The selection of air filters should be based on the performance requirements of the application, including primary, medium, and high-efficiency filters. The four key indicators for evaluating air filters are air filtration speed, filtration efficiency, filter resistance, and dust holding capacity. Choosing the appropriate filter requires considering these indicators to meet the needs of different scenarios. Proper configuration of filters can enhance filtration efficiency, extend equipment lifespan, and reduce operating costs.

MERV (Minimum Efficiency Reporting Value) is a standard used to evaluate the efficiency of air filters, measuring their ability to capture particles in the air. The MERV scale ranges from 1 to 16, with higher numbers indicating higher efficiency. MERV 1-4 is suitable for residential and low-demand commercial environments, primarily capturing large particles like dust; MERV 5-8 is used in ordinary homes and offices, removing medium-sized particles like pollen; MERV 9-12 is appropriate for hospitals, laboratories, and other high-demand environments, capturing bacteria, mold, etc.; MERV 13-16 is for clean rooms and high-standard laboratories, removing almost all small particles, including viruses. When selecting the appropriate MERV rating, it's important to balance filtration efficiency and airflow to avoid overburdening the system.

Nuclear wastewater refers to the wastewater generated by nuclear power plants in normal daily activities, mainly including cooling system wastewater, nuclear fuel reprocessing wastewater, auxiliary facility wastewater, etc. Radioactive substances mainly include tritium, uranium, plutonium, thorium, and radium. Since these radioactive wastewater will directly or indirectly affect human health and life, they need to be treated before they can be discharged.
