Electrochemical oxidation of fish canning wastewaters using SnO2 electrode [Oxydation électrochimique des rejets de conserverie de poisson à l'aide d'une électrode de SnO2]

The electrochemical treatment of industrial wastewater from a fish canning,located in agadir city,morocco,was performed efficiently using a sno2electrode. it was found that the temperature and current values must be optimized in order to reduce the energy costs of process. the raw effluent baseline characteristics with a temperature between 17 and 35 °c,the average ph values oscillating around neutrality and a high salinity,are useful conditions and lend themselves well to an electrochemical treatment. a cod removal rate of 77[%] was achieved with 35 °c,amperage of about 0,06a and an electrolysis time of 3 hours conditions; the power consumption was about 1 kwh.kg-1.
