Low temperatures can have dramatic effects on a microbial community. When this happens it is important to have a microbial community that consists of microbes that are effective at removing organics at lower temperatures.
Many biological wastewater treatment plants experience a reduction in activity at lower operating temperatures. Typically, lower temperatures result in reduced BOD and COD degradation. IFM’s cold weather products exhibit growth and activity below 55o F (13o C) and improve treatment at cold temperatures.
