Recovery of nitrogen from saponification wastewater by struvite precipitation
Water Science and Technology, 2010 In general, saponification wastewater produced from the separation process of rare-earth elements contains high ammonium concentration. In this study, a series of experiments were conducted to investigate the parameters to enhance the struvite precipitation potential for ammonium removal from the wastewater having an ammonium concentration of 4,100 mg ...

Optimization of Struvite Precipitation for Landfill Leachate Treatment
, 2017 Sanitary landfill is the most preferred municipal solid waste disposal method. The production of highly polluted leachate is a major disadvantage of sanitary landfills. In this study, optimization of struvite precipitation to remove ammonium from landfill leachate was conducted by using Response Surface Methodology (RSM) and Central Composite Design ...
