ALKEN CLEAR-FLO® 7004 is a concentrated dry blend of selected naturally occurring bacteria, having the exceptional capability to degrade wastewater containing detergents (nonionic and anionic surfactants), phenols, biosurfactants and emulsifiers. Accordingly, ALKEN CLEAR-FLO® 7004 finds special application in treating wastewater emanating from the textile and textile chemical industries where processes such as chemical formulation, wool scouring, knitting, weaving, desizing, dyeing, finishing, bleaching, printing and coating generate wastes of the type in question. This formula also degrades tannins from leather manufacturing.



 Bacteria Count  5 billion CFU per gram
 Appearance  Free-flowing, tan-brown powder
 Odor  Yeast-like
 pH  Neutral


  • Degrades anionic and nonionic surfactants, including nonylphenol ethoxylates, linear and branched alcohol ethoxylates, linear alkyl sulfonate, alkylbenzene sulfonate, sodium xylene sulfonate and soaps (alkali salts of fatty acids).
  • Degrades surfactant components aromatics, phenolics and fatty acids.
  • Effectively reduces foaming and eliminates the need for chemical anti-foams.
  • Reduces aeration requirements.
  • Improves efficiency of BOD and COD reduction.
  • Cultures perform best with aeration, but some strains can function without.
  • Effective over temperature range 25 to 42 degrees C (77 to 107 degrees F)
  • Effective over a wide pH range (6.0 to 8.5).
  • Non-toxic, non-corrosive, completely safe to handle and store.



 Industrial/Municipal dosage charts
for general application rates. Your Alken-Murray service representative will prescribe both the initial application and the maintenance doses taking into consideration such factors as the total daily influent and effluent, BOD/COD loadings, suspended solids and levels of pesticides or other contaminants. Be aware that a heavy rainfall may bring significant contamination with its runoff, and a one-time dosage equal to the initial application may be needed to restore control. Mechanical aeration may be needed where natural aeration is deficient.


Although product may be applied dry, either loose or in soluble packets, for optimum bacterial performance, we recommend that you hydrate ALKEN CLEAR-FLO® 7004 before application. Thoroughly mix each pound of dry product with two gallons of warm (approx.70 F) water without chlorine. Allow the mixture to hydrate for two hours, stirring vigorously every half hour. After final settling, carefully pour off the top liquid layer for use, squeeze all liquid from the bran that has settled into the liquid and either dispose of the remaining bran, or toss into the system. Avoid use of algaecides, herbicides, and antibiotics when using ALKEN CLEAR-FLO®.


ALKEN CLEAR-FLO® 7004 is packaged in 25, 50 and 500 lb. containers. Store in a cool dry place. Avoid excessive inhalation as well as contact with eyes, skin and open wounds. Wash hands with warm, soapy water after handling.
