Cold temperatures can slow biological activity and hinder wastewater treatment performance. Formula 99C is an advanced blend of psychrophilic bacteria designed to thrive in wastewater systems with temperatures as low as 36°F. This powerful microbial supplement enhances biological treatment, reduces solids buildup, and optimizes cold-weather system performance.

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 | 30° (86°F) | 10° (50°F) |
| Toxic Metals (ppm) | 0 | 0 |
