Recently, our company has sent 15 cubic meters per hour dissolved air flotation to Chile for apple puree wastewater treatment, mainly to remove suspended solids in the water and reduce the burden on subsequent biological system. The floating scum separated by DAF is then sent to filter press dewatering machine to achieve the goal of sludge reduction.

This DAF system use Multi-phase flow pump to generate micro & nano bubbles without air compressor. The bubble liquid generated by the multiphase flow pump enters the air flotation reaction tank, and the microbubbles are adhered to the suspended solids particles as the carrier. By using the density difference between the air and the liquid, the pollutants float to the water surface to form scum. The scum is scraped by the scum scraping mechanism to remove oil and suspended solids and realize solid-liquid separation.

Compared with traditional DAF, SEPARATE Multi-phase flow DAF has the following advantages:

  • The air flotation equipment using Germany original imported multiphase flow pump, in the process it can achieve a very perfect effect, when the liquid and air is sucked from the inlet of the pump, air in a highly dispersed state achieves a complete mix with liquid, the solubility of the liquid dissolved air can reach 100% saturation state, the air exists in the microbubble dispersion state in the liquid, the average diameter of the bubble ≤ 26 microns; 

  • Liquids with air content of up to 30% can be transported stably;

  • Eliminating the need for compressor, pressure vessel, releaser, control system and valve, centrifugal pump) compared to conventional air flotation systems, which are greatly simplified and more reliable.
