EFFECTS OF CO-EXISTING ANIONS ON FLUORIDE REMOVA IN ELECTROCOAGULATION (EC) PROCESS USING ALUMINUM ELECTRODES

This study assesses the effect of three co-existing anions (Chloride, Nitrate and Sulphate) on defluoridation in electrocoagulation process. Monopolar and bipolar systems were operated in potentio-dynamic polarisation and defluoridation tests. Experimental work and methods are detailed and results are discussed.
