poly cationic flocculating agent.

2. LT-DECOL10 has a new form of chemical structure which
removes anionic soluble substances and suspended particles
in the sewer and waste water congealed by extraction,
thus making insoluble composition with superior condensing and
disintegrating effects through the reaction of physical chemistry.

3. This product is very effective in treating industrial waste water,
solution and sewing containing COD substances hard to disintegrate.
Especially, it can be most effectively used for decoloring waste water
and removing active agent in dye works.

★ Microorganism Activator (Bio-Most N205)

The BIO-MOST provides with high quality nutrition for rapid
multiplication to existing microorganisms,
and especially applies to wastewater in which the BOD, COD is
not balanced to activate sludge. (Sludge Activator)


♧ Product specification
• Bio most N102 (Customized product,vaccination)
• Bio most N205 (High activator, vaccination)
• Bio most GN200 (MLSS increaseing active sludge nutrient, vaccination)
• Bio most L101 (Odor remove, vaccination)


♧ Features

1) Ingredient :
Active Bacteria, Carbon, nitrogen, inorganic mineral, hexane base, etc.

2) Form :
Bio-Most N series(Pale yellow powder), Bio-Most L series(liquid)
The multiplication of microorganism Microorganism proliferates
very quickly, repeating segmentation within 30 minutes to a few hours.

The numerical value of proliferation when generation time is
30 minute is 2.8×1014 in 24 hours.


♧ Factors obstructing microorganism multiplication
The microorganism that exist in aeration tank proliferates
in the process of ingestion and disintegration.

When we look at the reason why active sludge doesn’t proliferate,
it is due to factors such as relatively low COD in chemical wastewater.

This causes the obstructing factors such as temperature, pH, DO, etc.
Proliferation factors for microorganism When there is obstruction factor,
the activation rate falls. BIO-MOST provides with proliferation factors
and maintains the balance to activate sludge.

Inject 100 ~ 200ppm everyday for
5 ~ 10 days in the initial seeding stage.

Inject 10 ~ 40ppm to inflow quantity for
stable water quality management.
