As a follower of this blog will be aware, the majority of surface water treatment systems in the Dallas-Fort Worth Metroplex and North Texas have added ozone to their treatment process. Currently, more than 130,000 lbs/day of ozone capacity is installed to treat up to 2.5 billion gallons per day (BGD) of drinking water in North Texas with the City of Dallas accounting for 40% of this capacity.
These utilities experience many of the multiple benefits ozone brings to water treatment including seasonal taste and odor control, reduced DBP levels, enhanced filtration with lower turbidity, chemical dosing and solids handling in addition to superior disinfection.
Mazzei® mass transfer systems have played an important role in putting Ozone to Work© in new, expanded or updated North Texas water treatment plants in the last 7 years. The 5 most recent ozone installation chose patented Mazzei venture injectors, basin mixing nozzle manifolds, pipeline flash reactors or full GDT transfer and degassing systems to add up to 52,000 lbs/day of ozone to nearly 900 MGD of drinking water. Benefits of the Mazzei systems included mass transfer efficiencies ranging from 90 to 98%, small footprint, large turn down ratio, easy installation and low maintenance.
Spartan employs Mazzei products in its ozone water treatment installations and considers Mazzei to be a important partner/supplier.
