 How Bacteria Help Drains, Grease Traps & Septic Systems

  Lab Study

  Respirometer study



ALKEN CLEAR-FLO® 4004 is a specially adapted dry blend of five superior grease, oil and fatty acid degrading microorganisms, a powerful starch degrader, two general waste degrading strains, and a unique metabolism-catalyst cold-weather strain, with extra-cellular lipase, a powerful surfactant, that is effective in small quantities, pH buffers, a vigorous biostimulant, and micronutrients. If hydrogen sulfide is a severe problem, ALKEN ENZ-ODOR® 2 or ALKEN ENZ-ODOR® 9 should also be applied. For waste pits, sump pumps, and large hotel grease traps, ALKEN CLEAR-FLO® 4004 will break up pre-existing grease formation. Follow-up treatment and drainline treatment can be continued with ALKEN ENZ-ODOR® 2, for optimal results.



 Bacteria count

  • Maintain lift stations, wet wells, pumps, and float switches free from grease buildup & failure
  • Degrade primary tank skimmings, eliminate grease problems down-line
  • Degrades glycerol in the drains from X-ray machines
  • Cultures grow in either the presence or absence of oxygen.
  • Rapid degradation of grease, fats and oils.
  • Non-toxic, non-corrosive, safe to handle and store.
  • Effective over a wide temperature range (40 deg.F to 140 deg.F).
  • Effective over a wide pH range (5.5 to 9.0).



To optimize the action of the bacteria, we recommend pre-hydrating for 1 to 2 hours after adding 2 gallons of water at 70 F to 90 F to each pound of product. Make sure water is free of chlorine. Pour entire product, including bran into system. Alternatively, dry powder may be applied directly to the system, either loose or in soluble packets. Avoid use of algaecides, herbicides, and antibiotics when using ALKEN CLEAR-FLO®.To prevent severe grease buildup, treat kitchen drain-lines with liquid ALKEN CLEAR-FLO® 4100, applied by automatic pump.

For large lift stations and grease traps: UseIndustrial/Municipal dosage charts for CF 7000 line.

TREATMENT CHART for smaller applications: 

For initial dose & problem systems: double the suggested feed rate for the first two weeks or until control is achieved.


 Maintenance Feed rate

 Kitchen drain  1 teaspoon per inch diameter of drain  Weekly
 Laundry drain  1 tablespoon per inch diameter of drain  Monthly
 Grease trap  100 - 110 grams in drain close to trap for traps 500 to 1000 gallons in size.  Twice monthly
 Metering pump application  17 grams to 2 oz. (prehydrated w. 1/2 gallon of water)  Daily



ALKEN CLEAR-FLO® 4004 is packaged in 25 lb. pails or 50 lb. fiber drums.. Store in a cool dry place. Avoid contact with eyes, skin and open wounds. Wash hands with warm, soapy water after handling. Read and observe information on MSDS.
