HOW DOES IT WORK

Increase beneficial bacteria population in the pond

Suppress harmful and pathogenic bacteria population

Decrease F/M ratio increase digestion rate of organic

matters

Accelerate the digestion of oil, fat, grease

Phototropic bacteria will suppress the bad smell of

ammonia and hydrogen sulphide. Slow release treatment

BioDango Ball contains microbes that will slowly release

to treat the water condition and sludge from the bottom

of the pond

This will provide continues treatment since BioDango

Ball will stay at the bottom.

THERE IS NO DISLUDGING WORK WILL BE DONE

ONLYBIOLOGICAL TREATMENT PROCESS

HOWDOESOURPRODUCT

(BIOSENSE)CONTROLODOR?

The microbes in our product attack the cause of the

pond odor, ammonia and slow decaying organic

matter

By accelerating and stabilizing the natural nitrogen

conversion reactions, our product BIOSENSE

greatly reduces or eliminates the release of ambient

ammonia. Rapid digestion of accumulated organic

matter eliminates foul odor.

CHALLENGES

Uncontrolled pollutants (chemical discharge/oil

spillage) discharged from workshop and shops

Abnormal activities such as illegal waste disposal intothe river

Uncertainty of heavy rain and flash flood
