  • MSW Management: Safely Countering the Rise of Landfill Odors

    One of the core challenges of landfill and compost site management is fighting the rise of foul odors. In addition, as communities expand further out from previous areas, they eventually become neighbors to landfills – calling for a comprehensive odor-control approach to countering odor complaints. In fact, compared to other industrial applications such as wastewater treatment and asphalt ...

  • The smell of success. Odour management in sludge treatment

    Production of municipal solid waste (MSW) is increasing worldwide, although many – primarily industrialized - countries are making major efforts to cap that growth. In France, for example, MSW production has tripled over the past 25 years. In 2006, the country produced 30 million metric tonnes of municipal solid waste, with a substantial portion of this waste ending up in landfills. In keeping ...

  • A review on sludge dewatering indices

    Dewatering of sludge from sewage treatment plants is proving to be a significant challenge due to the large amounts of residual sludges generated annually. In recent years, research and development have focused on improving the dewatering process in order to reduce subsequent costs of sludge management and transport. To achieve this goal, it is necessary to establish reliable indices that ...

  • The increasing importance of assessing toxicity in determining sludge health and management policy

    The harm caused by toxic industrial effluents to sewage treatment works, has been recognised for many years. These can cause reduction in biodegradable efficiency, with an associated requirement for longer treatment time, and in extreme cases, toxic shock can kill off the secondary tanks. Currently, the presence of harmful industrial effluents is made evident by their effects ...
