  • Development of wet pre-treatment and pulper technology

    Since 1984 BTA is involved in activities in the area of waste pre-treatment. This process was first implemented in 1986 in a pilot plant. The patented BTA-Process is consisting of the following main steps: - Wet pre-treatment of waste with separation of the contaminants and production of a pumpable suspension- Sand separation by a hydrodynamic grit removal system- Digestion of the suspension in ...

  • High frequency monitoring needed to protect UK rivers - Case Study

    The science behind nutrient pollution in rivers is still poorly understood despite the fact that nitrate and phosphate concentrations in the UK’s rivers are mostly unacceptable, although an element of uncertainty exists about what an acceptable level actually is. Key to improving our understanding of the sources and impacts of nutrient pollution is high-resolution monitoring across a broad ...

  • Electrochemical decomposition of fluorinated wetting agents in plating industry waste water

    Electrochemical decomposition of fluorinated surfactants (PFAS, perfluorinated alkyl substances) used in the plating industry was analyzed and the decomposition process parameters optimized at the laboratory scale and production scale of a 500-liter reactor using lead electrodes. The method and system was successfully demonstrated under production conditions to treat PFAS) with up to 99% ...

  • The Flushability of Flushable Wet Wipes

    Whether used to remove cosmetics, clean a baby or wipe food and debris from the kitchen counter, a growing number of consumers are purchasing flushable wet wipes for their household needs. In fact, The Atlantic reported personal wet wipe sales reached an estimated $2.2 billion last year, and Euromonitor International’s market tracker predicts 3-percent growth in sales volume of wet ...

  • Waste Disposal

    Introduction The final step in the waste management process is waste disposal, the permanent isolation of waste. Some wastes can be managed and disposed safely with existing facilities and proven methods. Other Department of Energy (DOE) wastes require more complex disposal facilities. DOE has conducted extensive research into alternative waste disposal methods and has concluded that deep ...

  • Industrial wastewater treatment

    Industrial wastewater treatment covers the mechanisms and processes used to treat waters that have been contaminated in some way by anthropogenic industrial or commercial activities prior to its release into the environment or its re-use. Most industries produce some wet waste although recent trends in the ...

  • Process auditing and performance improvement in a mixed wastewater–aqueous waste treatment plant

    The wastewater treatment process is based on complex chemical, physical and biological mechanisms that are closely interconnected. The efficiency of the system (which depends on compliance with national regulations on wastewater quality) can be achieved through the use of tools such as monitoring, that is the detection of parameters that allow the continuous interpretation of the current ...

  • Thermal Treatment Technologies

    Hot gas decontamination: Hot gas decontamination is a technology still in the pilot-scale of development that can be used for decontamination of explosives-contaminated masonry or metallic structures. The method involves sealing and insulating the structures, heating with hot gas stream to 260 °C (500 °F) for a prescribed period of time, volatilizing the explosive contaminants, and destroying ...

  • Dry/Wet Scrubbers for Clean Air Compliance

    Air-scrubbing venturis and towers may be the answer to clean air compliance for small- to medium-sized companies. Forthcoming requirements of the Clean Air Act Amendments of 1990 will inventory many more specific chemicals considered hazardous. From acetaldehyde to xylenes, the list regulated under the air taxies program includes 189 hazardous air pollutants (HAPs). That number may ...

  • Sewage Pump - Klargester is the market leader for small and medium-sized domestic treatment plant and waste water treatment systems in the UK

    There are a variety of solutions on the market for properties in the UK that are unable to connect to the main sewer by gravity. However, UK building regulations dictate that pumping stations must be used whenever possible. As a result, pumping stations are the most commonly specified solutions for off-mains developments, ahead of sewage treatment plants, such as the Biodisc, and septic tanks. ...

  • Waste Management Overview

    Introduction Our Nation has entered an era in which, as a result of changing world conditions, nuclear weapons production is receiving less attention while the public is expressing increasing concern about protecting human health and preserving the quality of our environment. In response to this national concern, the Department of Energy (DOE) has made waste cleanup and environmental restoration ...

  • The myth of `residual waste`

    Recently, I was asked by my good friend John Nicholson (a consultant and contributing editor to this magazine) to address a meeting of the Air and Waste Management Association (AWMA) Ontario Sector, regarding my position on generating energy from 'residual waste.' This invitation provided me with the opportunity to research the composition of so-called residual waste -- you know, the roughly 35 ...

  • Wet electrostatic precipitators: A preferred technology for emission control

    The basic science behind electrostatic precipitators is as familiar and as simple as static cling. But today, this elemental force has been harnessed to a technology that is helping to remove millions of tons of toxic chemicals from our atmosphere; saving billions of dollars annually in pollution-related physical damage; and averting costly impacts on health and mortality rates for millions of ...

  • Remscheid pilot project: evaluation of a large scale trial of utilizing biodegradable waste bags for biowaste collection and treatment

    Separate collection of organic waste may be considered as an integral part of contemporary waste management schemes. In this function it became widely accepted in the last ten years. It pursues the idea of a recycling economy according to the European hierarchy of waste - prevent, reduce, recycle - and is aimed at closing nutrient cycles. Nevertheless, separate collection at source essentially ...

  • The biological basis of wastewater treatment

    Introduction This booklet was written to fulfil the need for a simple explanation of the biological processes that underpin wastewater treatment. It attempts to show how the bacteria involved deal with the organic carbon in the sewage. Remarkably, there are just 3 major processes involved, and these mirror exactly the 3 major processes at work in the plant viz: biodegradation, oxygen ...
