Abstract

Intermittent aeration has been proved to be an efficient method in nitrogen removal in many biological treatment processes. Aerated lagoon has been used as domestic wastewater treatment for a small housing estates in Thailand for quite sometime. The purpose of this study is to determine whether intermittent aeration of aerated lagoon could provideefficient nitrogen removal in domestic wastewater. The experiment wascarried out using pilot scale aerated lagoon at Chiangmai University. The result showed that 45% of total nitrogen removal could be achieved by aeration and non-aeration of 12 hours each cycle. The intermittent aeration did not affect organic substances removal of the process. Sludge recycle during non-aeration period may improve total nitrogen removal. The method could be introduced to save energy of small wastewater treatment plant.
