Hospitals are major water consumers. Water is widely used in daily operations: hospitals attach great importance to environmental sanitation and need to protect staff and patients from bacteria and viruses, so large amounts of water are used to clean every corner of the hospital. In addition, water is also required for preparing various medicines and disinfectants. After being used in the hospital, most of the water is discharged in the form of medical wastewater, which contains improperly formulated reagents, excessive potions, and expired pharmaceuticals.

These pharmaceuticals and disinfectants can pose hazards to the surrounding environment. Worse still, medical wastewater may carry pathogens from patients’ body fluids. If discharged directly into natural water bodies without treatment, it will very likely cause ecological damage and the spread of diseases, bringing a host of potential risks in total.

So what is the solution? Professional water quality monitors are the ideal way to cut down such hazards.

Before discharge, hospital medical wastewater must undergo strict monitoring. An online Medical Wastewater Monitoring system is adopted to detect water composition. The monitored data is used to assess water safety. Any substandard wastewater must be disinfected and sterilized until the water quality meets discharge standards. Only then can it be discharged into the sewer network and delivered to sewage treatment plants for further purification.

Among all monitoring indicators for medical wastewater, coliform bacteria is one of the most essential and mandatory parameters. It is mainly used to detect bacterial content and evaluate the sanitary safety of wastewater.

The WECT-900 Online Coliform Analyzer manufactured by Hangzhou Modi is specially designed for this monitoring task. Adopting the principle of enzyme and bacterial culture, the device measures the proportional change of optical signals generated after the reaction, so as to accurately reflect the total bacterial count in water samples.
