Particulate and VOC Capture system concept(s):

## Components:

1. Fan assembly (motor, blades, housing)
2. Carbon black coating
3. Binder material for coating adhesion
4. Removable blade design (for easy replacement/recoating)

## Coating Process:

1. Prepare a slurry of carbon black with a heat-resistant, flexible binder
2. Apply the coating to fan blades using a spray or dip method
3. Cure the coating according to binder specifications
4. Balance the fan blades after coating

## Operational Considerations:

1. Monitor fan performance for any changes in efficiency
2. Implement a regular inspection schedule for coating integrity
3. Develop a replacement/regeneration schedule based on estimated saturation times
4. Consider a multi-fan system to allow for continuous operation during maintenance

## Safety Measures:

1. Ensure proper ventilation of the fan area
2. Implement fire safety measures due to potential VOC concentration
3. Use appropriate PPE when handling coated blades or during maintenance

## Potential Enhancements:

1. Grooved or textured blade surface to increase effective surface area
2. Electrostatic charging of the carbon black coating to enhance capture efficiency
3. Integrated sensors to monitor VOC levels and coating saturation

## Disposal/Recycling:

1. Develop a safe method for removing saturated coating
2. Explore potential for regenerating the saturated carbon black
3. Ensure proper disposal of VOC-laden materials
