Abstract:

The waste stabilization pond operating at a loading of 250 lb resulted in a removal of 97.7 percent of BOD, 92.6 percent of COD, 84.2 percent of TOD, and 80 percent of TOC. The average enteric virus inactivation was 88 percent and 94 percent for the coliphage and animal viruses respectively. The bacterial dieoff was in excess of 98 percent for the total coliform, fecal coliform and fecal streptococcus. The introduction of high purity oxygen to waste stabilization pond systems increased the removal efficiency of BOD5, COD, TOD, and TOC in excess of 98.6 percent, 94.6 percent, 89 percent, and 90 percent, respectively at an organic loading of 250 lb BOD5acre-day. The inactivation of enteric viruses and dieoff of enteric bacteria also improved. Complete inactivation of the enteric viruses in the effluents of the bond systems was achieved at a chlorine residual of 0.5 mgl after 30 minutes of contact. Virus concentration with bentonite was effective in recovering approximately 50 percent of the virus.
