  • A review on sludge dewatering indices

    Dewatering of sludge from sewage treatment plants is proving to be a significant challenge due to the large amounts of residual sludges generated annually. In recent years, research and development have focused on improving the dewatering process in order to reduce subsequent costs of sludge management and transport. To achieve this goal, it is necessary to establish reliable indices that ...

  • 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 ...

  • Geotube Dewatering for Lagoon Sludge - Case Study

    Background In many animal waste management schemes it is desirable to separate solids from waste water and/or manures. In cooperation with the Department of Animal and Dairy Science, animal waste specialists from Biological and Agricultural Engineering are field testing a technology new to agriculture, to remove solids from lagoons. The test is currently being conducted at the UGA Dairy ...

  • 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 ...

  • 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 ...

  • 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 ...

  • Identifying energy and carbon footprint optimization potentials of a sludge treatment line with Life Cycle Assessment

    This study exemplifies the use of Life Cycle Assessment (LCA) as a tool to quantify the environmental impacts of processes for wastewater treatment. In a case study, the sludge treatment line of a large wastewater treatment plant (WWTP) is analysed in terms of cumulative energy demand and the emission of greenhouse gases (carbon footprint). Sludge treatment consists of anaerobic digestion, ...

  • Pyrobustor - A Proven,Small-Scale, Biosolids-to-Energy Solution

    27 municipalities in southern Germany set up a special-purpose entity called KSV GmbH for the specific purpose of disposing regional sewage sludge. The goals of this project were two-fold; eliminate the expensive cost of transporting sewage sludge over long distances and avoid incalculable costs by outsourcing sludge disposal. To achieve this, KSV GmbH installed the Pyrobustor® at the ...
