The suspended growth process speeds

The suspended growth process speeds up the work of aerobic bacteria andother microorganisms that break down the organic matter in the sewage by providing a rich aerobic environment where the microorganisms suspended in the wastewater can work more efficiently.In suspended growth processes, the microbial growth is suspended in an aerated water mixture where the air is pumped in, or the water is agitated sufficiently to allow oxygen transfer.The purpose of disinfection in the treatment of wastewater is to substantially reduce the number of microorganismsin the water to be discharged back into the environment and is almost always the final step in the treatment process regardless of the level or type of treatment used.
