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 responsible ...

A STIEFEL project UTO Uvrier case study
The waste incineration plant UTO Uvrier is situated in the south western part of Switzerland. The Association which controls the plant was established in 1969 and treats waste from 44 municipalities with a combined population of 170,000 inhabitants. The principal task of UTO Uvrier is the thermal heat recovery from urban and industrial waste. Apart from this, UTO also treats other types of waste ...

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 ...

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 ...

EPA issues final rules for boilers
The U.S. Environmental Protection Agency (EPA) reports that more than 200,000 boilers, process heaters and incinerators will be impacted by a set of Clean Air Act regulations issued on February 21, 2011. Since EPA first proposed the Maximum Achievable Control Technology (MACT) rules in April 2010, several industry sectors have argued the costs of implementing the rules would pose an unreasonable ...

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 ...

The Other Side of Zirconium Oxide case study
Regular Fuel Efficiency Applications Separate Oxygen and Combustibles Sensors In standard flue gas applications for Thermox analyzers, the user generally tries to extract the maximum energy from the fuel and transfers as much of that energy as possible to the process. These applications require the process to be operated as efficiently as possible by keeping both oxygen (excess air) and ...

Analysis and Application of Sludge Low Temperature Heat Pump Drying Technology
Sludge is a by-product of the process of sewage treatment and water purification, and its main components include floccules composed of various microorganisms and organic and inorganic particles. The vast majority of sludge has the value of resource reuse. In 1995, the World Water Environment Federation (water environmental feder-action WEF) renamed the sludge as biosolids (biosolids), which is a ...

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 ...

New horizons for sludge
Increasing production worldwide, higher cost for disposal, tighter restriction sludge management solutions are in high demand. New technologies are rapidly multiplying, fueled as well by sludge’s potential as a source of energy and potential for phosphorus recycling. Several drivers are contributing to the need for sludge solutions. A global population of 7.5 billion ...

Solutions for sludge and biomass drying
Sludge is mostly water with some amounts of solid material removed from liquid sewage. Primary sludge includes settleable solids removed during primary treatment in primary clarifiers. Secondary sludge is sludge separated in secondary clarifiers that are used in secondary treatment bioreactors or processes using inorganic oxidizing agents. In intensive sewage treatment processes, the sludge ...

Comparison of phosphorus recovery from incineration and gasification sewage sludge ash
Incineration of sewage sludge is a common practice in many western countries. Gasification is an attractive option because of its high energy efficiency and flexibility in the usage of the produced gas. However, they both unavoidably produce sewage sludge ashes, a material that is rich in phosphorus, but which is commonly landfilled or used in construction materials. With current uncertainty ...
