Treatment of semiconductor wastewater by chemical precipitation was investigated.

Removal of fluoride by Mg2+ showed good performance.

Fluoride ions exert a significant inhibitory effect on struvite crystallization.

Bittern is suitable to treat semiconductor wastewater.

PO4-P and F can be efficiently removed using the two-stage precipitation process.
