  • Škvorec WWTP in Czech Republic - Case Study

    Client's voice Since we had installed VOLUTE Dewatering Press in our waste water treatment plant I realized how much time we were wasting using dewatering bags. VOLUTE doesn´t need my presence and works fully automatically. I don´t sometimes even know that there is a dewatering unit in operation. Dewatering Data Sludge Type: Waste ...

  • 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 ...

  • Ultra-small VOLUTE Dewatering Press ES-051 (Ukraine (1))

    In the year of 2004 in Ukraine, there was no compact sludge dewatering equipment suitable for small-scale wastewater treatment facilities like septic tanks. As for septic tanks, it had been common that sludge was disposed by tanker truck and sent to sludge dewatering facilities for post treatment. For that reason, the annual sludge disposal cost was extremely high, which had been a major issue ...

  • 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 ...

  • Sludge drying beds, Sarasota County, Florida - Case Study

    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 ...

  • Komagata Foods Co., Ltd. case study

    VOLUTE Dewatering Press reduces maintenance time sharply! Komagata Foods Co., Ltd., manufacturing feed for fish cultivation, used to use a belt filter press, but they had always faced clogging problems because of the oily sludge. They also suffered from spillage over from the side of filter cloth, making operators to keep their eyes on the machine all day. AMCON's ...

  • Operational strategy, economic and environmental performance of sludge treatment reed bed systems – based on 28 years of experience

    Sludge treatment reed bed (STRB) systems have been used for dewatering and mineralisation of sludge in Europe since 1988. STRB systems provide substantial environmental, economic, and operational benefits compared to mechanical sludge dewatering solutions such as belt presses and centrifuges. They require less energy, no chemicals, reduce the sludge volume and produce bio solids with dry solid ...

  • Geotube Dewatering Technology Helps Arizona Chemical Dewatering Technology Helps Arizona Chemical Solve “Tight Space” Challenge - Case Study

    Arizona Chemical Company, a Division of International Paper, converts terpenes, generated by cooking wood pulp for making paper, into resins used to make adhesrves. The plant's process waste of inorganic compounds (magnesium hydroxide, crude tall oil and fatty acids) is sent to an equalization basin (EQ) for storage and settling. The supematantis discharged into Panama City's wastewater treatment ...

  • Geotube Dewatering Technology Solves Lagoon Cleanout for Mexico’s Largest Chicken Processing Plant - Case Study

    Mexico's largest chicken processing plant was experiencing high levels of BOD discharge into the local river because their two sludge lagoons were full of high percentage solids sludge. The plant was expanding operations and had no place to store the additional sludge that would be generated, nor did it have any onsite means of removal and dewatering. The problem was compounded because the excess ...

  • Dewatering project in Almeirim (Portugal) - case study

    TenCate Geosynthetics has supplied TenCate Geotube® containers for a dewatering project in Almeirim (Portugal), which involves the removal and dewatering of organic sludge. This first project in Portugal is the result of cooperation between TenCate Geosynthetics, Ashland Hercules Water Technologies and Geosin, the local partner. TenCate Geosynthetics and Ashland Hercules Water Technologies ...

  • Sustainable sludge handling for the 21st Century

    Purification of municipal and industrial waste waters leads to the generation of a residue-called “excess sludge”. This material when mechanically dewatered is typically 75-90% water. The balance of the dewatered sludge consists of organic compounds (solid waste, biomass) and inert materials (sand, salts, and metals). These sludges have been to date dehydrated to reduce the aqueous fraction using ...

  • Municipal WWTP Digester Cleanout - Cambridge, Ohio (Wastewater Treatment) - Case Study

    THE CHALLENGE Cambridge, OH is a small town of 13,000 residents. Tim Wheatley, Superintendent of the Water Pollution Control Center operates a 3 MGD activated sludge plant at about 80% of its capacity. The plant recently switched from anaerobic digesters to an aerobic digester. They had been dewatering Iheir sludge on four vacuum assisted drying beds housed in a large shed. Alternatively, ...

  • Septic Tank for Commercial Building (Ukraine (2))

    As for this septic tank, thickened sludge had been pumped to a tanker truck for disposal 2-3 times a month. However, there had been longstanding concerns confronted by the end user. Their concerns were not only the high sludge disposal cost but also the odor which comes along with the presence of a tanker truck. They had looked for a suitable sludge dewatering unit for small-scale wastewater ...

  • Cellulose recovery from municipal wastewater

    During Aquatech 2015 the Dutch technology developer Brightwork set in the spotlight the recovery of cellulose from waste water. The project Cellulose Assisted Dewatering of Sludge (CADoS) aims at separating cellulose fibres from toilet paper from waste water using finescreening technology. After separation the fibres serve as a filter aid for effective dewatering of biological sludge. The ...

  • An analysis of the environmental management elements related to the improvements of the drying kinetics of waste activated sludge by Fenton peroxidation

    Advanced sludge treatment processes (AST) reduce the amount of sludge produced and improve the dewaterability, thus probably also affecting the heat transfer properties and the drying characteristics of the sludge. This paper studies the influence of the Fenton peroxidation on the thermal conductivity of the sludge. Results demonstrate that the Fenton's peroxidation improves the sludge cake ...

    Sewage sludge is a by-product generated from municipal wastewater treatment (WWT) processes. This study examines the conversion of sludge via energy recovery from gasification/combustion for thermal treatment of dewatered sludge. The present analysis is based on a chemical equilibrium model of thermal conversion of previously dewatered sludge with moisture content of 60–80%. Prior to ...
