In present article the treatment of SIWW using iron electrode has been investigated. Various parameters viz, effect of initial pH (pHi), electrode gap (g), current density (CD) and treatment tine (tR), on COD and color removal efficiency have been presented. It is important to separated sludge contain in treated effluent, thus its separation by settling and filtration is also been presented. Economic point of view energy consumption and electrode loss has been estimated.
