  6. Expansion And Upgrade Of WWTP Ozone Disinfection System Reduces Energy Cost By 69%
    4/27/2017

    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.

  7. How To Know It’s Time To Replace Your RO Membrane
    9/5/2017

    Reverse osmosis, or RO, is one of the finest technologies to purify water containing high total dissolved solids (TDS) levels of more than 500 ppm. Reverse osmosis plant exporters explain the technology as a separation technology where dissolved and invisible impurities in water are separated with the help of semi-permeable membrane or RO membrane that works under high pressure.

  8. Examining Options To Reduce Lead In Drinking Water
    10/26/2016

    National Lead Poisoning Prevention Week marks a time when EPA and our federal partners promote education and awareness activities that focus on lead and how to prevent its negative health effects. This year, we focus on the theme, “Lead-Free Kids for a Healthy Future.” It’s through our joint efforts that we have been able to make significant strides in reducing exposure to lead over the past several decades.
