AbstractThe study of the removal of organic matter, ammonia nitrogen and suspended solids in a compact RBC-Settling tank system is described. Different concentrations of synthetic wastewater were fed parallel into four 4 - stage laboratory scale cascade - connected RBC-Settling tank reactors, at a fixed rotational speed and hydraulic loading. The results of the systems are presented in terms of ammonia , organic and suspended solids loading and removal using the new concept of Disc Biomass Index , Sludge Biomass Index and soluble chemical oxygen demand were more than 95 percent. A MONOD liked hyperbolic function equation fit well for the experimental data, and it gives a reasonable good prediction for the organic removal rate in stage one.
