Siemens Water Technologies magnetite ballasted CoMag^® System, a proven
solution for municipalities to increase water and wastewater treatment plant
clarification performance in confined footprints, is now available for
industrial water and wastewater treatment applications.

Simple and reliable, the CoMag System uses magnetite to ballast conventional
chemical floc for enhanced settling rates and increased performance of
wastewater and water treatment operations while substantially reducing capital
and life-cycle costs. The CoMag System provides superior contaminant removal
by reducing total suspended solids (TSS), total phosphorus (TP), turbidity,
color, pathogens and metals far below conventional treatment. The system
enables designers and plant operators who have space constraints to
economically expand treatment capacity and limit the footprint of planned

The American Council of Engineering Companies (ACEC) of Massachusetts recently
awarded Tighe & Bond its prestigious Gold Award for its work at the Town of
Sturbridge, MA wastewater treatment plant using an innovative combination of
Siemens BioMag^® and CoMag ^ Systems.

“Industrial water treatment operators are challenged by the costs of retrofits
and upgrades for existing systems. The design and implementation costs of
water and wastewater treatment systems have become a key differentiating
advantage in the market. The CoMag is a system which is financially attractive
to implement and minimizes large scale design changes,” said Ankur Jajoo,
Frost & Sullivan energy and environment industry analyst. “Magnetite ballasted
technology is a proven municipal solution that enhances clarification
performance without space or cost penalties. The design features enable the
CoMag to be applied at any stage of treatment and is now a viable alternative
for industrial operators to reduce operational expenditure yet enhance
contaminant removal.”

“The CoMag System offers distinct advantages for industrial plant operators
who need to increase water and wastewater treatment capacity and performance,”
said Kevin Warheit, Siemens Water Technologies global product manager. “With a
much smaller footprint, higher performance and lower capital costs, the CoMag
System can be easily integrated into existing plant infrastructure and
configured to meet a wide range of plant capacity requirements.”

The CoMag System for industrial applications includes TSS and heavy metals
removal for recycle-reuse, reverse osmosis (RO) pretreatment and other uses.
The system incorporates a modified compact high rate Lancy™ Solids Separator
to minimize the amount of solids escaping the unit. In addition to achieving
high rate clarification, the CoMag System employs a sludge recycle function to
increase the system performance and the clarity of its effluent. Approximately
20 percent of the clarifier underflow is recirculated back to the ballast
reaction tank to enhance the chemical process. Up to 99 percent of the
magnetite is recovered and returned to the system.
