MB 1138 BP contains a blend of psychrophilic (cold-loving) microorganisms that remain active down to 2°C (36°F). The strains have a wide range of organic degradation abilities and are therefore particularly well suited to municipal plants that receive waste streams from industrial facilities.
Temperature drops impact the bacterial metabolism and reproduction of microorganisms. Reaction rates typically decrease by a half for each 10 °C (50 °F) drop. This decrease in reaction rate is often first seen as a decrease in oxygen uptake rate (OUR) activity or as a decline in COD removal. It can take months for the microbial community to adapt to low-temperature conditions, causing plant operating problems.
MB 1138 BP contains beneficial microorganisms proven to tolerate cold-temperature wastewater applications. By building microbial communities with MB 1138 BP just prior to seasonal changes, wastewater operators ensure a safe and fast transition for winter operation. Many wastewater facilities find it difficult to lower their F/M ratio in cold temperatures as many microorganisms tend to spend their energy on stress-induced cellular maintenance instead of reproduction. Augmenting with MB 1138 BP removes this challenge as the microorganisms’ reproduction is not restricted.
