Electrode A/V Ratio - Electrode area to volume ratio is an important parameter in EC plant design. It typically varies between 100 and 1000 cm2/L. An increase of A/V ratio results in a decrease of treatment time.
To increase current flow between the electrodes, the distance between the electrodes should be reduced. This can be done by increasing A/V ratio.
Increasing conductivity or TDS of water also results in a increase of current flow between the electrodes. NaCl is frequently used to increase the electrolytic conductivity or TDS of water.
The optimum electrodes distance typically is in range of 1cm to 2cm.
The electrode material can be optimised by using more no. of electrodes in series. This will save upto 50% electrode material.
Current density is a key parmeter of EC. The optimum current density should be determined considering other operating parameters. The suggested current density for efficient operations is to be in between 2.0 and 2.5 mA/cm2
