The effluent from product processing and refining plants contains phenol and phenolic compounds which are harmful and toxic in nature, requires a great attention in wastewater treatment. The study was focused on ozonation process for the reduction of phenolics and chemical oxygen demand (COD) at certain time interval by varying pH. Ozone is a strong oxidizing agent, the reaction of it with organic and inorganic ions in aqueous media has achieved a verity of treatment goals. Ozone is a safe alternative to chlorine products which performs the same functions without the undesirable side effects, it is not harmful to the environment since it is made from oxygen and decompose back into oxygen, no sludge disposal problem and increase the dissolved oxygen content of wastewater which helps further in the degradation of residual pollutant. Ozone generator was used for the treatment of phenolic wastewater. Experimental study was performed on synthetic wastewater which containing 200mg/l phenol concentration at different pH conditions for 6hrs of ozonation. The maximum 96.04% phenol removal was found after 4 hours of ozonation and maximum 65.08% COD removal was found after 6 hours of ozonation at pH11. The overall study showed that the alkaline pH was more favourable for better phenol and COD removal.
