 Hydrogen Sulfide Treatise

 Material Safety Data Sheet




ALKEN CLEAR-FLO® 7139 contains an incomparable selection of twenty-four gram-positive Bacillus microbes to degrade hydrocarbons, either as a sheen on water or on a solid surface, such as a marina dock, while eliminating high concentrations of hydrogen sulfide and other noxious odors (except mercaptans). The microbial consortia is assisted by the nutrients and catalyst action of a high molecular weight natural humified soil extract, a proprietary oxygen catalyst and a tiny amount of surfactant to break the surface tension, enhancing the speed of microbial remediation. Many of the special strains in this formula ferment most sugars and tolerate more acid conditions and higher salt than most other Bacillus.. ALKEN CLEAR-FLO 7139 is biodegradable and harmless to humans, pets, livestock, and wildlife, when used as directed.

For additional information on humic substances, see Properties of Humic Substances at:

  • Inoculates contaminated materials with petroleum degrading and hydrogen sulfide oxidizing bacteria
  • Inoculates contaminated materials with petroleum degrading bacteria.
  • Shortens clean-up times for oil spills.
  • Contains essential microbial nutrients and oxygen catalysts.
  • Contains slow release, polyphenolic aromatic biopolymer with cation. exchange capacity 350 - 900 meg/100 grams, to promote improved settling at low cost
  • Buffering agent for high-salt stress and seven strains tolerate 7% or higher salt levels.
  • Scavenges free radicals.
  • Concentrate is stable and has a long shelf-life.


Use Industrial/Municipal dosage chart, substituting 1 gallon for each lb. of dry product prescribed on the dosage chart Alternatively, bench test for specific dosage for a given wastewater. For use on oil slicks in a marina, both on the dock and in the water, dilute one part CF 7139 with 15 parts water and spray onto the surface of the oil.


ALKEN CLEAR-FLO® 7139 is packaged in single 5 gallon plastic pails with spout for pouring. Store in a cool, dry place. Avoid inhalation of mist and wash hands with warm soapy water after handling.
