  • Controlling Sludge in Lamella Clarifiers

    This month we are focusing on the control of sludge blanket build up in Lamella Clarifiers. Lamella Clarifiers, also known as Inclined Plate Separators (IPS) are in common use at Waste Water Treatment Sites as small footprint plant settlement units and are often employed in ...

  • Biotreatment of Odors from the Zimpro Sludge Conditioning Process

    Management of odor emissions generated during thermal sludge conditioning is a well known disadvantage of the “Zimpro” process. Traditional methods of using chemical oxidation and high temperature destruction result in the formation of secondary products, such as chlorine gas, organic halocarbons or nitrogen oxides. In this study, biotrickling filter technology was evaluated at the Villa Hills ...

  • Treatment of Sludge Return Liquors: Experiences from the Operation of Full-Scale Plants

    ABSTRACTMore stringent effluent criteria with regard to nitrogen call for improved nutrient removal techniques in wastewater treatment plants (WWTPs). Besides optimisation of the liquid treatment train of the plants, over the last years, attention has increasinly centred on the problem of return flows from sludge treatment. Depending on sludge handling and treatment, some 15 to 25 % of the ...

  • A short-term investigation using In-situ ammonia monitoring at a WWT, M Keown Severn Trent Water

    Summary: Two separate inlet streams are received for treatment at this works, one being predominantly domestic in origin and the other being predominantly industrial, arising from a local dye works. Their treatment is kept completely separate with municipal stream being subject to preliminary treatment, primary settlement, and secondary treatment in surface aerated activated sludge ...

  • Technical Focus: Turbidity as Control for Primary Settlement

    Turbidity is a very useful tool when regarding control within the primary settlement stage of water treatment. By utilising turbidity as a control variable during this stage of the process you  can enable a more rapid response to variations in load  and provide early warning  to operators of equipment malfunction before it’s too late; allowing for immediate action to be taken ...

  • Sequencing batch reactor

    Sequencing batch reactors (SBR) sequential batch reactors are industrial processing tanks for the treatment of wastewater. SBR reactors treat waste water such as sewage or output from anaerobic digesters or mechanical biological treatment facilities in batches. Oxygen is bubbled through the waste water to reduce biochemical oxygen demand (BOD) and chemical oxygen demand (COD) to make suitable for ...

  • French vertical-flow constructed wetland design: adaptations for tropical climates

    The French Outermost Regions are under tropical climate yet still have to comply with both French and EU regulations. French vertical-flow constructed wetland systems appear well adapted to the technical specifics of these regions but their adaptation to tropical climate requires new design guidelines to be defined (area needed, number of filters, type of plants, material to be used, etc.). A ...

  • Wireless Pakscan controls the flow at Nevada gold mine

    A gold mine in Nevada USA has been able to take advantage of wireless Pakscan digital control for newly installed IQ intelligent electric valve actuators on the water filtration plant. The Newmont underground mine utilises Geotube® dewatering technology to separate sediment from both ground and extraction process water. The filter systems, which are installed above ground, are fabricated from ...

  • Solving waste oil management and removal problems in power generating plants

    If your plant is like most, it is doing a good job of preventing oily water waste and waste oils from escaping into the environment. But at what cost? As labor resources dwindle, operating and maintaining drainage systems, oil separators, and sometimes inadequate oil removal equipment is expensive. Paying higher than needed costs for waste oil disposal, filtration and water treatment due to these ...

  • Reducing Odor and VOC Emissions

    The Montgomery County Regional Composting Facility (MCRCF) in Silver Spring, Maryland is designed to process 400 wet tons/day of lime amended biosolids from the Blue Plains Wastewater Treatment Plant (WWTP) in Washington, D.C. Recently, political pressures forced operations to cease at the MCRCF. Although the aerated static pile composting plant’s fate has not been completely decided, its owner, ...
