Fishery waste water often contains a high amount of organics that should be treated. In this research, fishery waste water was treated via electrocoagulation with dissolved metal electrodes. The samples were collected from some fishery processing sites in Da Nang city. The parameters influencing the COD removal efficiency such as the current density, the solution pH, the stirring speed were investigated.The results showed that the highest COD removal efficiency obtained was above 80% with a current density of 1mA/cm2. The fact that the solution pH equalled 7 was optimal for keeping the stabilization of the colloid and the high efficiency of the COD removal. The temperature from 30oC to 40oC and the recycled filter pumping of the waste water could improve the efficiency of the treatment.
