Turn-key system cut footprint in half

The island of Malta has no natural water supply. All drinking water is extracted from deep groundwater sources. Aquani water supplies high quality, locally produced bottled water to the inhabitants. Located at the heart of the Maltese buzz, the company is known for their fast and efficient delivery services and only top quality water with a balanced mineral content. With larger 11 and 19 L bottles for local businesses, Aquani has now expanded their offering by adding 2 liter bottles to the consumer market.

The problem.

Aquani has been previously using ozone for many years to sanitize the final product and to ensure the shelf-life and taste. However, the capacity of the old ozone system was out of range following the increased capacity requirements with the new 2 L bottling line. The old ozone system could not reach the targeted dissolved ozone levels. In addition, the available space was a concern since the new bottling line more than tripled the water flow.

The solution.

Aquani turned to Mellifiq to help them upgrade the total ozone capacity. With complete turn-key solution, an Ozonetech RENA Vivo B1 ozone system was delivered and installed in-line following the RO and filter stations. In order to maintain proper dissolved ozone levels, ORP control was integrated into the control system including sensor. Ozonetech was also able to accommodate for hydraulic pressure variations in order to operate each bottling line individually or in combination. The advanced operational mode control was a perfect fit.

The upgrade resulted in half the footprint compared to the previous ozone unit, but with more than three times the capacity. The system capacity can easily be upgraded without any added floor space. The ORP control was tuned specifically to maintain stable ozone levels regardless current water flow. The system operates at very low noise levels compared to the old unit. Due to the warm conditions, a dedicated cooling system was included in the delivery to avoid using local tap water.

In the end, this results in a more reliable bottling production with a more efficient system that occupies less space and lowers operational costs with opportunities to upgrade production capacity.
