  • 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 ...

  • 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 ...

  • Dewatering of Industrial Sludge - Case Study

    At Ten Cate Protect, town of Nijverdal, The Netherlands, 2006 During the wastewater treatment process at Ten Cate Protect large quantities of sewage sludge are liberated. A couple of days per week this sludge is transported in tanker trucks to a waste disposal plant. On June 14th 2005 a Geotube MDS unit was put in operation at Ten Cate Protect to separate and condense the sludge of the aerobic ...

  • Sewage sludge and waterworks sludge stabilization in sludge treatment reed bed systems

    In this study, results about sludge stabilization in sludge treatment reed bed (STRB) systems in two different systems, Hanningfield STRB 1 (England), treating waterworks sludge, and Stenlille STRB 2 (Denmark), treating surplus activated sludge, are presented. The study mainly focused on the effectiveness of the STRBs systems in stabilizing sludge organic matter; in fact, parameters correlated ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Economic assessment of sludge handling and environmental impact of sludge treatment in a reed bed system

    The effect on the environment of the establishment and operation of a sludge treatment reed bed system (STRB) is quite limited compared to mechanical sludge dewatering, with its accompanying use of energy and chemicals. The assessment presented here of the investment, operation and maintenance costs of a typical STRB, and of the related environmental impact, is based on the experiences gained ...

  • Gas composition of sludge residue profiles in a sludge treatment reed bed between loadings

    Treatment of sludge in sludge treatment reed bed systems includes dewatering and mineralization. The mineralization process, which is driven by microorganisms, produces different gas species as by-products. The pore space composition of the gas species provides useful information on the biological processes occurring in the sludge residue. In this study, we measured the change in composition ...
