Division 4.3 Techniques for reducing dust emissions
United Kingdom
| Technique | Description |
|---|---|
| Water fogging | Water is sprayed by nozzles at high pressure to produce fine droplets that absorb heat and fall by gravity to the floor, moistening dust particles that become heavy enough to drop as well. Wet or moist litter needs to be avoided. |
| Ionisation | An electrostatic field is created in the house to produce negative ions. Circulating airborne dust particles are charged by free negative ions; particles are collected on the floor and room surfaces by gravitational force and electrostatic field attraction. |
| Oil spraying | Pure vegetable oil is sprayed by nozzles inside the house. A mixture of water and around 3 % vegetable oil can be also used for spraying. Circulating dust particles are bound to the oil drops and collected in the litter. A thin layer of vegetable oil is also applied on the litter to prevent dust emissions. Wet or moist litter needs to be avoided. |
