  • Incineration Industry: Scrubber on Sludge Incinerator Reduces Atmospheric Emissions Case Study

    Aberdeen Sewage Treatment Plant in Aberdeen, Washington started up their new Electric Infrared Incinerator in May, 1981. The sewage sludge incinerator, product of Shirco, Inc., needed a pollution control device in order to meet state, local and federal requirements for atmospheric emissions, according to the emissions test on the unit performed January, 1982. Chosen was a Model 24×24- ...

  • The impact of advanced digestion on incineration of sewage sludge

    Abstract Traditionally, when incineratin sewage sludge, it was preferable to burn raw undlgested sludge, as digestion - by extracting some of the energy from sludge- subsequently reduce its calorific value. However, when considering incineration as part of a wider strategy, the desicion whether or not to include digestion becomes less clear. Since, virtually all of the requirements of ...

  • From raw incineration to advanced digestion – influence of sustainability on meeting a sludge strategy

    Abstract A proposed solution of a raw sludge incineration plant had been identified to meet the changing sludgestrategy requirements of United Utilities (a major UK water company) from 2005 – 2010. This solution wasendorsed by a UK water Regulator as part of their 5 yearly investment program. However, due to a changingenvironment, and work completed by the project and strategy team ...

  • Minimization of Major Air Pollutants from Sewage Sludge Fluid Bed Incinerators

    ABSTRACT Emissions of major air pollutants including carbon monoxide (CO), nitrogen oxides (NOx) and mercury (Hg) were studied at two sewage sludge fluidized bed combustion (FBC) plants. Both the North West Bergen (NWB) County Utility Authority and the Little Miami (LM) plants have air pollution control systems (APCS) that are of the wet type. Various operating conditions such as temperature, ...

  • Separation of metals and phosphorus from incinerated sewage sludge ash

    Microbial acidification of incinerated sewage sludge ash and dissolution of metals from the acidified ash were investigated using a semi-batch reactor at different solid retention times (SRTs). The average pH values ranged from 0.91 to 1.2 at SRTs longer than 10 days, whereas the reduction of SRT to 4 days resulted in an increase in the pH value to about 2. The dissolution efficiencies of Al, ...

  • Particulate Control Strategies for Incineration

    Abstract This paper discusses various particulate emission control strategies that can be employed for Municipal Solid Waste (MSW), Municipal Sewage Sludge, and Industrial Waste Incineration facilities. An example will be given of a particulate control installation that successfully cleans off-gases from an incinerator at a large photographic products plant. Data supporting a theoretical ...


  • Sludge Incinerator RTO Upgrade with MLM-160-6®: $50,000+ Yearly Power Savings

    IntroductionThe city of Fitchburg, Massachusetts operates a multiple hearth incinerator that burns municipal sludge to minimize waste volumes. Although not universally used by municipalities in the United States, incineration is a widely accepted and used method of sludge disposal. The major benefit of incineration is a greatly reduced need for landfill space. An 85 - 95% volume reduction of ...

  • Overview of municipal sludge fluid bed incineration in North America – from green to greener – the Lakeview, the Duffin Creek and the Southerly experiences

    Thermal processes used in sludge disposal have become more attractive as process improvements have been introduced, such as power generation and efficient heat recovery. More and more utilities and agencies are reevaluating their sludge management practices to ensure that they are providing sustainable management solutions for their clients. The thermal process design approach to the disposal of ...

  • Volatility of heavy metals during incineration of tannery sludge in the presence of chlorides and phosphoric acid

    Knowledge of the behaviour of heavy metals in the combustion process is a most important factor in selecting disposal alternatives for waste materials. Accordingly, in this work, the vaporization behaviour of highly concentrated heavy metals (Pb, Zn, Cu and Cr) in tannery sludge were investigated experimentally. The sludge was spiked with various chlorine compounds (i.e. PVC, FeCl3, CaCl2 and ...

  • Thirty Years of Satisfactory Fluid Bed Sludge Incineration - The Northwest Bergen County Utilities Authority Experience

    ABSTRACT Fluid bed incineration has been used as a sludge disposal method at the Northwest Bergen County Utilities Authority since 1969 when the first incineration unit was installed. In 2000, the third generation plant became operational. Over this period, environmental regulations have changed, as have the State mandated air pollution control devices. Since the State mandated a wet ...

  • Characterisation of Incinerator Residues for Their Possible Re-Use

    MSW incineration produces a high quantity of residues (slags, fly ashes, sludges). Recycling suitability of residues is therefore an important issue requiring as a first step their physical and chemical characterisation (mass, granulometry distribution, merceology) and determination of their hazardousness (i.e. pollutant contents of heavy metals and chlorinated organic compounds). ...


  • Supercritical water oxidation presented as alternative to incineration – An update

    Environmentally benign waste disposal is becoming a more and more acute problem. A process now being commercialised, supercritical water oxidation is demonstrating extremely efficient organic waste destruction (99.99%) plus excellent environmental characteristics (none of the emissions associated with incineration). The process is especially suitable for the treatment of wastewater and sludges ...

  • A Comparison of Fluid Bed and Multiple Hearth Biosolids Incineration

    Abstract Incineration has been used as a disposal method for wastewater treatment biosolids for over sixty years. The first multiple hearth furnace for biosolids incineration was built in 1935 in Dearborn, MI. From that time through the late sixties, the multiple hearth was the thermal technique of choice for biosolids disposal. Today there are still some 150-175 aging multiple hearths in ...

  • Sustainable sludge handling for the 21st Century

    Purification of municipal and industrial waste waters leads to the generation of a residue-called “excess sludge”. This material when mechanically dewatered is typically 75-90% water. The balance of the dewatered sludge consists of organic compounds (solid waste, biomass) and inert materials (sand, salts, and metals). These sludges have been to date dehydrated to reduce the aqueous fraction using ...
