Why use Formula 45F?

Aerobic wastewater treatment systems can experience issues such as bulking sludge, foaming, reduced treatment efficiency, and elevated sludge volume index (SVI) due to the presence of various filamentous organisms.

Formula 45F is a specially formulated blend of microorganisms designed to slow the accumulation of these organisms. It promotes the formation of a dense, well-settling floc with excellent dewatering properties. For plants experiencing severe filamentous bulking, Formula 45F can be used in conjunction with chlorination, hypochlorite, or peroxide treatment programs.

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
