Biological wastewater treatment<\/p>\n<\/div>
The most commonly used wastewater treatment process is the activated sludge process. The performance of these systems depends on the composition and behavior of the microbial biomass. These systems occasionally encounter operational problems due to changes in influent composition, fluctuating quantities, and pH and temperature fluctuations. QM products can help stabilize biological treatment, maintaining consistent effluent quality. Read about some successful applications on this page.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
