Boron Removal from Mining and Synthetic Effluents by Electrocoagulation Using Aluminum Electrodes

Table 5

Comparison of operational cost in the electrocoagulation (EC) and chemical coagulation (CQ), during 60 minutes for synthetic effluent and, for mining effluent, 90 minutes, using current density of 14.42 mA cm⁻² in the EC.

Effluent	EC-cost (US$)	CQ-cost (US$)	Boron removal EC (%)	Boron removal CQ (%)
Synthetic	0.191	0.343	60.9	24.1
Mining	0.245	0.469	69.0	12.7
