  • 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 ...

  • On the removal of silver and antimony radionuclides from radioactive liquid waste by some classical means

    After partial upgrading of a research reactor at the Pakistan Institute of Nuclear Science and Technology, Islamabad, some waste effluents having 110mAg and 124Sb with higher activity levels than the disposal limits piled up because the waste storage capacity was not yet enhanced. Experimental work was conducted to arrive at some optimum procedure for the treatment of the waste to ensure smooth ...

  • Recycle of waste backwash water in ultrafiltration drinking water treatment processes

    In drinking water treatment, ultrafiltration (UF) membrane systems are generally operated at 90 to 95% recovery with production losses resulting from waste residual streams such as backwash water and clean-in-place (CIP) liquid residuals. In drought-prone regions, it may be desirable to apply alternative UF plant design configurations to increase recovery rates and minimize water loss. This ...

  • CH#830 - Bioaugmentation Improves Performance of Brewery Waste Treatment Plant

    Introduction This packaging plant finishes 'heavy' beer, a liquid concentrate, into the well-known canned and bottled products. The plant handles 50,000 barrels per week and generates over 350,000 gallons of wastewater per day. Wastes are treated at the plant's 0.5 MGD waste treatment facility which operates under a standard discharge NPDES permit. Waste beer is the main constituent of ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of. Wastewater treatment is a multi-stage process to renew wastewater before it is discharged to the municipal sewer system. The goal is tio reduce or remove organic ...

  • Landfill leachate treatment

    Landfills are categorized by regulations in three types: industrial, municipal, and hazardous. Individual landfills may be further differentiated by the types of waste which they accept. All landfills are required to be capped, usually occurring at the end of each day. The cap is typically 6-8” of soil. The cap reduces odor and loss due to wind. At the closing of the landfill, a permanent ...

  • 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. ...

  • Wastewater Treatment Process

    The wastewater treatment process is complex and critical to civilization. In simplest terms, wastewater is water that has been mixed with waste matter. Wastewater can be classified as domestic, municipal, or industrial based upon the source of generation. For instance, domestic wastewater comes from everyday liquid waste, including water used to flush the toilet, to shower, or to wash dishes. ...

  • Treatment of ship sludge oil using a plasma arc waste Destruction system (PAWDS)

    The Plasma Arc Waste Destruction system (PAWDS) uses a plasma torch to quickly gasify solid  waste on board ships. Developed under the support of the US Navy, this compact one deck system has been in commercial operation on board a cruise ship for more than three years. With the support of Carnival Cruise Lines and the National Research Council of Canada, the PAWDS was recently modified in ...

  • Presence and survival of fungi and clostridium Tyrobutyricum during anaerobic treatment of organic household waste

    Today the anaerobic microbial process of biogas formation is more into focus than ever. This interest is due to the fact that is offers the community means of fulfilling several obligations: treatment of organic wastes, recirculation of nutrients between urban and rural areas and production of renewable energy. Presently, several Swedish cities have built centralised biogas plants, treating ...

  • Wastewater Treatment & Recycle

    Fresh water is a scarce commodity; this fact is well acknowledged by one and all. People at all levels be it general public, governmental bodies, and industries understand the implications of good quality water availability in terms of quantity, cost and wastage. As a consequence, there is a growing consensus on wastewater treatment for recycle/reuse. This paper briefly describes the treatment ...

  • 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 ...

  • Wastewater-Primary Treatment

    Primary Treatment is defined as a wastewater treatment process that takes place in a rectangular or circular tank and allows those substances in wastewater that readily settle or float to be separated from the water being treated. This process achieves solids separation. The solids readily available to settle to achieve sedimentation will do so in a settling tank referred as a clarifier. On the ...

  • Use of earthworms (Eisenia fetida) and vermicompost in the processing and safe management of hazardous solid and liquid wastes with high metal contents

    Two feasibility studies using the earthworm (Eisenia fetida) and vermicompost in the processing and remediation of solid and liquid wastes with high metal content are presented: vermicompost as adsorbent substrate for remediation of wastewaters contaminated with metals; earthworms for remediation of arsenic (As) and mercury (Hg) in landfill soils. The feasibility of vermicompost for the ...
