Wet Electrostatic Precipitator (WESP): The Last Barrier for Ultra - low Emissions

When regulations require particulate matter emissions to be less than 10 mg/Nm³, mechanical and bag filtration reach their limits. This is where Haina's Wet Electrostatic Precipitator (WESP) comes into play.

Our WESP is designed for harsh environments—including waste incineration, chemical processing, and high - humidity flue gas—it has the following features:
Up to 90% removal efficiency for fine particulate matter PM2.5

Continuous operation without secondary dust re - entrainment

Compatible with fiberglass reinforced epoxy resin (GRE) or duplex stainless steel 2205 dust collection tubes

Our system is powered by a high - frequency switching power supply from Shanghai Leishuo, which achieves faster voltage rise, better arc suppression, and saves up to 30% of energy compared with traditional transformers.

Recent installations in Indonesia and Bangladesh show that even when the inlet concentration exceeds 30 mg/Nm³, the outlet concentration can continuously remain below 5 mg/Nm³.

Application Scenarios: Customers facing third - party monitoring, located near residential areas, or preparing for a third - level environmental certification.
