  • A New, Real Technology for Solids Dewatering

    Over the past decade, there have been few significant improvements to the performance in sludge dewatering technologies. Most improvements, other than process optimizations from the polymer industry, have been minor adaptations to the various dewatering technologies such as adding additional pressure rollers or modifying the diameters of pressure rollers on a belt filter press. The adoption of ...

  • 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 ...

  • 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 ...

  • Wastewater-Solids Dewatering Odor Control - Case Study

    Background The Milan Wastewater Treatment Plant, located just south of Moline, Illinois, is a 1.7 MGD (6,434 m3/day) activated sludge facility with an average wastewater flow of 700,000 gpd to 800,000 gpd. This facility dewaters primary sludge using a belt filter press (Figure 1). The press operates an average of three times per month, 8 hours per day at a pump rate of 100 gpm. The ...

    YEAR: 2009 COUNTRY: BELGIUM N° and MACHINERY MODEL EMPLOYED: 12  GHT 2000.P19 MEM Diemme® Filtration In Antwerp Harbour, lots of sediment accumulates, equal to 600,000 tons of dry material, which caused a gradual decrease in depth with the consequent reduction in navigability. Since a few years ago, the ...

  • Sludge drying beds, Sarasota County, Florida

    Dewatering sludge at wastewater treatment plants has traditionally been a major operational concern. Most large operations must use mechanical filter presses or centrifuges to efficiently dewater their sludge. For many smaller operations, however, this equipment is too expensive and too large for their needs. Therefore, many smaller facilities rely on the sand filter drying beds for sludge ...

  • Souderton looks at viability of investment in sludge dryer

    Despite the day's snowy weather, the Souderton Borough Council met for a brief session March 2 and discussed the newest option for the borough's sludge removal. The borough has been looking for a device to dewater the sludge produced by the in-town treatment facility for nearly two years. Removing the water would allow the borough to apply the sludge to land, which would save on hauling costs. ...

  • You can dewater your cake and pump it too! Conveyance options for OCSD Plant 1

    OCSD is currently upgrading Reclamation Plant 1 to co-thicken primary and waste activated solids using centrifuges. Digested solids will also be dewatered using centrifuges and the two processes will be housed in the same building. A small building footprint, stringent redundancy requirements, and a 200 foot distance between the dewatering and storage facilities requires innovative engineering ...

  • Addressing digester foaming by fixing activated sludge system and gaining capacity in both

    The City of Richland Wastewater Treatment Facility digesters have experienced Nocardiainduced digester foaming problems from the time they went into operation in 1985. Because of the persistent foam, most or all of the thickened waste activated sludge (TWAS) was often not sent to the digesters but directly to the belt filter press to be dewatered separately from the digested sludge. It was ...
