Description
Automobile spraying workshop
The spraying and painting industry uses a large number of organic solvents and dyes, whose molecules are usually polar molecules. After being modified and loaded with electron-rich polar groups, activated carbon has efficient and specific trapping ability for pollutant molecules with large dipole moments. Besides, heavy metal ions are contained in waste liquid, activated carbon creatively loaded with carboxylic acid or alkoxy group has the ability to selectively coordinate and complex the metal ions in the water.

Case
VOCs treatment in the spraying workshop of a joint venture car company
Problem: non-methane hydrocarbons concentration 800 mg/m³, exceeding the limit value 120 mg/m³ GB 16297-1996.
Solution: adopt honeycomb AC + RCO system, airflow of 200,000 m³/h.
Effect: Emission concentration reduced to 15 mg/m³.

Case
Problem: epoxy primer spraying releases Bisphenol A (concentration up to 15 ppm), far exceeding the EU limit (≤ 0.01 ppm).
Solution: adopt modified AC adsorption tower, combined with UV ionization monitor.
Effect: BPA removal rate >99.5%, stable emission concentration <0.005 ppm.
