Low temperatures in wastewater can pose problems including reduced biological activity and increased solidifying of fats, oils, and grease.
Formula 99C is a unique blend of psychrophilic (cold loving) bacteria that thrive in colder water temperatures and effectively produce enzymes and metabolize BOD. It ensures consistent treatment performance even when the wastewater temperature is as low as 36ºF.
