BioMag™ and CoMag™ Systems

BioMag and CoMag Systems from Siemens are next generation wastewater and water solutions that increase the capacity and contaminant removal capabilities of primary, secondary, and tertiary treatment systems.

Maximum capacity, performance & control; minimum footprint & capital

The technologies make the fundamental process of clarification far faster, far more reliable, and far more compact than alternate technologies. They give the operator far more control over effluent values, and a far more robust plant.

Simple, Reliable, Robust
This ground-breaking technology infuses magnetite as a weighting agent into chemical or biological floc, resulting in rapid and enhanced settling and clarification. The technology can be cost effectively applied to both new or existing treatment plants, and greatly reduces footprint and tankage. The process creates much more concentrated suspended solids, and a more dense and stable sludge blanket that makes plants less prone to load and flow variations, and delivers superior nutrient and solids removal. Magnetite is efficiently recovered and recycled.

Performance
The BioMag Ballasted Biological Treatment System enables an existing plant to double or triple its biological treatment capacity and achieve Enhanced Nutrient Removal limits all within existing tanks. BioMag routinely delivers:

TN < 3.0 mg/L
TP < 0.2 mg/L
Turbidity < 1 NTU

The CoMag Particulate Removal System can produce effluent nearly equivalent to ultra-filtration at capital and operating costs competitive with conventional alternatives. It is a perfect technology for tertiary treatment and CSO and storm water management. CoMag routinely delivers:

TP < 0.05 mg/L
TSS < 2.0 mg/L
Turbidity < 1 NTU

Proven
BioMag and CoMag Systems are gaining rapid acceptance by municipalities and engineers.
- BioMag Systems: 3 operating plants; 12 more in design
- CoMag Systems: 8 operating plants; 6 more in design

A Perfect Fit with Siemens
Siemens purchased the technologies through the acquisition of Cambridge Water Technologies in early 2012. Cambridge Water, a leader in high rate water and wastewater treatment, pioneered the commercial application of ballasted floculation in biological systems. These treatment breakthroughs are now backed by the applications experience, technical expertise, and complimentary technology portfolio of Siemens.

Now More than Ever
The increase in treatment requirements, the aging of existing plants, the need for more capacity, and the strain on municipal budgets, all mean that now more than ever is the time for this technology and its promise of breakthrough, cost effective performance.
