The combination of electroflotation-biocoagulation process using Aloe vera for river water treatment

Abstract

Abstract An evaluation of the combination of electroflotation-biocoagulation performance using Aloe vera as biocoagulant in the treatment of river water has been conducted. Titanium electrodes were used as anode and stainless as cathode in the electroflotation reactor, with a 20 V DC of constant voltage for 30 minutes. The parameter dose of Aloe vera was 1.0, 1.5, and 2 g/200 mL water. The effectiveness of the electroflotation-biocoagulation process was reflected by the measurement of turbidity, total dissolved solids (TDS), pH. The results showed that the electroflotation-biocoagulation process decreased the turbidity as much as 97%, TDS as much as 82.64%, and changes in the pH value to 6.6 from the initial concentration of water.
