New Ozora oxygen recovery system

Water and waste­water treat­ment oper­a­tors are increas­ing­ly chal­lenged to remove microp­ol­lu­tants from water. Com­pared with con­ven­tion­al waste­water treat­ment process­es, which fail to remove the con­t­a­m­i­nants com­plete­ly, oxi­da­tion with ozone has proved to be one of the most effi­cient meth­ods avail­able. Most indus­tri­al-scale ozone gen­er­a­tors are fed with oxy­gen (O₂) gas. How­ev­er, only a small per­cent­age of the gas is actu­al­ly con­vert­ed into ozone, with around 90% remain­ing unused.
As a expert in adsorp­tion tech­nolo­gies, Linde has devel­oped Ozo­ra to increase the effi­cien­cy poten­tial of the ozone process. Ozo­ra enables up to 60% of the oxy­gen used for ozone gen­er­a­tion to be recov­ered. This trans­lates into sig­nif­i­cant sav­ings – in par­tic­u­lar for ozone flow rates in excess of around 20 kg/h. This tech­nol­o­gy has been joint­ly test­ed and val­i­dat­ed with SUEZ, a man­u­fac­tur­er of ozone gen­er­a­tors and a promi­nent play­er in the water treat­ment industry.
