  • Biosolids Minimization using Integrated Alkaline Sludge Hydrolysis and Biological Nutrient Removal Process

     ABSTRACT This paper presents a pilot-scale evaluation of an integrated approach to sludge management utilizing a combination of biological nutrient removal and biosolids alkaline hydrolysis, as well as attempts to explore the impact of recycled alkaline hydrolysates on sludge yield and anaerobic digestion. The novel concept of converting an existing conventional activated sludge (CAS) ...

  • 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 ...

  • 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 ...

  • Rotomite application serving municipal WWTP, Decatur, Arkansas-case study

    As reported in WaterWorld, Serving the Municipal Water/Wastewater Industry In 1996, the Town of Decaur, Ark., purchased a self-propelled Rotomite 180-P dredging system as part of a new biosolids management program designed to reduce the cost of sludge disposal and to increase solids detention time in-plant. While less than 1,000 people live in Decatur, the town's wastewater treatment plant ...

  • Pressure-loss computation procedures for non-Newtonian pipe flow

    Wastewater sludge with solids concentrations above about 2 percent exhibit non-Newtonian behavior, i.e., the sludge apparent viscosity changes with the shear rate (flow velocity). To determine pipeline head loss for sludge streams to and from anaerobic digesters, samples of primary, secondary and digested sludge were collected from Orange County Sanitation District Plant No. 1 and analyzed to ...

  • Springfield - Case Study

    At Their Disposal Komline-Sanderson minimizes solid waste disposal costs in Springfield, Mass The City of Springfield, Mass., currently uses a contract composting facility, which is located at the 65 MGD Bondi Island Wastewater Treatment Plant to dispose of their solid waste.

  • Operating experience of Aberdeen CAMBI thermal hydrolysis plant 2002

    Introduction This paper reviews the establishment of a new 50 dry tonne per day biosolids processing facility at a green field site at Nigg Bay, Aberdeen Scotland. Prior to 2001 all sewage had been pumped by long sea outfall into the North Sea. Consequently there was only a minor biosolids operation in the area dealing only with small, rural works. Proposals were sought from a number of ...
