Pre-Start Inspection
Begin with a comprehensive inspection of the High Speed DAF system. Check all mechanical components including pumps, valves, air diffusers, and sludge scraping mechanisms to ensure proper alignment and secure mounting. Verify piping connections are tight and leak-free, with correct flow direction. Inspect electrical systems to confirm proper wiring, grounding, and functional safety interlocks.
-
Instrument Calibration
Calibrate key instruments and control systems. Set flow meters, pressure gauges, and level sensors to accurate readings using calibration standards. Program the control panel with target parameters including influent flow rates, retention time, and chemical dosage rates based on wastewater characteristics. Test automated functions to ensure proper response to control signals.
-
Hydraulic Performance Test
Conduct a water-only test to evaluate hydraulic performance. Gradually introduce clean water, monitoring flow distribution, mixing intensity, and water level stability. Check for short-circuiting or dead zones. Verify that the flotation process generates a stable bubble layer and that sludge is properly collected and discharged.
-
Wastewater Introduction
Introduce actual wastewater in a controlled manner, starting at reduced flow rates. Monitor key performance indicators including suspended solids removal and oil separation. Adjust chemical dosages incrementally to optimize floc formation and bubble attachment. Record operational data to establish baseline performance.
-
Safety & Documentation
Perform safety checks and staff training. Ensure emergency shutdown systems function correctly and that operators understand safety protocols. Document the commissioning process including adjustments made, test results, and final operating parameters for future reference.
