Carlsberg Britvic produces 14 million cases of carbonated and still beverages a year. They were looking for new ways to reduce water use on its production sites in the UK. At the company’s bottling plant in the Beckton suburb of East London, the company saw a potential of reducing water in its bottle rinsing – a high water-use area. 

The Grundfos Bottle Rinse Reuse System is a modular filtration system uniquely combining micro and carbon filtration, UV AOP, Grundfos Digital Instrumentation Dosing (DID) control, CRE and dosing pumps, patent-filed valving, SCADA system, custom built tanks and turnkey installation. The combination of the technologies used and how it is controlled is unique and is pending a patent.  

The Grundfos Bottle Rinse Reuse System stands up against the wall by one of the bottling lines. It captures the rinse carousel’s water and pumps it through a Grundfos patent-pending water treatment process before sending it back to the bottle-rinse units.   

The solution is risk-free, automatically diverting poor quality batches to the drain. It did not require any shutdown of production.

Grundfos’ custom-designed water treatment system for Carlsberg Britvic has saved about 64,272,000 litres per year, with a return on investment of 2 years. The CO2 impact is minimal, using 0.5 kWh per 1000 litres of water. It saves the company about 60 million litres of water a year – the amount that 500 UK households use in a year. The method is significantly more economical and environmentally friendly than traditional wastewater treatment, requiring considerably less energy, chemicals, water and labour.
