To guarantee the safe discharge of medical wastewater, we must fully implement Medical Wastewater Monitoring and oversee its collection, transportation and other related processes. Chlorine disinfectants are widely used to sterilize medical wastewater during treatment, which necessitates the monitoring of total residual chlorine in medical wastewater. This article provides a brief overview of the monitoring system for total residual chlorine in medical wastewater.

Prevent Excessive Disinfection to Safeguard Drinking Water Safety

During the pandemic, disinfection and medical wastewater treatment required heightened attention rather than relaxation, with more intensive disinfection measures adopted compared to normal periods. Monitoring for coliform bacteria and total residual chlorine are mandatory testing items stipulated by relevant authorities.

It is also critical to first understand the characteristics of medical wastewater before conducting its treatment and monitoring. Medical wastewater contains a large quantity of pathogenic bacteria, which must undergo disinfection prior to discharge. Chlorine-based disinfectants are among the most commonly used sterilization agents. Generally speaking, the concentration of disinfectant residue is positively correlated with bacterial levels in water: a higher disinfectant residue concentration indicates fewer bacteria. However, such residue must comply with specified regulatory limits to meet safety requirements.

Particular attention must be paid to excessive total residual chlorine, as exceeding the standard will pose direct health risks to people consuming drinking water. Total Residual Chlorine Online Analyzers can be deployed to test treated wastewater, accurately measure total residual chlorine levels, and maintain them within safe thresholds. This avoids water pollution caused by over-disinfection and ensures water quality safety.
