Powder Ca(OH)2 used in neutralization treatment of waste water have a problem that dust was severely generated when people used that. To solve this problem, we prepared Ca(OH)2 suspension having dispersion stability. Ca(OH)2 suspension having various particle size were prepared by mechanical dispersion using ball-mill. The longer dispersion time, particle size was the smaller. To improve dispersion stability of Ca(OH)2 suspension, sodium lauryl sulfate(SLS) and glycerol were added. Ca(OH)2 suspension evaluated as water treatment agents for removal of PO43- in pickling waste water. |
