5. Wastewater Treatment Chemical

★ Decoloring Agent (LT-Decol 10/15)

♧ Feature

1. LT-DECOL10 is a manageable solution type of
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.

4. The condensing effect of LT-DECOL10
can be highly promoted if inorganic flocculanting agent
(Aluminium Sulphate, PAC, Ferric Chloride, Ferrous Sulphate)
and high polymer flocculating agent
(Polyacrylamide, Polyacrylic polymer, etc.) are applied together.


♧ General Method

The flocculating efficiency of this agent can be influenced
by several conditional reaction such as types
and amounts of contaminated substances in waste water
and treating process, especially, waste waters in dyeing materials,
processing method, type of dye colors, etc.,

Therefore, the best condition of using method
should be appropriately controlled by waste water properties.


♧ Application

All types of sewer and colored waste from factories including :
- Dye works, painting and leather industry.
The oil, fat and petrochemical processing plant.

- The paper mill, metalworking
and meat processing industry. Properties

★ Fluorine Treatment (DYC-450)

DYC-450 takes care of wastewater functionally.
It is a high-density treatment for water that contains fluoride that
differs from existing calcium hydroxide
or sulfuric aluminum oxide joint-use treatment.

2-3ppm minimum density treatment is available
for SiF6 2-, BO3 2-/F- containing wastewater.

In particular, it presents excellent clearing effect,
which may be able to partially or
completely replace various inorganic agglutinates.


♧ Feature

• Highly dense fluoric ion treatment
under broad PH territory is available (PH 5.8-12)

• Replaceable with calcium hydroxide
and Alum joint-treatment process

• Alum 1/10 density compared with existing Alum

• Excellent clearing effect that doesn’t require
other inorganic agglutinates

• Compact process and non-sludge effect realized (cost-effective)

• Completely automated with liquid type

• Non-Heavy Metal


♧ Physical and chemical features

• Major ingredient:
Cation type Metallic Activated Catalyst & Inorganic Salts

• Form : Light Yellow-Brownish Color Liquid

• PH (at 20℃ , 1%) : 4.00 ± 0.5

• Specific gravity (at 20℃) : 1.35 ± 0.05

• Flammability : none

• Solubility: Complete


♧ How to use

• Inject to Auto Chemical Feed pump with undiluted solution
or optional dilution density (2:1)

• The injection density is generally 100-500ppm, exact density setup is
available with Jar-tester according to the water quality containing fluorine.

The good injection location is where there is whirlpool
and contact time is longer.-20 ± 2.0


♧ Caution

• The product is nontoxic, but avoid touching eyes, nose
or mouth since it is weak acid.

• Wear gloves when using and wash with clean water
when there is contact to skin.

• Clean with water immediately when spilt to floor since
it makes the floor slippery.

• Do not mingle with alkaline product,
and avoid long-term storage more than 6 months.


♧ Package

- 20L PE barrel, 200L Drum, 1m3 tote bin

★ Sedimentation Agent (Bio Chito -153)


♧ BIO CHITO's biochemical characteristics

• Solid enzyme compound with highly active bacteria and Chitinase,
the major decompostion enzyme of chitosan.

• A high density enzyme consisting of protease alylse, RIpase,
and chitinase.

• Since it is a liquid enzyme, remove the BOD and COD
from the solution by performing powerful digestive decomposition,
such as fat, oil, maintenance, protein, starch,
and issolved cellulose, using underwater activity.

• Identification of processing efficiency is
a visually oriented solid enzyme.

• All enzymes are removed by Chitinase
and returned to the Microbiology Center.


♧ BIO-CHITO's physical property
• PH(neat) : 4-6
• Appearance : A clear liquid


♧ BIO-CHITO's action

• If problems occur at the handling area, take prompt action.

• It improves the quality of waste water that is poorly treated
due to overload and low load.

• Remove the metal and heavy metals from waste water with
a strong chleating bond to nearly 100 % absorption.

• Remove SS, BOD, and COD during abnormal operation.

• Provides strong early treatment and prevention of SV reduction,
MLSS increase, and Bulking in a phenomena aeration Tank.

• Increase the efficiency of the insufficient sedimentation
Tank's capacity for treating microorganisms more than twice.


♧ BIO-CHITO's used method

• The place to put it directly into the final aeration Tank
or transfer it from the final aeration tank to the
second sedimentation tank.

• Adjust the input between two and five times,
depending on the type of cohesion,
by stirring the dilution rate twice to five times.

♧ BIO-CHITO's applied range for microbial treatment

• In case of frequent problems when repairing the final enffluent water

• Overload waste water due to low capacity.

• Waste water that is difficult to dispose of due to problems
with the aeration tank

• Waste water that is leaked from SS floates caused
by mold fungi in sedimentation tank.

• Waste water that blocks microbial activity
with biodegradable materials

• waste water is not good microbial activity.

• Waste water that is not always suitable for the
effluent quality standard

• Waste water that is not active due to insufficient microbial
and natural resources

• Waste water that is active in a short period of time
and that needs to be settled
and stabilized as initial and fineral seeding time.

• Application : Food, paper, leather, dye, fibre, printing, butchering,
livestock, sewage, etc.
