Removes 90% in 24 hours
Cost Effectiveness
1 g can treat 1 to 5 tons of water
Reducing treatment costs compared to other products on the market
Convenience
No need for a secondary process to remove
flocculated algae required by other products on the market
Safety
Uses biodegradable organic materials instead
of heavy metals for a higher level of safety
have confirmed the safety of our product on over 20 species of organisms.)
Applications
Case 1. Field evaluation of the effectiveness of algae removal in shrimp farms in Ujung Kulon, Indonesia (2016)
[Ujung Kulon, Indonesia]
By reducing harmful algae, the water around the water wheel
becomes much clearer,
allowing the wheel to run smoothly and increasing shrimp
survival rate.
High Algae Removal Efficacy of
GreenTD ®
Case 2. Field evaluation of the effectiveness of algae removal at Bongrim Reservoir in Yesan- gun, Chungcheongnam-do (2022)
[Point A (Inlet)]
[Point B (Intake Tower)]
Algae removal was evident 5 hours after treatment,
and chlorophyll measurements one day after treatment showed fast
and high algae removal efficacy of 72 to 89%.

Heavy metals analysis (FITI Testing & Research Institute)
No traces of copper, lead, nickel, arsenic, mercury, zinc,
cadmium, or chromium have been detected
(GreenTD 1,000 ppm, based on standard water quality test)
03
Toxicity Assessment for Oryzias and Artemia (Major Feed for Marine Lives)
* EC₅₀ : The parameter EC50 abbreviates for half maximal effective concentration. The EC50 is the concentration of a drug that is necessary to cause half of the maximum possible effect.
** NOEC : The parameter NOEC is the concentration of an active ingredient in an environmental medium that will not produce any adverse effect.
04
To ensure safety, additional human toxicity and genotoxicity studies have been conducted by publicly authorized test laboratories.
