3.1 Comparison of Removal Efficiency of Nitrate
for Different Batches
Figure 4a, b shows the variation of removal efficiencies for bio-balls and corn cobs
as media for different concentration of nitrate and different operating time. For
both the media, removal efficiency increases with increase in concentration and
increase in operating time. For bio-balls, with increase in concentration from 15 to
