Název v původním jazyce
A sub-atmospheric pressure discharge generated in hydrodynamic cavitation for water treatment
Popis výsledku v původním jazyce
We present a recently developed plasma source that uses a synergistic effect of hydrodynamical cavitation and electrical discharge in cavitating environment, called “CaviPlasma”. This plasma device breaks the limits of existing plasma generators offering the industrial-scale flow rate of 1-15 m3/h (laboratory devices) introducing peroxide-based chemistry into treated water, thus keeping the pH practically unchanged (within 0.5 pH difference margin). We have achieved the peroxide concentration higher than 10 mg/l per one water passage through the CaviPlasma and peroxide yield of G(H2O2) = 9.5 g/kWh, which ranks CaviPlasma to high efficiency plasma sources. The effects of CaviPlasma water treatment were proven on the study of the successful remediation of cyanobacteria and algae from water, inactivation of pathogens collected from hospital environment surfaces or inactivation of the main rainbow trout pathogenic bacteria.
