Study of Treating High Ammonia-N Domestic Wastewater with CASS Process

The study of treating high ammonia-N domestic wastewater is in the initial stage at home. The removal rate of nitrogen is still at a low level. In the experiment, the CASS process was used to treat high ammonia-N domestic wastewater. The influence of these factors on nitrogen removal, including sludge load, reflux ratio, aeration time, dissolved oxygen and aeration time, were studied and discussed. And then find the optimum conditions.
