- Microorganisms for biodegradation of PCP (pentachlorophenol), chlorinated organic
compounds and dioxin.
- Optimum Temp. 20 - 30°C
1. Applied Field of Industrial and Applied Businesses
(Applicable Business):
PCP (pentachlorophenol (timber antiseptic, agrochemical, insecticide)), dioxin, contaminated timber by chlorinated volatile organic compounds, soil, purification and restoration of wastewater, soil, industrial wastewater, waste, timber, underground water, organic soil, golf course related.
2. Present treatment methods and problems
Incineration but creates great amount of dioxin
3. Principal functions and expectable effects.
1) Environmental restoration by biodegradation technology of Pentachlorophenol
and
chlorinated compound which main source of dioxin 90~99%.
2) Restoration of environment that polluted by hard to decomposition harmful
matters with
bonding action of nature friendly bacteria.
3) Removing polluted PCP fundamentally by turning hard to decomposition
harmful
matters such as PCP to burning element for bacteria.
4) Biodegradation of dioxin for soil is excellent succeed example internationally.
4. Comparison with other product
It has superior effects than White Rot Fungi or Flavobactrium which has been sold at U.S.A.
5. Actual results and applied example: Registered at Patent details
1) Ammunition box: Treated 5 tons for Ministry of National Defense of Korea,
United
States Forces Korea. (Result of analysis: Dail Biotech)
Result: Initial density of PCP: 3,000~10,000ppm. After treatment: Decreased to 16ppm

6. Treatment Method
Depositional treatment by plant type tank or product input spray to the state of floating on the surface of water by binding to soil, sticks to alien substance or adhered to Timber: Stains travels and decomposition. Time period can be different depends on thickness but normally it requires about 2 months for insert spraying method and about one month for deposition mixing method.
