Precise Ozone Control, Safeguarding the Purity of Bottled Water

DABECO W771-DOZ1.2MA2 Ozone Analyzer

In bottled water production, "purity" is the lifeline. Every step, from water source treatment to filling and capping, requires strict control. Among these, the residual control in the ozone disinfection process is particularly critical—it must completely eliminate microorganisms in the water while preventing excessive ozone residues that could affect taste and safety. The W771 instrument from North Measurement & Control, paired with the Germany made OZ1.2MA2 ozone sensor, has become an "invisible guardian" for bottled water enterprises to protect quality with its precise monitoring and intelligent control capabilities.
Industry Pain Point: The Dilemma of Balancing Ozone Residues
The bottled water industry has strict standards for ozone usage: According to Packaged Drinking Water (GB 19298-2014), the ozone residual in finished water must be ≤ 0.05mg/L (i.e., 0.05ppm). Excess ozone can cause the water to have an irritating odor and even damage water quality stability; insufficient disinfection, on the other hand, may lead to excessive total bacterial count (standard requirement: ≤ 20CFU/mL), posing the risk of product recall.
In traditional production, ozone concentration monitoring relies on manual sampling and testing, which has two major drawbacks: First, lag—it takes more than 30 minutes from disinfection to the release of test results, during which unqualified water may have already entered the filling process. Second, insufficient accuracy—test strip methods or offline testing have large errors, making it difficult to capture subtle fluctuations at the 0.01ppm level, often resulting in the dilemma of "over-disinfection" or "insufficient disinfection."
Solution: The "Synergistic Combination" of W771-DOZ1.2MA2

Targeting the precise monitoring needs of the bottled water industry, the monitoring system composed of the W771 instrument and OZ1.2MA2 ozone sensor provides full-process protection from "detection" to "control":

Quality Optimization: "Odor complaints" caused by excessive ozone have decreased by 80%, and consumer satisfaction has increased to 98%.

Efficiency Improvement: Automatic control reduces manual intervention, the ozone consumption per ton of water is reduced by 15%, the annual cost savings on consumables exceed 120,000 yuan, and equipment maintenance time is shortened by 60%.

In today's highly competitive bottled water industry, "purity" is not only a standard but also a reputation. With precise monitoring and intelligent control, the W771-DOZ1.2MA2 helps enterprises hold the quality bottom line, making every bottle of water carry "peace of mind" and "trust" and become an invisible business card to impress consumers.
