64 cbm intermediate storage for de-watered sludge at the Hartlepool (GB) location

For our English partner AGRIVIERT we developed a compact piling container for de-watered sludge which, as part of the overall logistical concept, decisively increased the cost-effectiveness and hygiene of sludge disposal in the sewage treatment plants of smaller cities in northern England. Open sludge storage sites or containers with their corresponding odour and hygiene problems are now a thing of the past.

Our partners set the following requirements, amongst others, for the system:

  • Closed construction
  • Easy connection to upstream centrifuges or chamber filter presses
  • Reliable, robust technology
  • Shortest installation times and simple dismantling for location change
  • Compact design for uncomplicated integration into existing systems
  • High utilisation of available volume
  • Minimised downtimes for transport vehicles thanks to high discharge capacities
  • Fully automatic operation along with the simplest operation
  • Fulfilment of the stringent requirements of the English water management authorities

Integrated weighing in association with automation facilitate a decentralised request for the amounts of sludge accruing in the individual plants, ensuring optimal disposition of vehicles for removal of the dewatered sludge. In certain plants, an on-demand function of the controls ensures the automatic generation of a request for a transport vehicle once a previously set limit value is reached.

This concept has proven to be so convincing that over the ensuing period, additional plants were equipped in the same fashion and integrated into the logistical concept.

The system represented here was realised in Hartlepool as the first in a series of systems and since then, has reliably carried out its service.

Technical key data:

  • Volume: approx. 64 cbm
  • Sludge piling volume: approx. 60 cbm
  • Discharge capacity: approx. 2 * 25 t/h - 30 t/h = 60 t/h
  • Transport vehicle loading time: approx. 20 - 25 min
