Siemens Water Technologies magnetite ballasted CoMag System, which is already helping municipalities to increase water and wastewater treatment plant clarification performance in confined footprints, is now available for industrial water and wastewater treatment applications.
The CoMag System (pictured) uses magnetite to ballast conventional chemical floc for enhanced settling rates and increased performance of wastewater and water treatment operations, the company says. It also reduces capital and life-cycle costs, according to Siemens.
The CoMag System removes contaminants by reducing total suspended solids (TSS), total phosphorus (TP), turbidity, color, pathogens and metals far below conventional treatment, the company says. The system enables designers and plant operators with space constraints to economically expand treatment capacity and limit the footprint of planned facilities.
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, Mass., wastewater treatment plant using a combination of Siemens BioMag and CoMag Systems.
The costs of retrofits and upgrades to existing systems pose a challenge to industrial water treatment operators, making design and implementation costs of water and wastewater treatment systems a key differentiating advantage in the market, says Ankur Jajoo, Frost & Sullivan energy and environment industry analyst.
Jajoo says the CoMag System is “financially attractive to implement and minimizes large-scale design changes.” The product can help industrial operators cut operational costs while improving contaminant removal, he says.
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, Siemens says. 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, according to the company.
