Infection Control | Is Your Clinic Compliant with Wastewater Discharge Standards?

During dental diagnosis and treatment, a large amount of contaminated wastewater containing bacteria, viruses, parasite eggs and various pathogenic microorganisms will be generated. If discharged directly without disinfection, it will not only pollute the surrounding environment, but also trigger virus transmission and excessive microbial contamination. This may lead to serious risks such as environmental pollution, acute infections and latent infections, posing a direct threat to public health.
In accordance with GB 18466-2005 Discharge Standard of Water Pollutants for Medical Institutions, all wastewater produced by dental clinics must be fully disinfected and tested to meet compliance standards before being discharged into municipal sewage pipelines.

Common Disinfection Methods
Bleaching Powder Disinfection

Principle: Chlorine dissolves in water to generate hypochlorous acid. Unstable in nature, hypochlorous acid releases oxygen atoms to achieve disinfection and sterilization.
Advantages: Excellent bactericidal effect, widely adopted by most clinics at present.
Disadvantages: Manual dosing is required with difficult dosage control, which may lead to excessive chlorine content, thus endangering human health.
2、Ozone Disinfection

Principle: An ozone generator produces ozone by electrolyzing oxygen in the air. With strong oxidizing property, ozone can rapidly destroy the cell membranes, cytoplasm, enzyme systems and nucleic acids of bacteria and microorganisms, inactivate harmful microbes, and realize efficient disinfection and sterilization.
Advantages: Faster and more thorough sterilization, stable and reliable performance, eco-friendly and pollution-free.
Disadvantages: Excessively high concentration may cause potential harm to human bodies.
Sewage Treatment System

Ozone Disinfection and Sterilization

High Efficiency: Ozone disinfection and sterilization uses oxygen in the air as raw material, with no auxiliary materials or additives required.
It delivers rapid and thorough sterilization, and also provides powerful mildew removal, deodorization and odor elimination functions.
Clean Performance: During disinfection, residual ozone decomposes back into oxygen molecules within 30 minutes, leaving no harmful residues.
It completely avoids secondary pollution caused by chemical disinfectants, with no need for post-disinfection cleaning.
Cost-effectiveness: No chemical agents are required for treatment, resulting in low operating costs and no additional follow-up investment.
Stability: 采用 aeration disc technology to disperse ozone, ensuring full contact between ozone and sewage for stable and reliable treatment results.

Intelligent Control
The intelligent control panel generates ozone according to the remaining water level in the water tank. It strictly regulates ozone discharge in line with national standard parameters to realize fully automatic operation. Featuring simple operation, the system requires no dedicated on-site supervision.

Durability
