Coating & Surface Finishing
Industrial paint, UV coating, adhesive, metal finishing and multi-booth surface processes.
Processes and emission sources
Mist and particulate pretreatment protects a zeolite concentration or direct oxidation system selected around booth schedules and solvent load.
Real engineering project deployed by FluxFine Environmental.
Common pollutants
- Paint mist
- Aromatic hydrocarbons
- Esters
- Ketones
- Alcohols
Typical conditions
- Large booth airflow
- Low average with peak VOC loads
- Intermittent shifts
- Mist-bearing exhaust
Engineering priorities
- Pretreatment loading

Stack monitoring
Zeolite Rotor
Large airflow, low concentration VOCs (coating, printing, electronics)
RTO
Medium–high concentration VOCs, complex solvent mixes, heat recovery duty
Catalytic Oxidizer
Low-to-medium concentration streams; space-constrained plants
Wet Scrubbing
Pretreatment for explosive risk, sticky dust, acid/alkali gases
How we turn coating & surface finishing exhaust data into a treatment train
The recommended configuration is built around the actual production process, not a generic industry label. This is especially important when one site has multiple exhaust headers, recipes or operating modes.
Common treatment challenges
- Overspray and sticky aerosol upstream of VOC treatment
- Intermittent booth loading
- Mixed solvent systems across product lines
Data we request
- Exhaust source, airflow and operating schedule
- VOC/pollutant analysis, concentration range and LEL information
- Temperature, humidity, dust, mist and corrosive components
- Existing collection or pretreatment equipment
- Emission target, layout, utilities and shutdown constraints
Engineering decisions
- Whether streams should be segregated, balanced or treated together
- Which pretreatment protects downstream equipment
- Whether concentration, direct oxidation, recovery or polishing is appropriate
- Materials, safety interlocks, monitoring and maintenance access
- Where recovered heat or utilities can be integrated
Recommended path for coating & surface finishing exhaust
This is a decision framework based on the supplied product and project material. The final train changes with measured chemistry, operating patterns and site constraints.
Common emission sources
- Spray booths and paint-mist exhaust
- Flash-off and curing ovens
- Adhesive/UV coating stations
- Solvent cleaning and mixing rooms
Source capture → paint-mist pretreatment → concentration or direct oxidation
Paint mist and sticky aerosol must be controlled before adsorption or thermal/catalytic equipment. The oxidation route follows airflow, solvent load, operating schedule and heat demand.
- 01Balance booths and oven exhaust
- 02Remove overspray and particulate
- 03Assess concentration or direct oxidation
- 04Apply engineered destruction and safety controls
- 05Monitor operation and preserve maintenance access
Wet pretreatment + catalytic oxidation
Consider for compatible, clean-enough low-to-medium concentration streams where catalyst protection and liquid/wastewater scope are defined.
Process-specific questions
Why is paint-mist pretreatment essential?
Mist can foul a rotor, carbon bed, catalyst or regenerative ceramic media. Pretreatment is selected from the coating material, loading and gas temperature.
Can one system cover every booth?
Sometimes, but diversity of operation and different exhaust chemistry may make stream grouping or separate trains more reliable.
