Online PR News – 15-July-2012 – Bedfordshire – CTM Systems have been awarded the Contract for the design, supply, installation and commissioning of a 160m3 sludge cake storage and lorry loading system for Barnhurst STW for Severn Trent / JN Bentley Limited.
Barnhurst STW is located outside Wolverhampton, and serves an existing population
of 148,000, which is most of Wolverhampton. Currently, the cake is dewatered to just 18% and stored within an existing silo. Due to handling constraints, this low level of cake dry solids, does not achieve the desired stackability required at the farm at which the cake is recycled.
CTM Systems say the project will significantly improve the handle ability of the cake biomass.
It is proposed to provide three centrifuges (two new and one of the existing centrifuges) at a location outside the existing centrifuge building to enable construction and commissioning without interrupting the cake production and transportation. The new dewatering system will provide cake at 25%. A new silo is proposed to replace the two existing cake silos, which will be decommissioned.
The new CTM Silo storage system will be of low height design, to comply with operational constraints on the site. The Silo will be located downstream of the proposed centrifuges. A new lorry loading area will also be provided.
A flexible system, giving plant redundancy is provided for the benefit of Severn Trent Operations, by the provision of multiple CTM discharge Live Bottom Screws and two independent lorry loading CTM belt conveyors, each rated at 68m3/hr.
Access platforms and silo mounted instruments are also provided under the Contract.
The equipment is due for installation during May 2012 and it is anticipated that commissioning of the system will take place in October 2012.
