Formula 45F: Advanced Bacteria Supplement for Effective Filamentous Control

  • Formula 45F

  • Filamentous organisms can pose significant challenges in aerobic wastewater treatment systems, leading to sludge bulking, foaming, reduced treatment efficiency, and increased sludge volume index (SVI).

    Formula 45F is a specialized blend of microorganisms designed to minimize the buildup of filamentous organisms in these systems. It promotes the formation of dense, well-settling floc with exceptional dewatering properties. In cases of severe filamentous bulking, Formula 45F can be used alongside chemical treatments for enhanced results.

Using Formula 45F

Dosing Schedule:

Flow Rate Initial Dosage Maintenance
Up to 1,000 GPD ½ lb. per day for 3 days ½ lb. per week
Up to 5,000 GPD ½ lb. per day for 3 days 1 lb. per week
Up to 20,000 GPD 5 lbs.* 1 ½ lb. per week
Up to 50,000 GPD 8 lbs.* 2 lb. per week
Up to 250,000 GPD 15 lbs.* ¼ lb. per day
Up to 500,000 GPD 25 lbs.* ½ lb. per day
Up to 1 MGD 50 lbs.* 1 lb. per day
Up to 5 MGD 50 lbs. per MGD* 1 lb. per MGD per day
Up to 12 MGD 50 lbs. per MGD* ¾ lb. per MGD per day
Up to 100 MGD 30 lbs. per MGD* ½ lb. per MGD per day

* Spread this initial dosage out over the course of 10 days.

* Add as regularly as possible. If a day is missed, add that day’s product with the next dosage.

Dosage rate will vary with flow rates, retention times, and system variations.

Do not add to the treatment system at a location where toxic or adverse pH, dissolved oxygen, or temperature conditions exist at peak levels.

For optimal results the wastewater and treatment system should meet the following conditions:

Optimum Minimum
Influent pH 7.0 5.0
Dissolved Oxygen (ppm) 2.0+ 1.0+
C/N/P Ratio 100/10/1 100/5/1
Temperature (°C) 30° (86°F) 10° (50°F)
Toxic Metals (ppm) 0 0

Storage and Handling

Storage: Store in a cool, dry place

Handling: Wash hands thoroughly with warm, soapy water after handling
