What is medical wastewater?

Medical wastewater is a source of wastewater arising from the activities of medical facilities such as hospitals, clinics, laboratories, research institutes… In medical wastewater contains many organic substances, pathogenic microorganisms, toxic chemicals,… If discharged directly into the environment without treatment, it will cause serious pollution, adversely affecting public health. Therefore, medical wastewater treatment is an urgent issue that needs to be focused.
Medical wastewater treatment plays an important role.
  • Environmental protection: Medical wastewater treatment helps remove contaminants, ensuring that wastewater after treatment meets the permitted standards before being discharged into the environment. Reduce water, soil and air pollution.
  • Protect public health: Toxic substances, microorganisms in medical wastewater if not treated will be dangerous when people are exposed. Wastewater treatment removes these harmful factors, minimizing the risk of infectious diseases to the community.
  • Compliance with the law: Medical wastewater treatment is a mandatory regulation for health facilities under the Law on Environmental Protection. The treatment helps health facilities operate in accordance with the law.

Medical wastewater treatment technology

There are many technologies applied to effectively treat medical wastewater, such as:
  • Bioremediation: Using the process of microbial activity to decompose organic matter in wastewater into CO2 and H2O. This technology has the advantage of low cost, suitable for many types of wastewater. However, the treatment process is slow, difficult to thoroughly treat some toxic substances.
  • Chemical treatment: Use chemicals to oxidize, reduce pollutants in wastewater. This technology is fast, efficient but higher cost than biological treatment.
  • Membrane treatment: Using reverse osmosis membrane to filter and remove impurities, bacteria. This is a simple technology, easy to operate, cost less.
  • Treatment by combined membrane technology: Combining many processing technologies such as membrane filtration, biological treatment, advanced oxidation… help thoroughly treat pollutants in medical wastewater. This is considered the optimal medical wastewater treatment technology today.
  • Treatment by combined membrane technology: Combining many processing technologies such as membrane filtration, biological treatment, advanced oxidation… help thoroughly treat pollutants in medical wastewater. This is considered the optimal medical wastewater treatment technology today.
  • Treatment by physical methods: Using physical methods such as heating, irradiation, ultrasound… to kill bacteria and pollutants. This method is highly effective but requires large investment costs.

Typical medical wastewater treatment Steps

The medical wastewater treatment process usually consists of basic steps:
  • Collection: Collect all wastewater generated from the areas in the hospital to the centralized treatment system.
  • Pretreatment: Perform initial treatment steps such as sedimentation, solid removal, pH adjustment… helps to remove large impurities.
  • Bioremediation: Uses the active process of aerobic or anaerobic bacteria to decompose organic compounds into inorganic substances.
  • Chemical treatment: Oxidation of remaining pollutants with chemicals such as chlorine, ozone…
  • Membrane treatment: Using reverse osmosis membrane, ultrafiltration membrane to remove bacteria, heavy metal ions.
  • Complete treatment: UV sterilization, end-chlorination to completely destroy pathogenic bacteria. Adjust parameters to meet standards before discharging into the environment or reusing.
In order to ensure high efficiency of medical wastewater treatment, the treatment steps need to be designed appropriately, calculate the balance of capacity and treatment time. The treatment system also needs to be operated and maintained properly.

Effective medical wastewater treatment solutions

In order to treat medical wastewater with good results, it is necessary to note some of the following solutions:
  • Selection of treatment technology suitable for wastewater flow and composition. Priority advanced treatment technology, high automation for thorough treatment.
  • Separate the medical wastewater collection and treatment system with domestic wastewater to have a separate treatment process.
  • Invest in a centralized, closed wastewater treatment system to control the treatment process well.
  • Install monitoring equipment, automatic monitoring to ensure the system works stably.
  • Develop and strictly implement the process of operation and periodic maintenance of wastewater treatment systems.
  • Strengthen the management and supervision of the collection and treatment of medical wastewater. Strictly handle waste discharge violations.
  • Training, raising awareness and responsibility of the staff operating the wastewater treatment system.
The proper treatment of medical wastewater not only helps protect the environment but also contributes to ensuring health and improving the quality of life of the community. This should be considered the responsibility of every health facility as well as an urgent issue of society. The investment in effective medical wastewater treatment technology, frequent upgrading and strict management of the treatment system is essential. At the same time, the active participation of the government as well as the awareness of each individual in protecting the environment also contributes significantly to bringing a fresh living environment to the community.
