  • Sustainable odour control in urban environments

    Abstract With an ever increasing focus on sustainability, the municipal recycling sector is increasingly locating recycling facilities in urban environments to be closer to their waste sources. The odour control industry needs to respond in providing ever more efficient odour extraction technologies to minimise any odour nuisance to their residential community neighbours. ...

  • High efficiency odour control for wastewater treatment

    Since the banning of sewage sludge disposal at sea in 1998 secondary treatment of sludge is now a vital part of waste water treatment. Initially many water companies opted for incineration, but over the last 10 years other options have been adopted such as producing stabilised sludge and pelletised dried sludge for use as fertiliser for agriculture. Currently over 62% of sludge is used in ...

  • Odour Nuisance - Where We Are and Where to Next?

    Prior to 1990 there were very few examples of effective odour control schemes at sewage treatment works. Sources were often not properly identified, much less quantified and budgets did not allow the introduction of properly engineered solutions. Since then, in response to a seemingly endless increase in pressure from public, considerable progress has been made tackling the problem. First ...

  • Electronic nose sniffs out odour pollution

    The science of smell is set to enhance air quality in the UK, thanks to the development of a pioneering ‘electronic nose’ for industrial odour monitoring.   Available in the UK for the first time, the technology can be used to help improve the control of odours associated with industries such as waste storage and recovery, sewage treatment, composting, chemicals and food ...

  • High Rate Biological Odour Control Demonstration for Biosolids Exhausts

    Abstract Biorem has successfully demonstrated its high rate odour control system for biosolids exhausts at Ashbridges Bay sewage treatment plant in Toronto, Ontario. The demonstration used XLD™, a biofiltration media engineered specifically for biosolids odours. The system has achieved 95% odour removal in less than 20-s Empty Bed Residence Time (EBRT) despite high concentration of ...

  • Sewage of Tripoli: a review of the current situation and of the future planning

    Tripoli represents a major urban area in Lebanon with about 350,000 people in the city, which may swell by additional 100,000 when the city surrounding population is counted. It used to be a dominant agricultural region, but the last three decades witnessed a rapid development of urban construction. The goal of this paper was to present the current situation regarding the sewage disposal, ...

  • Purification of domestic sewage by water-hyacinth (Eichhornia crassipes)

    Sewage management is posing serious techno-economic problems in cities, particularly in developing countries. A new technology, sewage purification by water-hyacinth (Eichhornia crassipes), is a possible solution. This paper studied the suitability and effectiveness of water-hyacinth in treating domestic sewage. A 28-day experiment was performed under a controlled environment of a screen-house ...

  • Co-composting of sewage sludge and municipal solid waste

    Israel production of sewage sludge and MSW grows each year due to the increasing number of modern Wastewater plants that are using activated sludge process and the increasing population. Non-stabilized Sewage sludge is an environmental nuisance due to high level of pathogens, offensive odours, insect attraction and potential water sources pollution. The Haifa region itself, where the study took ...

  • The use of sewage sludge compost for improving reedbeds performance

    In a wastewater of medium strength, about 75 % of the suspended solids and 40 % of the filterable solids are organic in nature. The parameter used for measuring the strength and the quantity of the organic substances in the wastewater is the Chemical Oxygen Demand (COD) (Aggelakis and Tchobanoglous, 1995; Tchobanoglous and Burton, 1991). Degradable organic matter in wastewater, whether soluble or ...

  • Solar drying of sewage sludge - An old method with modern technology using Wendewolf®

    Any Sewage Water Work throughout the world will produce sludge, a form of biomass growing in the basins. This biomass has to be evacuated and is, generally speaking difficult to handle! When liquid it has a dry matter of 3 to 4 %, or only 30 to 40 kg per ton of sludge, when mechanically dehydrated to 20 - 25 % most of it is still water, as an average  750 to 800 kg per ton of filter cake. ...
