Equipment configuration

Designed around actual process conditions

WESP is used where conventional filters and scrubbers cannot reliably capture sub-micron or sticky aerosol. Irrigated collection surfaces reduce fouling and support continuous industrial operation.

How it works

Particles and droplets receive an electrical charge, migrate to collecting surfaces and are washed into the liquid-management system.

  1. 01Cool and condition the gas
  2. 02Remove coarse loading in pretreatment
  3. 03Charge and collect fine aerosol
  4. 04Wash collectors and manage liquid
