Fugitive dust emissions occur at multiple points through the manufacturing processes in non-ferror metal plants. Main sources of emission include raw material storage and handling, roasting, smelting, refining, melting and casting. Main air pollutants emitted include CO2, CO, NOx, PM10, sulfur oxides (SOx), VOCs (volatile organic compounds), dioxins & furans, NH3, hydrochloric acid (HCl), fluorine & inorganic compounds, chlorine & inorganic compounds, PAHs and PFCs. The dust ladden gas flow generated during the manufacturing processes has the following characteristics:

● High moisture level at high temperature

● Acid corrosive

● Fluctuated airflow velocity

● High dust density

Aokai’s depth of expertise and understanding of the unique filtration challenges that exist in the non-ferrous metals industry has seen many innovative filtration solutions developed specifically to help solve these challenges. Our primary goal is to help industrial customers keep operating and maintenance costs to a minimum with safe, clean, and efficient production using complete solutions for dust and fume filtration at all stages in the non-ferrous metal manufacturing process. Our filtration solutions have the following advantages:

● Increased airflow
● Reduced dust emissions
● Increased filter bag life due to reduced cleaning
● Increased energy efficiency due to reduced cleaning
● Potential decreased number of installed filter bags
