Bag and cartridge filters rely on physical media that fine, sub-1µm particles can pass through — and wet or sticky particulate can blind the media entirely. A WESP uses electrostatic charge rather than a physical barrier, so it captures particles down to 0.01 micron, including wet and sticky emissions.

The collecting electrode is cleaned through an automated spray-wash cycle rather than manual media replacement, which is the main maintenance routine that differs from bag or cartridge systems. We’ll walk through the maintenance schedule as part of your technical quote.

Yes — WESP systems are commonly installed as a polishing stage after existing cyclone or bag filtration, or integrated with other pollution control equipment already on site.
