2-1 What is OZONE for?
for Drinking water treatment

for Sewage water treatment

・ Improvement of odor, taste, color
・ Disinfection
・ Reduction of organic compounds
・ Reduction of trihalomethanes (THMs) precursor

・ Disinfection
・ Improvement of odor, color

・Ozone is effective in removing COD, SS and color from raw water.
・Whereas increasing O3 dosage decreases COD value, it increasesBOD value. This is because COD becomes biodegradable
substances through ozonation. Installation of activated carbon
posterior to ozone results in high-level removal of BOD .

NGT recommends more stringent standard including T-N and T-P reduction.
 Even existing plants are also recommended to modify within 7 years by NGT.
 Currently, most of the new STP construction projects comply with NGT recommendationlevel treatment.

4-2 Technical Summary
AT-BC system is one of the advanced wastewater
treatment system. It was developed integrating andevolving activated sludge process and rotating biologicalcontactor process.
Contactor in the AT-BC is reticulated structure (meshed),
it allows high volume of Bacillus sp. to stick and due to thehigh oxygen supply, and it enables effective removal ofBOD and Nitrogen.
What is Bacillus
Bacillus is a common soil bacterium, andcan be found everywhere around us.
By putting and growing Bacillus in the【Bacillus】
aeration tank, they strongly remove
COD, Oil & Grease, Nitrogen, etc. as well as BOD.
Bacillus is coexisting with conventional activatedsludge bacteria in the aeration tank, and will
demonstrate outstanding functions and effects.
