The îreaîabiîity of a paper miîî wastewater by adsorption and activaîed sîudge
methods \vas investigaîed. Alîhough a wastewater treatmenî faciîity, which ~works 'with coaguîationfloccvlalion

under îhe allo\vabîe vaîves ofthe Turkish Water Polîuîion Control Regulaîion. First, adsorpsion wUh
p(rwdered acîivaîed carbon experiments . were done. Since the required reduction ofCOD could not

conducled. This was aho not satisfacîory. Finaîly, activated sludge method vvas applied. it was' found
îhaî when the wastewater is not heavily polîuîed (COD<600 mg/l) activated sludge treatmenl is
