CoMag® System for Enhanced Primary or Tertiary Treatment

Proven to dramatically increase capacity performance and help to meet tightening regulations.

CoMag® System
The CoMag® System infuses magnetite as a weighing agent into conventional chemical floc, enhancing settling rates and increasing the performance of wastewater and water treatment facilities, while substantially reducing life-cycle costs. It's simple and reliable.

Primarily used to improve primary and/or tertiary treatment, the CoMag System easily integrates with planned or existing facilities, making it easier to solve today’s operational and environmental challenges. 







Applications:

The CoMag System competes effectively with all forms of media and membrane filtration and conventional clarification, and is proven effective for:
  • Primary treatment (Chemically Enhanced Primary Treatment)
  • Tertiary treatment for polishing secondary effluent
  • Stormwater/CSO (combined sewer overflow)
  • Wet weather control
  • Recycle-reuse applications
  • Reverse Osmosis pretreatment
  • Drinking Water
  • Heavy Metals Removal
     

View this short video to see the CoMag® System in action! This quick and efficient tertiary treatment produces effluent quality nearly equivalent to ultrafiltration - at a fraction of the capital expense.   



The enhanced settling capabilities of the CoMag® System has been proven at municipal and industrial facilities to deliver the following results:

 SOR  up to 10x 
 SLR up to 20x 
 Turbidity < 1 NTU 
 TP < 0.05 mg/L 
 TSS < 2.0 mg/L 
 Color 2 Pt-Co Units 
 Fecal Coliform < 200 Col/100 mL 
 Copper <μg/L 
 Aluminum < 80 μg/L
 Arsenic <μg/L
 UV Transmittance > 75%
 Oil and Grease Removal         

Key Benefits of the CoMag System:

  • Superior Contaminant Removal - Efficiently reduce total suspended solids (TSS), total phosphorus (TP), turbidity, color, pathogens and metals far below conventional treatment.
  • Low Costs
    • High-rate, ballasted clarification allows for smaller reaction and solids separation tanks, minimal power consumption and moderate chemical use.
    • The CoMag System continuously recovers and reuses 99+% of the injected magnetite offering a sustainable process for lower OPEX.
  • Improved Productivity - The CoMag System minimizes the risk of upsets and handles a wide range of flows and loads — including peak flow events — with no backwashing, plugging or fouling, no media filters required and almost no effect on contaminant removal performance or operational stability.
  • Ultraviolet Enabling - The high transmissivity of the CoMag System effluent reduces energy and operating costs of final purification.
