Description
Summary:The feasibility of using activated carbon to improve the efficiency of petrochemical wastewater treatment was assessed. The effects of passing secondary effluent through columns of granular activated carbon (GAC), and of adding powdered activated carbon (PAC) to the aeration tanks of the activated sludge process were both investigated. The PAC system did not significantly reduce colour and was less effective in removing COD. The GAC system produced a colourless effluent with less than 150 mg COD per litre, and reduced organic priority pollutants to below detection limits.
