Fats, oils, and grease (FOG) can create significant issues in wastewater treatment plants and food processing facilities – from clogs and blockages to unpleasant odors and reduced treatment efficiency.
Formula 21HG is designed to reduce the accumulation of FOG and other organic deposits. It promotes the growth of a specialized biomass capable of breaking down tough wastes such as meat, cooking oil, margarine, butter, shortening, and dairy products.
| 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.
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 |
