Palm Oil Factory Wastewater Treatment Using Electrochemical Technique

A study was carried out to determine the suitability of palm oil factory wastewater treatment using electrochemical technique with stainless steel as both working and counter electrode in 0.1 M NaCl. Treated liquid samples were later analysed using UV-Vis and COD determination. While solid samples formed during the electrolysis process were analyse using FTIR and CHNS analyser. Results obtained showed than electrochemical technique with the above condition able to reduced color and COD level of the wastewater up to 50 % and 80 % respectively after 3 hour electrolysis time with 10 V applied voltage.
