Under
the European Urban Waste Water Treatment Directive, Northumbrian Water
developed the Bran Sands site to provide additional treatment for
effluents from its existing treatments works of the surrounding areas.
The site incorporates one of the largest sludge drying facilities in
Europe.
Effluent Treatment
Works
The Works has been designed to
treat a flow of up to 260,000 cubic metres/day and a load of up to 140
Tonnes of biochemical oxygen demand (BOD)/day of industrial and
municipal waste water. This is equivalent to a population of
over 3.5 million.
Regional Sludge Treatment
Centre
The
Regional Sludge Treatment Centre (RSTC) takes sewage sludge directly
from the Effluent Treatment Works along with sludge imported by ship,
road tanker and pipeline from the Northumbrian Water region. The
sewage is processed, dried and pressed into pellets. The centre
will produce over 90,000 tonnes of biopellets per year.
Power Generation
Gas Turbines are used to
generate heat for the drying facilities and electricity for use on the
site as a whole. The electricity generation capacity of
the plant should be 15MW by completion of the plant.
Scope and Solution
As a mission critical project
and being one of their most significant investments (>£200 million)
Northumbrian Water Ltd awarded Aston Dane plc the contract for the
integration of the PLC and SCADA software for the site.
Valued at close to £1million
