Protoc TOC analysers at Heineken continue to optimise effluent quality and reduce operational costs
The Heineken - John Smith’s Brewery located in Tadcaster, currently use six Protoc TOC analysers to monitor key effluent streams and proactively manage their site effluent. The Brewery has used the Protoc TOC analysers technology for more than 16 years, from making the initial installations back in 2004. Some of the older instruments have now recently been replaced with the latest Protoc technology since these instruments are an integral part of the Company’s environmental compliance program. The site has used these instruments to gain a better understanding of each production area and reduce the load entering the on-site treatment facility. Improved measurement and control, has improved effluent quality and reduced operational costs.
In September 2004, John Smith’s Brewery located in Tadcaster, decided to investigate how they could monitor their effluent quality and identify product loss. They approached Pollution & Process Monitoring Ltd (PPM) to discuss their requirements and design a suitable monitoring solution.
To simplify the delivery of the project, the Project Manager at John Smith’s, wanted a complete turnkey package from a single supplier.
Analyser reliability was also a critical consideration. The project manager contacted a number of producers in the Food and Beverage sector which already had the Protoc analyser technology installed, to establish that the instrumentation was suitable for the brewing industry.
PPM onducted a comprehensive site survey, to evaluate the possible monitoring locations across the site and identified seven key locations:-
• Beer Destruction
With such extensive monitoring in place, it was concluded John Smiths would be able to pinpoint any issues from specific production areas and ultimately improve effluent quality. The original installation of the Protoc analyser technology including pre-fabrication, was finally completed in March 2005.
Future expansion of the Brewery was also being planned however the local Yorkshire Water treatment plant was not capable of handling any further load from the proposed expansion. Consequently, John Smith's decided to build an on-site effluent treatment plant, after which the Protoc analyser technology then played a key role in controlling the load entering the treatment facility and ultimately ensuring compliance to the imposed discharge consent.
A further Protoc analyser was subsequently located in the Brewery yard, to monitor the surface water discharge to a local water course, to ensure rainwater collected in this area was free of contamination.
The Brewery is now part of the Heineken Group and more recently, the Company has upgraded some of the original installations after 15 years of continuous operation. The most recent investments have included relocation of one system into a fully engineered outdoor kiosk, providing improved access and weather protection. An additional monitoring station was also added to a brand new fermentation line which was commissioned in 2020.
Currently, the Protoc technology operate 24-7 in six locations. The continued use of the Protoc analyser technology over the sixteen year period, is testament to the proven reliability of measurement and the service support which PPM provides to the end user.
