摘要：
An artificial PO43-, Mg2+ and NH4+ ions-contg. wastewater was treated with aq. soln. of NaOH in continuous flow to recover struvite by reaction crystn. at 298 K and pH 9-11 for 900-3600 s. The solid product contained struvite (90-95% by mass) and some impurities copptd. from the wastewater. The struvite crystals were 12-44 mu m in size. Their linear growth rate was (4.21-16.9).10(-9) m/s.
