1,Application Effect and Scope of Air Filtration Systems
Experimental data show that, after being treated by an air filtration system, the egg-laying period for poultry begins approximately 2 weeks earlier, egg production increases by 1.6%, mortality is reduced by 2%, and the feed conversion rate improves. The cost of drug disinfection is greatly reduced, and the chickens' physical condition is enhanced, extending their production cycle by 7 to 8 weeks.
Special materials and advanced manufacturing technologies are used in air filtration systems, along with supporting scientific testing facilities. These systems are suitable for large and medium-sized chicken farms to eliminate or reduce the impact of infectious diseases.
2,The Influence of Air Quality on Poultry Production
Adhering to the principle that prevention is better than cure, it is vital to prioritize environmental control over remedial measures. In artificial environments with equipment for raising chickens, the source of poultry epidemics can be completely cut off. This ensures a comfortable environment and a disease prevention system that minimizes the occurrence of infectious diseases. Migratory birds are known to carry and transmit viruses, with feces being the primary transmission channel. Viruses are excreted in particles between 0.3 µm and 1 µm, which are carried by the wind. These particles can drift into chicken coops through air inlets or gaps. Air filtration effectively blocks the airborne transmission of pathogenic microorganisms, reducing the invasion of pathogens into poultry houses.
3,Installation and Use of Air Filtration Systems
Install the air filtration device at the air inlet of the chicken coop. Generally, three layers of filtration are used:
- First layer: A low-resistance, high-capacity air filtration material that filters PM2.5–PM10 particles with an efficiency of ≥ 90%.
- Second layer: Protects the first layer by intercepting any remaining PM2.5–PM10 particles.
- Third layer: Incorporates advanced, high-efficiency antibacterial and antiviral air filtration material. The fiber surface is coated with an antibacterial substance that kills 650 species of bacteria and mold within 30 minutes. This layer effectively intercepts or kills particles carrying viruses, significantly reducing the virus content in the air within the poultry house.
After installing the air filtration system, the number of particles before and after the filter is measured using a particle laser counter. The average measured filtration efficiency for 0.3 µm particles is 98%, with a virus interception rate of 95%. The filtration and killing rate of bacterial viruses meets LoG6/MERV16 standards, capable of intercepting viruses and salmonella carried by aerosols. It also meets the ventilation requirement of a 0.08" water column at 20 Pa.
4,High-Pressure Electrostatic Cleaning and Filtration
The advantage of high-pressure electrostatic filtration is that there is no need to change filters. However, this method has several disadvantages. First, high-pressure static electricity produces ozone, which studies have shown can be carcinogenic to both humans and animals over time and may irritate the respiratory tract. Second, this filtration method is relatively low in efficiency, only absorbing particles with diameters of 0.5 microns, whereas membrane filtration can absorb particles as small as 0.3 µm. Therefore, membrane filtration is the main method used on farms.
A biofilter can also be installed at the outlet of the chicken coop. By absorbing harmful gases into biofilms, microbes in the biofilm break these gases down into carbon dioxide, water, and salts, using them as energy and nutrients for growth and reproduction. Well-designed and well-managed biofilters can reduce odors and gases like sulfur dioxide (H2S) and ammonia by up to 80%. This method has been certified as an effective way to remove odors and other gases from mechanically ventilated poultry houses and storage tanks.
