文摘
- •
Phosphorus removal was demonstrated using sodium hydroxide coated slag.
- •
Coated slag caused high pH of the solution and increased the removal efficiency.
- •
When pH dropped below 8.0, phosphorus removal efficiency rapidly decreased.
- •
Ca, Mg, Al, and Na ions were consumed in the precipitation-coagulation process.
- •
Enhanced removal efficiency was obtained by recycling the initial effluent.
