Abstract
PVA gel beads are proven out to be an effective structure for enrichment of large number of bacteria, providing high nitrification rates at lesser filling percentages. The treatment configuration (oxic–anoxic–oxic along with a settler) has shown a characteristic balance of nitrogen and alkalinity through the nitrification and denitrification phenomenon in the tanks. Ammonia removal rates were >90%, organic matter removal (COD) was 87–96%, and TSS removal was 96–99% at variable HRTs (6, 5, and 4.4 h) and temperatures. Total nitrogen balance was figured out as, average TN was 4.507 g/d in inlet, out of which 0.121–0.526 g/d (2.69–11.67%) get into the waste sludge, 0.191–0.947 g/d (4.25–21.01%) remained in the outlet, and the rest 3.077–4.151 g/d (68.27–92.11%) was removed. Accordingly, alkalinity balance showed that 25% of the inlet alkalinity was consumed in overall nitrification and denitrification process.
