  • New processes for the improvement of sludge digestion and sludge dewatering

    INTRODUCTIONThe examination of numerous sewage sludges from municipal wastewater treatment plants leads to the conclusion that on the one hand dewaterability of these sludges worsens and that on the other hand dewaterability of sludges becomes more and more important due to increasing disposal costs. Especially wastewater treatment plants with inflows from the food processing industry often face ...

  • Nitrification of centrate from dewatering of anaerobically digested sludge

    Nitrification of anaerobically digested sludge centrate was studied in bench-scale suspended growth and fixed film enhanced suspended growth systems at temperatures of 10.5-28.5°C and pH values of 6.0-9.1. Nitrification followed zero-order kinetics in both systems, and ammonia removals in excess of 99% were observed. The temperature dependency of the suspended growth nitrification rate ...

  • Processing Wastewater Sludge Using Dewatering Containers

    The relative cost of dewatering equipment varies widely and is directly related to the processing rate. For smaller utilities that need to dewater sludge in batches, dewatering containers are an alternative that can be relatively inexpensive and simple when compared to other technologies on the market. The most common type of dewatering container is based on a roll-off box design, although any ...

  • Dewatering sludge originating in water treatment works in reed bed systems

    The dewatering process of the liquid water works sludge was examined in a trial with a series of six trial beds, each 20 m2. These were monitored from April 2008 to June 2010. It is possible to get the vegetation to grow in ferric sludge (∼300,000 mg Fe/kg dry solid, pH 7,7). It has not been necessary to use fertilizer. The influence of the loading programs (15–50 kg dry solid/m2/year) was tested ...

  • Pulp & Paper Water Treatment - A look at optimizing water resource management

    Application Case Study (Pulp/Paper Operations) The pulp and paper industry has traditionally been a consumer of large amounts of fresh water and power. Recently, increased focus has been given to the optimized efficiency of paper mills and to the environmental sustainability footprint of the industry. Therefore, water resource management has become a more critical factor ...

  • Dewatering Paper Mill Lagoon Sludge - Ancram, NY - Case Study

    Sludge from the secondary treatment system lagoon at the New York mill of Schweitzer-Mauduit International, Inc. had to be removed. Geotube technology with SmartFeed Chemical Conditioning System supporting technology was the most cost-effective and  efficient method  of containing  and dewatering the sludge. The dredging contractor removed 3,285 cubic yards of sludge from the ...

  • Process-based modelling of phosphorus removal in a novel constructed wetland system using dewatered alum-sludge as substrate

    A process-based model that can evaluate the transport and the fate of phosphorus (P) in agricultural wastewater was developed for a novel 4-stage dewatered alum sludge cakes (DASC) based constructed wetlands (CWs) system using STELLA software (version 9.1.4). The model considered adsorption, plant and microbial uptakes as the major forms of P involved in the transformation chains. The results ...

  • Advanced Dewatering & Drying System – A Performance Model

    Since the beginning of 2006, an advanced dewatering and drying system has been operating in the United Kingdom. The facility is producing greater than 40 dry metric tonnes per day of enhanced biosolids in accordance with European Union regulations. The facility is producing biosolids with pathogen levels near minimum detectable levels. This is being achieved with an energy usage less than the ...

  • Pulp & Paper Sludge Dewatering - Stora Enso, Niagara Mill, Wisconsin - Case Study

    The Stora Enso, Niagara Mill, was established in 1889. Niagara Mill uses 7,500,000 gallons per day of water from the river to make pulp & paper. The removal of the solids is accomplished by treating it with alum, then a flocculent, allowing the solids to settle out in a 2,000,000 gallon setting tank system. This tank requires yearly cleaning to ensure quality water for the paper making ...

  • Vertical-flow constructed wetlands as an emerging solution for faecal sludge dewatering in developing countries

    Yard-scale experiments aiming at assessing the suitability of vertical-flow constructed wetlands to dewater faecal sludge (FS) were conducted in Yaoundé (Cameroon). During 6 months, beds vegetated either with Cyperus papyrus L. or Echinochloa pyramidalis (Lam.) Hitchc. & Chase were fed under constant solids loading rates (SLR) of 100, 200 and 300 kg TS (total solids) m−2/year. ...

  • Environmental sludge treatment

    During the process of wastewater treatment, sludge generation is an important and at times crucial issue to be addressed as inadequate sludge handling system can pose serious environmental implications. Liquid sludge can be easily thickened and reduced to a solid cake via sludge thickening / dewatering. This reduces the volume of liquid sludge significantly, usually resulting in a quite ...
