The suspended growth processes use several process modes that range

The suspended growth processes use several process modes that range from “conventional, contact stabilization, single sludge, extended aeration and sequencing batch, which are present for polishing effluents that are anaerobically treated” (EPA 2004). Suspended growth processes are ideal for “industrial plants, steam systems, heating and cooling systems, swimming pools, cooling tower systems and domestic water supplies” (Surampalli 2004).

The suspended-growth processes are operational in lesser space than the attached growth processes. However, compared with the attached growth process, suspended growth processes are not able to put up with radical changes in the quantity of biological material. In addition, they lack the capability to provide higher elimination rates for organic material and suspended soils (EPA 2004, 11-13). The suspended growth water systems do not have a high concentration of active biomass as a result of microorganism mobility. Low temperatures have not been found to have a minimal negative effect on nitrification as compared with attached bio-film growth systems.
