| Abstract: | The activated sludge has been acclimatized with chromium (VI) ions from 5
mg/L to 20 mg/L. It is observed that the chromium removal percentage, COD
removal and mixed liquor suspended solid (MLSS) decrease with the increase in
dilution rate. Maximum food to microorganisms ratio (F/M) is found to be 0.19.
When initial metal ion concentration increases from 5 mg/L to 20 mg/L, the
chromium removal decreases from 95.58% to 63.85% (dilution rate 0.041h-1). |
