Wet Scrubber System Troubleshooting: 9 Field Fixes for 95% Uptime
Low ΔP below 2.5 mbar, ΔP above 15 mbar, or pH outside 5.5–6.2 cuts SO₂ removal by 15–20% on lime/limestone wet scrubbers. Restore L/G near 0.9 L/m³, acid-wash scaled headers online, and recalibrate pH probes every 48 hours. EPA guidance places typical wet FGD pH at 5.0–6.0 with 90%–99% SO₂ removal when contact and chemistry hold.
DAF vs API Separator: Which Is Better for Industrial Wastewater?
DAF removes 90–97% TSS and 85–95% FOG including emulsified oil, while API separators remove about 80% free oil and 50–60% TSS but cannot treat emulsified droplets below 150 µm. Choose DAF for limits under 10 mg/L oil or tight footprints; choose API for free-oil streams with available land. Capital, energy, chemical, and payback ranges are compared for a 50 m³/h duty.
