The biofilm exposed to air continuously contacts air and thus micro-organisms easily stick to the film
and become active. This makes the initial inoculation with micro-organisms very easy.
Furthermore, since micro-organism actively multiplies thanks to the sufficient supply of air, stable
water quality can be secured. In addition, thanks to the microorganisms growing being stuck to the
biofilm exposed to air, loss of microorganisms is very small. This makes the sludge age very long and
allows internal respiration of the microorganisms. This phenomenon sharply reduces the remaining
amount of sludge compared to the existing biological treatment process. By designing a separate tank
for treatment with nitrogen and phosphorus, not only organisms but also N.P ingredient can be controlled, satisfying the strengthened regulations on the water quality for discharge.
