These devices are essential for the reduction of particulate emissions in industries. Contributing to the protection of the environment. First, we examined in detail the generalities of a “PES”. Then, we proceeded to a thorough description of these essential devices. Finally, we carried out experimental experiments, followed by a discussion and an in-depth analysis of the results obtained.frThesis
