Water Quality for Coca-Cola with Blue I's Analyzers

Coca-Cola Case Study

Uncompromising Water Quality for Soft Drinks

Manufacturer’s Quality Goals

2 Blue I Water Technologies Ltd.

Soft drinks contain 95%-99% water

Product must meet health and regulatory requirements

Must maintain consumer trust and market share

Main ingredient in soft drinks?

WATERWATER

Water Treatment Challenges


Taste and quality of the final product can be affected by:

Quality of water sourcesTraces of metals and other unwanted elementsDisinfection processesTreatment residuals

Government regulations and industry standards evolve and become more stringent

Must find ways to meet water standards without modifying taste and quality

Water Quality Goals – Coca-Cola


Providing unchanging and recognized taste for Coca-Cola’s renowned beverages

Water standardization for consistency in taste nationwide

Coca-Cola’s 5-Step Approach to Water Quality


Enhanced filtration (pathogenic microorganisms)

Alkalinity reduction, if needed (taste)

Disinfection (secondary barrier against microorganisms)

Carbon purification (chlorine, organics for safety and taste)

Polishing filtration (carbon fines)

Monitoring Water Treatment Processes


Water must be constantly monitored to verify chlorine has been fully removed

Very low chlorine levels require high accuracy, high resolution and fast response time in monitoring the water

Most critical for monitoring are the final stages of production, prior to bottling

The Solution


25 Coca-Cola bottling facilities around the world have installed Blue I’s HYDROGUARD HG-702 multi-parameter colorimeter at critical points on their production lines

High accuracy, fast response analyzers to monitor water quality before bottling

HYDROGUARD HG-702 Precision


Water quality assurance before bottlingThe HG-702 ensures that the final high quality of water for Coca-Cola’s beverages on these production lines is maintained by constant monitoring of total chlorine, conductivity and pH levels.

Measuring free and/or total chlorine with high resolution (0.01 ppm) and accuracy and short measurement delay

Zero reading of total chlorine before reverse osmosis

The Technology


The Technology


HYDROGUARD HG-702Accurate Colorimetric Analyzer based on DPD (N,N-Diethyl-p-

phenylenediamine) colorimetric method

In the presence of chlorine, the DPD rapidly reacts to form a red color, the intensity of which indicates the level of chlorine concentration.

Low reagent (DPD) consumption (~0.03ml/sample), in keeping with environmental and total cost considerations\

Specially designed spectrophotometric measuring cell

for automated reagent mixing and hands-free cleaning

as fluids and/or reagents fill the measuring tube, they are effectively mixed to obtain a homogenized solution

eliminates manual cleaning

A built-in sensor detects and measures the solution as it is emitted and determines chlorine concentration with high accuracy and at precise pre-programmed intervals.

Includes multiple interfaces with external equipment using 4-20mA indication & control, alarm relays and industry standard Modbus protocol support.

Advantages at Coca-Cola Bottling Plants


MaintenanceSelf-calibration and true zero with every measurement;

no need for initial calibration

Automatic self-cleaning photocell with a built-in piston in each unit (patented system)

Low reagents consumption (~0.03mL/sample)

Manual procedures such as periodic reagent replacement are easy to perform and do not require specialized skills

Maintenance reminders and alarms provide useful information about incidents and timing so as to ensure effective response

Reduced total cost of ownership (TCO)

Advantages at Coca-Cola Bottling Plants


PerformanceHigh precision, consistent readings - tested vs. lab

equipment

Measuring free chlorine and total chlorine on the same water sample assures high accuracy

Measurement range: 0-10 ppm

Flexible measurement interval: 2 to 10 minutes

Measurement accuracy (+/- 5%)

Reagent mixing, sample de-bubbling and cell cleaning all performed by one unit

Six independent relays for equipment control

Optional programming to measure additional parameters: pH, Redox, conductivity, turbidity, temperature

Proven Results


Lab test precision for top water quality at Coca-Cola’s bottling lines

Blue I’s analyzers serve as gatekeepers to ensure quality of beverages prior to bottling

Analyzers adapted and programed to meet unique needs of each site, allowing combination of measurements in single system

Self-calibration, self-cleaning, long-term stabilization support more efficient and reliable processes

Analyzers play critical role in maintaining Coca-Cola’s high regulatory and health standards
