Formula 45F
Filamentous Bacteria Control for Wastewater Treatment

Reduce Sludge Bulking, Improve Settling, and Optimize Treatment Efficiency

Why Use Formula 45F?

Control Filamentous Bacteria in Aerobic Systems

Filamentous bacteria growth in wastewater treatment plants often leads to sludge bulking, foaming, high sludge volume index (SVI), and poor dewatering performance. These operational challenges increase maintenance costs and disrupt treatment efficiency.

Formula 45F is a microbial supplement engineered to suppress filamentous organisms in activated sludge systems. Its specialized bacteria blend promotes dense, well-settling floc formation, improving sludge handling and reducing operational downtime.

Formula 45F is ideal for municipal wastewater treatment plants, industrial facilities, and food processing plants experiencing filament-related issues.

Usage Instructions

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

See label and SDS for safety information.
