High filtration accuracy: The high-efficiency filter has excellent filtration accuracy and can remove more than 95% of suspended solids in the water. It also has a certain removal effect on macromolecular organic matter, viruses, bacteria, colloids, iron and other impurities. After good coagulation treatment, the turbidity of the treated water can be reduced from 10NTU of the inlet water to less than 1NTU, ensuring the cleanliness and purity of the outlet water quality.
Fast filtration speed: The filtration speed of a general high-efficiency filter can reach 40m per hour, and the highest can even reach 60m per hour, which is more than 3 times that of an ordinary sand filter, effectively improving the efficiency of water treatment.
Large pollutant holding capacity: The high-efficiency filter has a large pollutant holding capacity, generally 15-35kg/m³, which is more than 4 times that of an ordinary sand filter. It can effectively adsorb and capture impurities in the water and extend the filtration cycle.
Low backwash water consumption rate: The backwash water consumption of the high-efficiency filter is relatively small, usually less than 1-2% of the cycle filtration water volume, saving water resources while ensuring the normal operation and filtration effect of the equipment.
Low dosage and low operating cost: Due to the filter bed structure and filter material characteristics of the high-efficiency filter, the flocculant dosage is usually 1/2 to 1/3 of that of conventional technology, which reduces the cost of dosing. With the increase of cycle water output, the operating cost per ton of water is also reduced accordingly, saving operating costs.
Small footprint: Under the same water output, the footprint of the high-efficiency filter is only less than 1/3 of that of the ordinary sand filter, saving space resources and suitable for layout in limited sites.
Strong adjustability: The high-efficiency filter has good adjustability, and parameters such as filtration accuracy, interception capacity, and filtration resistance can be adjusted as needed to meet different water quality and treatment requirements.
Durable filter material: The high-efficiency filter uses durable filter material with a lifespan of more than 20 years, reducing replacement and maintenance costs and improving the reliability and stability of the equipment.
The service life of the high-efficiency filter is an important factor affecting the air purification effect and system performance, which is mainly caused by the following three reasons:
The filter material area of the filter is too small or the unit dust holding capacity is too small:
The filter efficiency and life of the filter are closely related to the area of its filter material and the unit dust holding capacity. If the filter area is too small or the unit dust holding capacity is insufficient, the filter will reach saturation in a short time, affecting its normal operation and service life.
The filter efficiency of the pre-filter is low:
The low filter efficiency of the pre-filter will cause the high-efficiency filter to bear too much particulate load, accelerate the pollution and clogging of the filter, and shorten the service life of the high-efficiency filter.
The user has too high expectations for the service life of the filter:
Sometimes the user has too high expectations for the service life of the filter, and may ignore the actual working environment and use conditions of the filter, causing the filter to fail prematurely.
The national standard GB13554-92 stipulates that the high-efficiency filter is:
Filter whose efficiency is ≥99.9% according to the sodium flame method test specified in GB6165;
Sodium flame method test, the efficiency of ≥ 99.99% of the filter
Sodium flame method test, the efficiency of ≥ 99.999% of the filter
Filters with efficiency ≥99.999% for particles ≥0.1 m in size.
The former refers to general high-efficiency filters. In comparison, the efficiency of high-efficiency filters is generally defined as ≥99.97% abroad. The latter refers to ultra-high-efficiency filters.
Selection of a sufficiently efficient filter (pre-filtration).
Choose a filter with a large filter area
HEPA filters must be tested one by one
Under the same air volume, choose the filter with low initial resistance.
Select filters of common size
HEPA filters should not be washed. Here’s an analysis of why washing HEPA filters is not recommended:
Structural Integrity
Deformation: Washing can cause the filter to lose its shape, leading to gaps where unfiltered air can bypass the filter.
Effectiveness
Washing may not remove all trapped particles, and the remaining debris can obstruct airflow and reduce filtration efficiency.
Drying Issues
Moisture Retention: After washing, HEPA filters can retain moisture, which can lead to mold and bacteria growth within the filter.
Manufacturer Guidelines
Instructions: Most manufacturers explicitly state that HEPA filters should not be washed.
HEPA filters are highly effective at capturing a wide range of airborne particles, but there are certain types of contaminants that they do not effectively remove. Here are some key categories of particles and substances that HEPA filters cannot eliminate:
1. Gases and Vapors
Volatile Organic Compounds (VOCs): These include a variety of chemicals found in paints, cleaners, and other household products.
2. Smoke
Fine Smoke Particles: While HEPA filters can capture larger particulate matter from smoke, they may not be as effective against very fine particles present in smoke, especially from sources like wildfires or tobacco.
3. Bacteria and Viruses
While HEPA filters can trap a significant percentage of bacteria and viruses due to their small size (typically 0.3 microns and larger), they do not eliminate them entirely.
4. Large Particles
Dust and Pollen: HEPA filters are designed to capture particles as small as 0.3 microns, so larger particles like dust and pollen can also be filtered out.
1. Classification Standards
HEPA filters are often classified according to standards set by various organizations. The most recognized standards include:
H10 to H12: These filters have efficiencies ranging from 85% to 99.5% for particles of 0.1 to 0.3 microns.
H13 and H14: These are higher-efficiency filters, capturing 99.95% and 99.995%, respectively, of particles down to 0.1 microns.
2. Efficiency Classes
HEPA: Standard HEPA filters that meet the DOE requirement (99.97% at 0.3 microns).
ULPA (Ultra Low Penetration Air): Filters that capture 99.999% of particles down to 0.12 microns.
1. HEPA H13 filters remove 99.95% of particles ≥0.3 microns.
2. It is widely used in cleanrooms, hospitals, and laboratories to maintain air quality.
