New Way for California Water Operators to Lower Ozone Generation Costs

BRIDGEWATER, N.J., Nov. 9, 2017 /PRNewswire/ -- A new oxygen recovery system that can dramatically reduce oxygen (O(2)) consumption during ozone production for water treatment will be featured by Linde LLC at the Association of California Water Agencies (ACWA) conference, Nov. 28-Dec. 1, in Anaheim, California, booth 110.

"The patented OZORA(TM) system can help the many California water treatment operators that depend on ozonation maximize their investment -- and it can positively shift the economics for those operators who are not using ozonation," said Peter Studer, Program Manager, Linde LLC, who will present an overview at a conference session, Nov. 29(th) at 10 a.m.

About 90% of the O(2) used by an ozone generator is not converted to ozone (O(3)) and remains unused at a high cost to the water treatment operator. Linde leveraged its deep knowledge of adsorption processes to create the OZORA oxygen recovery system which efficiently separates O(3) and recycles the unused O(2) back to the O(3) generator, reducing O(2) consumption by up to 60%.

The OZORA system was jointly tested and validated with SUEZ, a leading manufacturer of ozone generators and a prominent player in the water treatment industry. It can be sized to match new O(3) generation units, or engineered to retrofit existing water treatment operations.

Also at ACWA, Linde will present two other innovations for water treatment: SOLVOX(®) mobile for oxygenation and SOLVOCARB(®) venturi for efficiently controlling the pH of water with high total dissolved solids.

    --  SOLVOX mobile is a new oxygenation technology specifically developed to
        help wastewater treatment plants cope with peak loads and downtime
        during aeration equipment maintenance. Its free-floating design allows
        for a simple and straightforward installation, even in
        challenging-shaped basins.
    --  SOLVOCARB venturi provides high rates of carbon dioxide (CO(2)) mass
        transfer coupled with superior uptake efficiency for pH control. This
        technology is easily retrofitted in existing hydraulic systems and
        ensures a consistent performance with low energy loss, while requiring
        low maintenance. Using CO(2 )for alkalinity control avoids the safety
        hazards and overtreatment issues associated with mineral acids.

Linde, a global leader in industrial gases and engineering, also supplies bulk O(2) and nitrogen gases for O(3) production, as well as bulk O(2) and CO(2) for municipal and industrial water and wastewater treatment.
