Finlays Americas’ tea production facility at Cranston, Rhode Island, has recently installed an ozone generator to the reverse osmosis system that supplies water for products and process cleaning. Ozone generators create aqueous ozone, which kills bacteria over 3,000 times faster than chlorine, but leaves no residue or by-products in the water.
Previously, the team at Cranston needed to clean the system weekly – a four to five-hour process that used large quantities of chlorine, and massive amounts of water to rinse. During the cleaning process, the team were unable to run production, clean-in-place the production equipment, or run trials for new products, so the ozone generator is helping facilitate safe, sustainable processes, while contributing to cost efficiencies.
