Organic Removal of Pulp Wastewater Using Bench Scale Extended Aeration Activated Sludge System

A company located in Gurun, Kedah is currently producing a biodegradable
packaging that act as fertilizer for farm usage. The company currently using chemical
treatment plant to treat their wastewater which is quite expensive to operate and maintain.
This research was conducted to determine the feasibility and efficiency of treatment of
pulp wastewater from the production of processing rice straws and husks using bench
scale Extended Aeration Activation Sludge (EAAS) system in reducing the organic
constituent. The reactor was run few weeks with UTP domestic wastewater as the influent
for 3 weeks to acclimatize the sludge inside the reactor. The reactor was then fed with the
influent mixture of 20% industrial pulp wastewater and 80% UTP domestic wastewater.
