 ALKEN ENZ-ODOR® 10

Material Safety Data Sheet 

Hydrogen Sulfide Treatise

 



HYDROGEN SULFIDE TREATMENT FOR ANAEROBIC DIGESTERS


DESCRIPTION:

ALKEN ENZ-ODOR® 10 contains chemical bio-stimulants and electron acceptors that increase the metabolic rate of the powerful blend of six specially selected non-pathogenic strains of Bacillus for nearly immediate relief from hydrogen sulfide odors and digestion of food fats and grease into the fatty acids required by methanogens for good production of methane. Methanogens can be killed by contact with either air or hydrogen sulfide, so it is vitally important to oxidize hydrogen sulfide without producing free oxygen in the system. We have included two unique strains of Bacillus from a new species that oxidizes sulfide and a really strong new grease degrading Bacillus. Other strains in the formula enhance metabolism of general wastes, reducing overall BOD and COD in the system.

 

CHARACTERISTICS: 

 Bacteria Count:

 150 MILLION CFU/ml

(568 billion CFU/gal)

 Appearance:  Translucent ivory color liquid
 pH:  7.0 - 8.8
 Odor:  None to slight
 Specific Gravity: 1.21 +/- 0.05 at 15 degrees C
Shelf life:  Indefinite

FEATURES AND BENEFITS:

  • Protects from corrosion by eliminating formation of sulfuric acid during sulfide oxidation.
  • Assists oxidization of chlorite in the system.
  • Tested and certified negative for Salmonella, Shigella & E.Coli .
  • Contains NO chemical surfactants or solvents.
  • 100% gram-positive, spore-form bacteria.
  • pH range: 5.0 to 8.0, with optimum pH range of 6.0 to 7.5
  • Temperature range: 42 deg. F to 100 deg. F (6 deg. to 37.7 deg. C)

DOSAGE:

ALKEN ENZ-ODOR® 10 should be fed directly to system, using a chemical metering pump, withdrawing directly from pail, drum or tote in which product is shipped. For best results, divide calculated daily dosage into 96 small doses, dispensed every 15 minutes, for uniform treatment of all wastewater flowing through system.

Initial Application: 19.2 Liters of Alken Enz-Odor 9 for each 1 Kg of sulfide present (or 2.3 gallons per 1 pound sulfide in wastewater).

Maintenance for Flowing System: Apply daily 4.2 Liters per 1 Kg of sulfide present in daily volume, following initial application, described above.


APPLICATION:

For best results, link product dosage-metering pumps to station pumps, so that wastewater is continuously treated as it enters the system. Since hydrogen sulfide generation is inversely related to flow rate, dosage should be increased during low flows and reduced during peak flows. When applying to anaerobic digesters, routinely monitor fatty acid/alkalinity ratio and compare with historical values to guard against increased rates of acid formation. pH levels should be monitored in anaerobic lagoons and equalization basins and alkalinity adjusted if necessary to keep the pH from dropping below 5.0, which would inhibit microbial performance. ALKEN ENZ-ODOR® 10 can be used in conjunction with ALKEN CLEAR-FLO ® 7008 or ALKEN CLEAR-FLO® 4007 , whichever product is prescribed for specific wastewater, by an authorized Alken-Murray distributor or Alken-Murray technical support.


PACKAGING AND HANDLING:

ALKEN ENZ-ODOR® 10 is packaged in 5 and 55 gallon plastic drums and 250 gallon totes. Store above -15 deg. C or 5 deg. F. Bacterial spores are dense and can settle during shipment and storage. Formula should be stirred or otherwise mixed thoroughly prior to use and once or twice a week during use. Store in a cool dry place. Avoid inhalation of mist and wash hands with warm soapy water after handling. Avoid eye contact.
