During the treatment process a amount of valuable biogas energy will be produced which can be collected for other usage;
Much less bio-solids waste generated compared with aerobic process because much of the energy in the wastewater is converted to a gaseous form and resulting in very little energy left for new cell growth;
A low energy requirement for the treatment process;
Less nutrients required;
System can be shut down for extended periods without serious deterioration; and
Can handle organic shock loads effectively.
