- High Separation Efficiency: Micro-bubble flotation captures oil droplets as small as 10 microns, achieving suspended solids and grease removal rates above 90%.
- Robust SS304 / SS316L Construction: Thick-walled stainless steel tank walls, baffles, and scrapers resist the corrosive attack of oily, slightly acidic, or saline waste streams.
- Automatic Sludge Scraping: A motor-driven chain scraper continuously sweeps the floating sludge blanket into a collection hopper, eliminating manual skimming and reducing labour costs.
- Precise Pressure Saturation: A dedicated dissolved-air vessel maintains 0.4-0.6 MPa saturation pressure, guaranteeing a consistent 30-40% recycle ratio and stable bubble generation.
- Small Footprint, High Load: High surface loading rates of 5-10 m³/m² per hour let the unit treat large flows within a very compact tank volume.
- PLC Integrated Control: A PLC with HMI coordinates the air compressor, recycle pump, and scraper, with remote monitoring ready for SCADA integration.
