By the exhaust fan at the exit of the unit,smoke and dirty air come to the rough filtering unit, then pass through cooling unit, then enter to multiple passed ESP filter. In this area particles that are smaller than micron got electrified and captured.
At the end of the process clean air flows
through the atmosphere. Particles that are bigger then drops, fall from filter by gravity and collected in ESP channels. It can be used as fuel mix afterwards or can be collected by licensed companies.
