    Abstract

    <>Filamentous and non-filamentous micro-organism digest organic matters in wastewater for living.  Some of micro-organism is an index of the water quality if found some types of  micro-organisms that have high efficiently digesting organic matters in wastewater. The environment in wastewater have effected to filamentous and non-filamentous micro-organisms such as chemical substances, pH, temperature and organic loading. The purposes of this research are; classification of filamentous  micro-organism taken from wastewater treatment plant at Double A Pulp&Paper Mill in Thailand, determination the index of water quality by numerical scoring and verbal scoring  filamentous organisms in activated sludge bulking  and  selection the best indicator for water quality of Double A Pulp&Paper Mill wastewater treatment plant. The results of testing showed that the microorganisms in sludge foaming such as S. natans, Types 021N, Thiothrix and Beggiatoa. The numerical scoring and verbal scoring filamentous organisms from the experiment showed that the dominant type of filamentous bacteria was S. natans in Excessive verbal scoring.
