Abstract
Most of latex concentrate processing factories in Thailand discharge treated wastewater high in organic loading to the nearby rivers which can cause a serious threat to the environment. This study aimed to determine in batch e score mode the performance of ozonation as a pretreatment and/or followed by batch activated sludge process BAS for treatment of wastewater from rubber factory. The treatment was evaluated based on the biological oxygen quickly demand BOD5 ammonia nitrogen NH3-N and TKN removal efficiency. Wastewater was taken from latex concentrate process from the factory at Chonburi Province Thailand. The results showed that when using BAS without ozonation the removal efficiency of BOD5 COD NH3-N and TKN were 85.88 66.8 60.06 and 56.38 respectively. While with ozonation they were 95.79 91.49 74.75 and 67.95 respectively. It was observed that the removal efficiency for all parameters with ozonation as a pretreatment was significantly higher than that of without ozonation. The findings illustrated that the combined process can improve the performance of activated sludge process. Such combined processes were found to be very effective in removal of above mentioned parameters in wastewater and also produced a final effluent low in suspended solids and also clear as well as odorless. It was observed that the pungent odor of wastewater was significantly decreased after ozonation and completely disappeared after activated sludge process ASP.
