    Ammonium removal from wastewater via struvite pyrolysate recycling with Mg(OH)2 addition

    Magnesium ammonium phosphate (MAP) pyrolysate recycling technology was investigated with Mg(OH)2-mediated pyrolysis. The results revealed that the removal ratio of ammonium was stable at about 75%, and could be increased to 79% after additional acidolysis. The phosphate concentration in the supernate was low at 2 mg/L. The optimum conditions for ammonia release were a 1:1 molar ...

    In the MEL process, lime reagent, containing calcium hydroxide (Ca(OH)2) and magnesium hydroxide (Mg(OH)2), is used to react with the SO2.  As with the LSFO process, the hydroxide slurry is added to the recycle tank to replenish reagent consumed under pH control of 6 to 7.
