Polished CO2 provides guaranteed sparkling water quality

Polished CO2 provides guaranteed sparkling water quality

Tuesday 9th July 2013

Shepley Spring is the leading independent own label and contract water bottler, producing both still and sparkling bottled water from their 2 plants at Shepley and Kirkburton, both near Huddersfield. Gaseous carbon dioxide (CO2) creates the sparkling water, and to ensure absolute quality the company has recently installed two Carbon Dioxide Polishing Systems supplied by Thorite.

A team of Thorite's specialist engineers visited Shepley Spring and monitored the bottling line to assess the most efficient and cost-effective means of maintaining absolute purity and continuous quality for the sparkling water.

The engineers reached the decision that the only variable in the bottling process centred on the gaseous CO2 itself, and recommended the installation of two PCO2 Carbon Dioxide Polishing Systems manufactured by Parker Domnick Hunter. Using six stage multi-layer gas polishing technology, these units remove a wide range of potential carbon dioxide impurities, ensuring that gas quality is always within industry and company standards.

Jason Barlow, Shepley Spring's Technical Director, is delighted with the performance of the PCO2 polishers and said: "CO2 is central to our sparkling water output, but it is a surprisingly scarce gas. Although we rely on major suppliers it is not unknown for gas quality to fluctuate, which could potentially cause subtle changes in the bottled water's taste. However, now our CO2 is 'polished' all possible impurities and contaminants are automatically removed. Thorite's engineers have proved to be of huge assistance, understanding our stringent quality requirements and installing the PCO2s with minimal disruption to our production process."

Shepley Spring supplies to some of the country's leading supermarket chains including Morrisons, Sainsburys, Aldi, Lidl and Iceland, so the company's concern with guaranteed quality is both understandable and absolutely necessary. Nothing can be allowed to take the shine off Shepley Spring's reputation - so carbon dioxide polishing makes perfect sense!
