Biological Treatment
For the suspended or dissolved solid organic content present in biological treated waste water to be decayed by bacteria, and to convert to stable inorganic components as gas that run to the atmosphere or stay in the fluid with settleable biologic flocks.
The principal of biological treatment is iterating of the control of processes of bioflocculation and mineralization for destruction of organic impurities, within the environment and optimal conditions. So that, the natural reactions are accelerated and performance in safety environment is provided. The biological treatment can be classified differently. These systems classified as airy (aerobic) and un-airy (anaerobic) according to the environment’s oxygen amount, can also be classified suspended or stable film (bio-film) processes according to the situation of the microorganisms in the system.
