- Abstract:
- A large-scale seawater desalination project in Iran adopts the high-speed air flotation process, which uses special technology to increase dissolved gas efficiency to over 95%, greatly improve the volume concentration of micro-bubbles, create more reasonable bubble size and the stronger dispersion ability. The surface load of flotation separation zone can reach 20-25 m3/(m2·h), the removal rate of algae in seawater can reach more than 95%, the effluent turbidity is less than 5 NTU, and the organic pollutants, oil and other pollutants in water also have good treatment effect. As the pre-treatment of membrane desalination process, high-speed air floatation obviously improves the operation condition of the latter process, guarantees the safe and stable operation of membrane system, and extends the chemical cleaning cycle of ultra-filtration membrane system to over 6 months.
