Abstract Scope |
The fine particles in media such as air and water have been recently caused in the view of environmental pollution. The fine dust in the air and the fine plastics in water have been challenged to solve with conventional techniques such as filtering, electrostatic, etc. We investigated the novel technology for agglomerating the ultra-fine particles in air induced by sound wave with the frequency ranging from 20Hz to 20kHz and the sound pressure level (SPL) from 0 to 100dB. When the low frequency and the SPL under 50Hz and 100dB were applied in the constraint box containing ultra-fine particles, the rate of agglomeration of ultra-fine particles was nearly 5 times higher than that without operating. It is concluded that the agglomeration behavior of ultra-fine particles was effectively induced by a sound wave, and also is expected to be applied to the inter-structure and intra-structure having the polluted air. |
