Dissolved Air Flotation Machine

· Heavy metal ions in electroplating wastewater.
· Approximately 70% COD removal and 90% suspended solids removal in food slaughtering and leather processing wastewater;
· Reduction of oils and fats in petroleum refining wastewater to below 10 mg/L, achieving clear effluent quality.
· Treatment of chemical wastewater and paint/pigment effluents with approximately 74% COD removal and 93% color reduction.
· Recovery of approximately 95% fiber from paper mill white water with 86.7% COD removal, enabling full reuse of treated water.
·Turbidity in large-scale bathing water can be stabilized below 10 NTU, with significant reduction in bacterial content. Turbidity in potable and industrial water can be purified below 5 NTU, while also effectively reducing color and oxygen demand;
·The above data are empirical values for reference only. Actual results may vary.

This equipment employs the pressurized dissolved air flotation method. Its operating principle involves dissolving a large volume of air into water under specific conditions to form dissolved air water, which serves as the working medium. Through sudden decompression and rapid release, this process generates a vast number of fine bubbles. These bubbles adhere to the flocs formed in the wastewater after coagulation and flocculation, causing the flocculated particles to rise to the surface. A dedicated skimming device then removes the floating sludge and oil, achieving solid-liquid separation.
