■ Moving Bed Bio-film Recator

IL SEUNG is the world's leading manufacturer of marine sewage

treatment systems. For over 10 years IL SEUNG's sewage treatment

plant have been widely regarded as standard specification on all

type of vessels.

IL SEUNG's own technology, "Moving Bed Bio-film Recator", has been

developed with previous sewage treatment plant to maximize the

contact surface of Microorganisms so it can treat sewage optimally.

■ Biological + MBBR

* Expanded surface to live microorganisms
* Microorganisms, increased rapidly
* Maximization of disposal capability
* Semipermanetly used
* Less sludge occured
* Durability at fluctuation of load

■ Process

#1 & #2 Tank, Biofilter Reactor
Raw sewage water first enters into the aeration tank. The tank is

aerated and mixed by air which is supplied via fine bubble aeration

elements. Required amount of air is delivered to the aeration

elements by the blower.
The tanks are filled with MBBR, which are optimized for the

activation of the microorganisms, so it can correspond to the

irregular sewage supply well.

#3 Tank, Settling Tank
The sludge deposited in bottom of the sedimentation tank. It

returns(Air lift pumping) to the sewage entrance section to break up

the organism mattters.

#4 Tank, Sterilization Tank
After inserting small amount of chemical to remove coliform,

sterilized treated water will be discharged automatically by level

switch.
