In the processes of wastewater treatment, significant amounts of iron phosphate containing sludge is discharged. One of the recycling methods of this sludge, alkalization treatment is investigated. aq. solution of sodium hydroxide is added to the dehydrated sludge. Iron phosphate in the sludge react with sodium hydroxide, forming sodium phosphate and iron hydroxide containing-sludge at room tem...
