Biological wastewater treatment

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.

White Paper: Nitrification in Wastewater Treatment Plants (English)

Nitrogen removal from wastewater is possible in many different types of biological wastewater treatment plants. From activated sludge systems, biorotors, MBBR systems, and trickling filters, they all operate under more or less the same operating conditions. Read this white paper for more information about these conditions.

Case study on the restoration of nitrification in a wastewater treatment plant (English)

This case study describes how bioaugmentation restores nitrification in a wastewater treatment plant after an extremely cold spell. This wastewater treatment plant receives not only wastewater from a port city but also leachate from the landfill and ammonium-rich supernatant from the sludge digester.
