Wastewater collection systems often suffer from grease buildup, foul odors, and reduced flow capacity. Formula D-220 is a powerful microbial solution designed to reduce grease buildup and control odor-causing compounds in wastewater systems. Its grease-degrading bacteria form a protective biofilm, enhancing system flow and reducing hydrogen sulfide emissions.
| 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 |
