  • 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 ...

  • Village of Maybrook, NY Sludge Dewatering System

    Project Summary: The Village of Maybrook WWTP process consists of primary clarification, trickling filters, and secondary clarification. Primary sludge and trickling filter humus is anaerobically digested. The belt filter press dewaters the sludge eliminating the need for sludge drying beds. The belt filter press discharge cake solids are consistently in the 25 to 30 percent range, which is ...

  • 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 ...

  • Sludge Dewatering Performance - A Survey Of Real Operational Performance

    Abstract. A survey of the literature revealed that it is difficult, indeed virtually impossible, to get meaningful information about the likely performance of dewatering equipment. As a consequence customers have sometimes specified impossible target  performances and suppliers have unwisely agreed to them. Dewatering has major consequences for downstream processes, for example sizing dryers ...

  • The Importance of Dewatering

    With spring comes two things: the onset of construction season for most of our country and rain- lots and lots of rain. The unpredictability of storms and the amount of rainfall is all a guessing game.  Jobsites flood, work stalls and projects get delayed. Rain makes it hard to keep dry and on-schedule. What’s the solution? Dewatering is a technique used to control ...

  • Dewatering sludge, coming from the cellar of the Rijksmuseum with Geotube - Case Study

    Foreword: In 1885, the first National Museum of Holland opened its doors in Amsterdam. The architect Cuypers designed the building in a mixture of both Gothic and Renaissance styles. Since the opening, the original building has been extended by the construction of new wings, and changes have been made to Cuypers' original design. An ongoing project to restore the Rijksmuseum ...

  • Full scale optimisation of sludge dewatering and phosphate removal at Harnaschpolder wwtp (The Hague, NL)

    At Harnaschpolder wwtp phosphate removal from wastewater and sludge dewatering is optimised by dosing magnesium hydroxide to digested sludge. To optimise sludge dewatering and phosphate removal, a full-scale test has been executed since August 2015 using temporary equipment. In this test magnesium hydroxide is added to the digested sludge buffer. Significant positive results are achieved. An ...

  • 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 ...

  • 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 ...

  • CORK, Ireland: INNODRY 2E®–Complete sludge treatment solution including dewatering, drying and granulate storage

    Cork WWP (Ireland) was designed in 2000. The specifications did require a complete sludge treatment solution including dewatering, drying and granulate storage. The system was to take maximum advantage of the biogas produced by digesters as well as any surplus heat used for the heating of the digesters. The drying equipment had to be flexible in order to cover the varying production rates and, at ...

  • Combined experiences of thermal hydrolysis and anaerobic digestion – latest thinking on thermal hydrolysis of secondary sludge only for optimum dewatering and digestion.

    ABSTRACT The basic principles of batch thermal hydrolysis process (THP) are well known as a pre-treatment to anaerobic digestion (AD) . Early work done in the 70s in the USA and the 80s in Japan demonstrated the optimum time and temperature for thermal hydrolysis being 340 F for 30minutes. These principles have been put into full practice in 20 plants around the world at plants ranging from 5 ...

  • Technical Focus: Sludge Blanket

    Regardless of treatment process, sludge blanket control is an important aspect of any wastewater treatment plant, and correct monitoring and treatment of sludge is paramount for efficiency and cost control. Manual monitoring of sludge blanket levels is an occasional and often rushed method of control and can lead to inaccuracies being compounded over time, potentially leading to overspill into ...

  • 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 ...

  • Direct Dewatering from Oxidation Ditch (Africa)

    Development of proper sanitation or wastewater treatment has been a critical issue in Africa for prevention of almost any types of infectious diseases. Generally, anywhere in the world, the keys for the successful wastewater treatment system is choosing the appropriate solids removal and dewatering technology and achieving the acceptable quality of water for discharge. However, the high ...
