★ 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.
