Dwr Cymru Welsh Water delivers AD plants early, and moves towards power self-sufficiancy in wastewater management
The development and delivery of Advanced Digestion plants at both Cardiff and Afan WwTWs is at the core of this strategy. These sites alone will process 50,000tDS/y using Cambi Thermal Hydrolysis plants and new digesters. This sustainable approach to sludge treatment has been encouraged and supported by Welsh Assembly Government, Regulators, local planning departments and local communities.
Design, construction and delivery
Full construction and delivery of the Cardiff and Afan schemes was required by April 2011 to maximise the Renewables Obligation Certificate (ROC) benefits, and minimise costs to customers. Imtech Process was selected for the delivery of the process and M&E engineering work, working collaboratively with Morgan Sindall, the civil design and construction partner. A full technical and commercial assessment of available technologies was undertaken with DCWW. The most economic solution for these applications was Cambi Thermal Hydrolysis, due to the very high levels of secondary sludges. The Thermal Hydrolysis option was selected for Cardiff and Afan schemes for the following reasons:
