Colloide’s high rate Dissolved Air flotation (‘DAF’) unit has been developed using the most advanced solids/liquid separation techniques available.
The performance of our DAF unit is superior to that of similar or alternative technologies, both as a clarifier of primary or secondary effluent waters and as a thickener for biological sludge.
The simplicity of the design of the AQUA-DAF system is at the core of its high operational reliability and its remarkable versatility. The circular low head geometry of the cell, innovative hydrodynamics of fluids entering and exiting the cell, and the proven efficiency of the floating sludge removal system all contribute to the excellent performance of our DAF system.
Summary of the DAF process:
Applications include: wastewater treatment (primary and secondary clarification), sludge thickening, refinery oily wastewaters treatment, white water clarification/fibre recovery in the paper industry, surface waters clarification, algae removal, oil and grease removal and juice clarification in the drinks industry.
