The Science Behind It
Problems such as low food conditions can cause filamentous bulking and a cloudy effluent and operators struggle to keep their bugs alive.
To help plants that have low incoming food we have developed VitaStim Low F:M a bioaugmentation product this uses bacteria that culture and floc well in low food conditions.
In addition, it contains micronutrients that are steroids for the existing bacterial cultures. VitaStim Low F:M stimulates the development of a robust biomass of floc forming bacteria that provide excellent nutrient uptake, better settling, less filamentous and a clean effluent
This oxidation ditch has low F:M and uses our VitaStim Low F:M to reduce filaments, improve settling and clarify the effluent.
VitaStim Low F:M – Appplications
- Wastewater Plants
- Industrial Plants
- Chemical Plants
- Creates a healthier biomass
- Prevents filaments
- Improves settling
- Improves nutrient removal
Low F:M Ratio
- 2 lbs per 500,000 gallon flow rate per day
- 2 lbs per 500,000 gallon flow rate per day (As complement to BugJuice)
- When used with AQUABACxt to rebuild ML 2 lbs per 500,000 gallon flow rate per day
Incoming Flow: 0.5 MGD
Incoming BOD: 100 ppm
Gallons in aeration and clarifier: 1.5 MG (expressed in million gallons)
0.5 MGD x 100 ppm = .013 is your F:M ratio
1.5 MG x 2500
Conventional activated sludge calls for a 0.1 to 0.5 ration, but the ratio can be 0.2 to 0.1 in extended air plants. The bottom line is many municipal plants have a number that is too low and our VitaStim Low F:M will really help them. Our calculation is simplified because ultimately it’s not the accuracy of this number it’s how your individual plant bacteria respond this this ratio.
