4. Conclusion
The organic matter degradation by microorganisms played a
leading role in the process of organic matter removal in the water;
this effect was indirect, emerging through the adsorption process.
The continuous removal of organic matters depended on the
microbial metabolic activity. The nutrients that can be used by
activated sludge microorganisms in their growth process were
the organic matters adsorbed to the microorganisms’ surface;
and not directly related to the organic matters in the water; thus,
the organic matters in the water must be first adsorbed onto the
surface of microorganisms, and then utilized in the microbial
metabolism.
