MBR Flat Sheet Membrane in Hospital Sewage Treatment

In our daily lives, hospitals are one of the places we visit most frequently. However, as a public health institution, hospitals generate a large amount of sewage every day. If this sewage is not effectively treated, it can have a serious impact on the environment and public health.

Problems with Traditional Hospital Sewage Treatment Methods

• Aging equipment: Biochemical systems fail, aeration disks age, pumps and blowers wear out, making it difficult to achieve the desired treatment effect.

• Irregular operation management: Insufficient staffing, low professionalism, equipment not maintained on time, and unprofessional maintenance shorten equipment lifespan and fail to timely adjust operating parameters.

• Unreasonable process design: It is difficult to meet the ever-updating discharge standards and to consistently meet the benchmarks.

• Low level of automation: Slow manual response and online monitoring equipment maintenance require a high level of professional ability.

• Insufficient space for renovating and expanding old hospital areas: Integrated equipment or more scientific spatial layouts are needed for hospital sewage treatment.

• Sludge and waste gas lack effective treatment: Hospital sewage treatment can easily result in environmental penalties or complaints from residents.

MBR Flat Sheet Membrane Treatment Technology in Hospital Sewage Treatment

MBR technology uses membrane separation equipment to retain large organic molecules and activated sludge in the biochemical reaction tank, eliminating the need for a secondary sedimentation tank, thus increasing the concentration of activated sludge and controlling sludge retention time and hydraulic retention time. This technology effectively removes organic matter, ammonia nitrogen, suspended solids, and large molecule refractory organic matter from sewage, while efficiently intercepting pathogenic microorganisms through the membrane. So, how does MBR flat sheet membrane treatment technology purify hospital sewage?

First, hospital sewage is introduced into the MBR flat sheet membrane system. The membrane surface is flushed with high-pressure water flow, expanding the membrane pores and forming a filter cake. Then, backwash water is used to wash away contaminants from the membrane surface, achieving the filtration and purification of sewage.

During the hospital sewage treatment process, the MBR flat sheet membrane system continuously undergoes dynamic adjustments to adapt to different sewage characteristics and treatment requirements. Through this method, the MBR flat sheet membrane can efficiently remove organic matter, microorganisms, heavy metals, and other harmful substances from the sewage, while retaining a certain amount of beneficial substances, such as nutrients like nitrogen and phosphorus. This not only ensures the standard of effluent quality but also promotes the healthy development of the ecosystem.

Advantages of MBR Technology in Hospital Sewage Treatment

• Reduce disinfectant usage: The MBR process can reduce the amount of disinfectant used, lowering the costs associated with disinfection processes and reducing the environmental impact of hospital sewage treatment.

• Lower disinfection by-products: The MBR process can reduce the generation of disinfection by-products, decreasing potential harm to human health and the ecological environment.

• Improve disinfection efficiency: The MBR process can effectively intercept pathogenic microorganisms, improving disinfection efficiency and ensuring the safety of the effluent quality.

It is evident that MBR technology has significant advantages in hospital sewage treatment, effectively removing pollutants from sewage and providing stable and high-quality effluent. Its high efficiency, energy-saving, and environmentally friendly characteristics make it the ideal choice for hospital sewage treatment.
