W771-DCS4.0 Solves Meat Plant Cleaning Water Bacteria Issues

A large-scale meat processing enterprise found during daily quality inspections that Escherichia coli (E. coli) on the surface of tools such as knives and cutting boards exceeded the standard (average detection value reached 45 CFU/cm²). Investigation revealed that manual control of disinfectant dosage was unstable, resulting in residual chlorine concentration in cleaning water fluctuating between 0.05-0.8 ppm, which failed to consistently meet the process requirement of 0.2-0.4 ppm.

Solution
The W771-DCS4MA2 residual chlorine monitoring system was installed on the tool cleaning line, with specific implementations as follows:
1. Monitoring Point Setup
2. Intelligent Linkage Control

Operational Efficiency Improvement
Labor Cost: Eliminated manual testing every 2 hours, saving 3.5 working hours per day
Chemical Consumption: Precise control reduced monthly sodium hypochlorite usage from 850L to 580L (↓31.7%)
Equipment Maintenance: Dosing pump startup/shutdown frequency decreased from 45 times/day to 12 times/day, reducing mechanical failure rate by40%

Compliance Management
The system automatically records residual chlorine data and transmits it to the central control room via RS485, generating daily reports that comply with GB5749-2006 (National Standard for Drinking Water Quality). During the latest unannounced inspection by regulatory authorities, water quality records achieved 100% compliance for 12 consecutive months.

Customer Feedback
"This system has completely transformed our water quality management method!In the past, residual chlorine in tool cleaning was tested manually, leading to large data fluctuations and high risks of microbial overreach. Now, the LCD screen of the W771 instrument displays real-time concentrations, and three sets of relays automatically control the dosing pump—when residual chlorine is below 0.2 ppm, the alarm light flashes and the dosing pump starts immediately; when it exceeds 0.4 ppm, the pump shuts down automatically.
