N2  - A pilot-scale aquatic primary treatment pond system was  carried out using two major plants namely, water hyacinth and  azolla to treat AIT campus wastewater under directly comparable  conditions .  In the first period, three parallel channels were separately  stocked with azolla nilotica as first pond; water hyacinths as  as second pond and control (without plants ) as third pond at a  mean BOD loading o f 94 kg BOD/ha.d and HRT of 9 days.  In the second period, three separate channels were stocked  with combined water hyacinths and azolla nilotica as t h e first  pond, water hyacinths as second pond a nd control as third pond at  mean BOD loading of 89 Kg. BOD/ha . ct. a nd HRT of of 8 days.  All experimental results revealed t hat the water hyacinth  pond showed an over-all superiority in treatment efficiency  followed by azolla and control pond s for both period s.  However, an increase in treatment efficiency was observe d with  azolla- water hyacinth pond in the second period compared with the  azolla pond in the first period
