ALKEN® BIO-NUTRIENT 3L is a rapidly absorbed liquid nutrient supplement designed to enhance bacterial metabolism of toxic chemicals in industrial waste by the Alken Clear-Flo® 4003, 4003, 4004, 4006, 4007, 7000 series and Alken Enz-Odor® 6, 8 & 14. This formula is required for degrading in industrial wastewater, known to contain high levels of organic carbon along with insufficient levels of soluble nitrogen and phosphorus. ALKEN® BIO-NUTRIENT 3 contains a blend of ammonium chloride and diammonium phosphate, providing an ideal ratio of nitrogen to phosphorous of 5 to 1. While the waste-water is being analyzed for basic nutrients (ammonia, nitrite, nitrate, phosphate, TOC, COD, BOD, dissolved oxygen, etc.), additional tests should be performed for pH, alkalinity, unusual suspected pollutants, micro-nutrients and minerals. ALKEN® BIO-NUTRIENT 8 or ALKEN® 896 BioStimulant can be used to supplement micro-nutrient deficiencies, while triggering enhanced germination rates and overall improved performance of Alken-Murray microbial cultures, even if no deficiency exists. A pH controller can be set up to attach two Tygon tubes from reservoirs to a two-reservoir metering pump. With this setup, one reservoir delivers acid and the other one delivers base. Eliminating wildly fluctuating pH reduces stress on the bacteria so that they more rapidly deliver desired results.



 Appearance:  Off-white liquid

  • Promotes a uniform biomass regardless of system load.
  • Increases metabolic rate of Alken Clear-Flo® 4003,4004, 4006, 4007, Alken Clear-Flo® 7000 series and Alken Enz-Odor® 6,8 &14.
  • Effective over a wide temperature (35 deg.F to 180 deg.F) and pH range (6.0 to 9.5)


Apply prescribed dose directly to target wastewater system. Alken ® Bio-Nutrient 3 (Liquid) - use where three times as much nitrogen is needed as phosphorus

 Dosage Chart

If wastestream is extremely unbalanced and retention time is very short, you may wish to grow the bacteria for 24 hours, to increase the count by one log of growth, by combining wastewater, nutrients and bacterial inoculation in a temperature controlled (approx.70 F or 21 deg. C) tank or drum. A pH adjuster may be added to the waste stream, if necessary, to obtain the preferred pH range of 6.8 to 7.4.


ALKEN BIO-NUTRIENT 3L is packaged in 55 gallon plastic drums. Store in a cool dry place. Avoid inhalation of aerosol mist and wash hands with warm soapy water after handling.
