Study of the Efficiency of Using Various Calcium-containing Reagents for Wastewater Dephosphorization
The efficiency of application of calcium-containing reagents (calcium oxide, calcium hydroxide, calcium peroxide) for removal of phosphate ions from waste water was evaluated. It has been established that calcium oxide (99,78 %) and calcium hydroxide (99,80 %) were the most effective ones for dephosphorization; the efficiency of calcium peroxide was 90,0 %. The changes of COD and pH indicators depending on the concentration of dephosphorizing reagents added to wastewater were experimentally investigated. Conclusions about the efficiency of calcium-containing reagents application are formulated.
