Bright Blue

Coca Cola Specification

This is the most advanced ozone system for prepared water disinfection currently on the market.
The Bright Blue CCS systems were designed and developed specifically for the bottling of “Bon Aqua” brand water. It conforms to Coca Cola standards for Ozonation and electrical equipment.

These systems are designed to meet Coca Cola specifications for the disinfection of prepared water, namely 4 minutes of ozone contact time at a level high enough to ensure ozone residual after bottling of around 0.5ppm. This is order to achieve a 5 Log reduction in microbiology.

There are two main components consisting of a large contacting vessel for Product (Syrup) ozonation and a control panel.

The large contacting vessel is sized to allow for an ozone/product contact time of 4 minutes at peak bottling flow. The ozone level in this tank is electronically controlled so as to give an ozone residual in the bottle after filling as required by the bottler. This is typically between 0.3 and 0.6 ppm.

A centralised ozone generator & control panel governs the operation of the system. The unique user interface features large easy to read dials and icons. Operation is easy and intuitive with varying access levels:

• One touch On/Off for the operator
• Access to ozone set-point & diagnostics for the line manager
• Full access to all levels for the administrator

Continuous Ozone measurement is done using a Dr. Reiss GMBH ozone probe and measuring cell. This is coupled to a dedicated P.i.D controller which enables “Auto-tuning” of the ozone dosage.
This allows for accurate control of the desired dissolved ozone level to within as little as 1% of the set-point. An optional Ethernet connection allows the entire system to be monitored & controlled from a Computer workstation.

Easy to Use, Easy to Maintain

The Bright Blue system has been constantly improved and refined since the first unit was produced in 2001.
Our focus has always been on quality and reliability, so much so that many of our customers regard our systems as amongst the most reliable in their plant.

The systems are extremely easy to operate. On a day to day basis the operator simply pushes the start/ stop button.
The PLC does the rest. Only occasional interventions are required to calibrate the system against an ozone test kit. Maintenance is very straightforward with all major components being modular and easy to access.

Wassertec hold a full spares inventory at all times.

Wassertec Oxygen Generator

The built-in oxygen generator converts compressed air to oxygen at up to 95% purity. Unlike some other models, it is fully serviceable and can be easily & inexpensively re-sieved in the event of water ingress.

Wassertec Ozone Modules

Designed to produce high concentrations of ozone without the need for water cooling the ozone modules each have a max. output of 10gr/hr. Ozone output is regulated from 0-100% via a 4-20mA input signal from the PLC. Ozone cells have a 10,000 service interval.

Power and Control

Power & Control The upper rail contains all the circuit breakers and switchgear for the system. The lower rail holds the PLC and PID controllers. Components are all Coca Cola approved.

Component details

De-Gassing & Ozone Sampling

The top of the contacting systems feature a special ozone resistant de.gas valve. This allows undissolved ozone to be vented safely away from the production area whilst maintaining tank pressure.

The ozone sampling probe and flow cell are fitted to the side of the contactor. Sample flow is controlled by a needle valve and rotameter built into the flow cell. This ensures accurate sampling and maximises the duty life of the replaceable probe membrane.

Ozone Leak Detectors

Ozone & Oxygen sensors are mounted in the bottling hall and in the ozone plant room. They are interlocked to the PLC. In the event of ambient ozone levels exceeding the OHS limit the ozone system will be shut down and a warning displayed.

Sterile Sampling Tap

The contacting systems are fitted with Guth Q-Fit sampling taps as per Coca Cola requirements. These can be flushed with a disinfecting solution after samples have been taken.
