Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%
9/10/2018
The financial cost to maintain their ozone equipment, and increasing scarcity of replacement parts for their ozone generator, motivated a utility in Springfield, MO, to upgrade their ozone system. Read the full case study to learn how the plant assessed the energy cost of a sidestream ozone injection system compared to that of a turbine mixing design and showed that the Mazzei retrofit design reduced the energy cost of ozone contacting by an average of 69.2% under all plant flow conditions.

Robust Encore® Pumps Replace Peristaltic Hose Pumps To Maintain Consistent pH For Finished Drinking Water
8/22/2018
Upper Deerfield Township, NJ relies on groundwater from four wells measuring 120 to 160 feet deep. The water is treated at two treatment plants with a capacity of 2.2 MGD and then pumped out to the distribution system with approximately 750,000 gallons of storage. Since the deep groundwater is hard, operators add lime to the finished water to raise the pH to reduce hardness.
