Abstract
The removal of COD from dairywastewater was experimentally investigated using direct current electrocoagulation (EC). In the EC of dairywastewater, the effects of initial pH, electrolysis time, voltage and different electrodes were examined. The optimum operating range for each operating variable was experimentally determined. The greatest removal efficiency was obtained with the use of aluminium as anode and iron as cathode (Al–Fe system). The batch of experimental results revealed that COD is effectively removed. An efficient algorithm is developed and coded in MATLAB to calculate the corresponding COD for given input (pH, time, voltage).
