enabled by the digitization of odour. The digitization of visual information has been a transformative technology, an omnipresent feature of everyday lif ..read more

A mathematical model that maps the relationship between the molecular structure of odorous substances and how they are perceived is claimed to have an edge over human experts, when it comes to identifying smells correctly. A central undertaking of neuroscience is learning how our senses translate light into sight, sound into hearing, food into taste, and texture into touch. Smell is where these sensory relationships get more complex and perplexing. To address this question, a research team from the Monell Chemical Senses Centre and start-up firm Osmo – a spinout from machine learning work un ..read more

The system was used to sample air at around 30 and 65 feet in the air, and at three different times throughout the day. A “lab-on-a-drone” system has been used to monitor hydrogen sulphide gas from the air above a wastewater treatment plant in Brazil, in a project that has been written up in the American Chemical Society publication Analytical Chemistry. Hydrogen sulphide (H2S) – well known for its putrid, rotten-egg odour – is a problem pollutant associated with petroleum refineries and wastewater treatment plants. The gas is an irritant, and in high enough amounts, it can be toxic. Most met ..read more

Unit installed on a roof opposite the Green Star facility. A waste to energy (WtE) plant in northern Paris, known as the ‘L’étoile Verte’ or ‘Green Star’ waste recovery facility, which was originally built in an industrial area, is now surrounded by residential development. This has presented a number of challenges; not least of which is odour. The company ELLONA has therefore been contracted to establish a smart continuous odour and gas monitoring network, so that the sources of odour can be identified, and improvement measures can be underpinned by scientific data. “The ELLONA monitoring ne ..read more

A landfill site in Glasgow has been served with a civil penalty of £6,200 by SEPA for a breach of its environmental permit resulting in an offensive odour that affected local communities for eight days in June 2021 and 138 complaints. The Variable Monetary Penalty (VMP), the first in Scotland served by SEPA, was issued to Paterson’s of Greenoakhill Ltd due to offensive odour issues at the site between 8 and 15 June 2021. The company was also required to pay £1,156.35 of SEPA’s costs. Odour from the landfill site has had an impact on the local community for many years, says SEPA, which has us ..read more

Dustfighter All-In-One (AIO) Misting Cannons Said to be ideal for sites with limited water availability the new Dustfighter AIO from Envirogard comes top-mounted to its own IBC.  An integral pump delivers water from the 1000 litre tank to the ring nozzle and the fan sends out a plume of fine water mist to the air. Optionally Envirogard can equip the AIO with an automatic dosing unit to mix odour / dust suppressant concentrate to the water mist at point of use. The tank holds enough water for 2.5 to 3 hours operation – but simply connect a water supply and the AIO will automatically re-f ..read more

A study of two wastewater treatment plants in Cordoba, Spain evaluates the odorous impact of the technologies deployed in each. Aerating activated sludge: The process allows for the elimination of nitrogenous contaminating compounds from wastewater. The study appears to show that degrading wastewater pollution by means of mechanical aeration results in fewer odorous compounds than the use of intensive systems. A parallel study seemed to demonstrate that biofilters filled with pruning and sludge compost are efficient systems to minimize the odorous impact of sewage treatment plants. The odour ..read more
