Monsal awarded new advanced digestion contract for Wessex Water
ADBA MEMBER PRESS RELEASE
ADBA member Monsal has been awarded the contract to supply its advanced digestion process, to Wessex Water via MWH Contracting for a new digestion project at Trowbridge.
Monsal will supply its enzymic hydrolysis technology for the treatment of sewage sludge at the Trowbridge site. The plant will process 10,000 dry tonnes of sludge per annum. A major part of the project also includes the construction of two new digesters on the site with a new CHP biogas to energy plant. The project will generate 1 MWe from biogas when operational.
The use of Monsal technology on this site is the second large scale installation within Wessex Water. The major AD supercentre at Avonmouth also uses the Monsal technology, where over 100 tonnes per day or 40,000 dry tonnes per annum are processed to produce 4 MWe continuous electrical power output. The Avonmouth AD supercentre is one of the most efficient digestion energy projects in the UK.
Today the Avonmouth site is self sufficient in power management as a result of the high biogas to energy yield of the Monsal system. The high level of performance over a number of years coupled with the high level of reliability led to the selection of the Monsal technology for the new digestion project at Trowbridge.
Construction has started at Trowbridge and will be complete by December 2013.
Monsal advanced digestion technology has been installed on 12 major sewage sludge AD sites and four major food waste AD sites in the UK. In addition Monsal have supplied technology to over 200 conventional digesters in the UK and overseas. Monsal supply proprietary equipment and technology to both these market sectors to allow for:
- Pre-treatment technology
- High rate digestion
- Biogas to power infrastructure
- Digestate management
Today Monsal is the advanced digestion technology supplier of choice for major AD infrastructure projects in the water and waste markets.
