The innovative BioMag®​ system​ uses magnetite -- fully inert iron ore particles -- to enhance the clarification process. The system uses the world's fastest proven ballasted clarification technology for biological floc -- allowing capacity expansion and performance improvement with minimal plant modifications at the lowest cost possible. In fact, it consistently achieves a sludge volume index (SVI) of less than 50!

The BioMag system is primarily used for wastewater intensification in activated sludge systems. It allows operators to control the sludge blanket, achieve high contaminant removal, and manage variable loads and flows.

Wastewater treatment facilities upgrade with the BioMag system to reduce the cost of complying with stringent new nutrient removal limits. 

• Easy to incorporate in most activated sludge treatment systems and in turn intensifies the wastewater process.
• BioMag® system equipment is located in the sidestream location (WAS stream) without impacting main liquid stream in Water Reclamation Facilities. 
• Magnetite is readily available (iron ore commodity), fully inert, non-abrasive (particle size is 10-15 microns), and magnetically retrievable with a proprietary magnetic recovery drum.
• Easy/simple to operate and has successfully been applied across many industries.
• Evoqua has several mobile units that can help in challenging staged constructions, or temporarily alleviate issues related to poor settling sludge
• Fully automated

• Simplicity and reliability, ballasting biological floc with magnetite dramatically intensifies secondary settling rates eliminating bottlenecks to process greater loads, flows or both.
• Rapid and reliable settling enables a 2 – 3x increase in MLSS concentrations without the risk of upset, and an equivalent increase in treatment capacity — all within existing bioreactors and clarifiers.
• Increased capacity and superior solids removal enable existing activated sludge systems to free up reactor capacity for multi-stage treatment processes and provides enhanced nutrient removal, TN to ≤ 3.0 mg/L and TP to ≤ 0.2 mg/L without tertiary filters.
• The BioMag System continuously recovers and reuses up to 95% of the injected magnetite offering a cost-effective, sustainable process.
• Sludge biology is not affected by the inert chemistry.
