Abstract
The CellCaSi, a porous silicate material, was tested for the removal of phosphorus(Pas phosphate) n water. The effect of the CellCaSi was investigated on the basis of both particle size(under 1, 2 and 4㎜) and added amount(0, 1, 2.5, 5, and 10g/ℓ) of the CellCaSi. The removal efficiency of phosphorus was highest with a particle size of under 1㎜ and also increased with an increasing amount of the CellCaSi. The pH change showed little effect on the phosphorus removal of the CellCaSi. The calcium ion was eluted from the CellCaSi into the water, while the aluminium and iron were not. The eluted calcium ion was combined with dissolved phosphorus and then precipitated. The highest removal efficiency of phosphorus was obtained by the combined addition of the CellCaSi, calcium chloride, and ferric chloride. That is, the phosphorus concentrations of 0.10 and 1.0 ㎎/ℓdecreased to 0.03 and 0.47 ㎎/ℓ by the addition of the CellCaSi(1 g/ℓ), calcium ion(30 ㎎/ℓ), and ferric ion(1 ㎎/ℓ) at day 8 after treatment. The water qualities at the end of the experiment were as follows:pH was 8.1 and conductivity was 318 S/㎝ for raw and potable waters).
