There is no European regulation on the end of life management of manufactured nanomaterials. Such nano-containing products or nano-waste can end up in incineration plants. Nevertheless release of nanoparticles is a sanitary and environmental issue. The study aimed to quantify the filtration performance of a pulse-jet bag filter at the laboratory-scale regarding submicronic particles with a nanosized fraction during several clogging/unclogging cycles. The bag filter was operated in realistic conditions, as close as possible to those found in flue gas treatment lines of waste incineration, in terms of temperature (150°C), humidity (3% RH), filtration velocity (1.9 cm/s) and injection of sorbent reagents (activated carbon and sodium bicarbonate). The study focused on the filtration performance (filter pressure drop and particle collection efficiency) at the beginning of the lifetime of the bag filter before stabilizing the residual pressure drop resulting from the previous filtration cycles. The maximum filter pressure drop was set at 150 Pa for all filtration cycles. Once the maximum pressure drop was reached, the filter was unclogged using pulse-jet system. The experiments revealed...
