HEI's
plasma treatment of water and/or water solutions can be used
for obtaining highly active micro- |
| cluster
liquids like antibacterial solutions etc. The apparatus for
plasma treatment includes at least one plasma reactor, which
contains coaxial cylindrical and perforated electrodes, a quartz
tube, a grounded cylindrical body, and a diaphragm installed
between the body and the quartz tube. |
| |
The
raw solution is supplied into the reactor between the quartz
tube and the grounded body. Radio- |
| frequency
(RF) pulsed voltage is supplied to the coaxial cylindrical and
perforated electrodes by an RF pulse generator. The quartz tube
contains a mixture of plasma gases: Ar, He, Ne, and Kr under
the vacuum. The RF plasma reactor is biased by Direct Current
(DC) voltage. The treated solution flows out through the product
line. Gases created during the treatment process are discharged
through the by-product line. |
| |
Particular
characteristics of the RF pulsed signal including peak pulse
voltage, duty cycle, and pulse |
| repetition
rate have been selected such that the size of clusters, the
pH, and the Oxidation-Reduction Potential (ORP) of the product
are optimized. |
| |
Clusters
contained in tap water are destroyed and water becomes very
active. Number of molecules |
|
in the cluster is decreasing from 10-24 to 1-3. Water activity
is proportional to the number of clusters (see Figure 1). |

| HEI's
plasma treatment for water makes water much more active and
able to go through membranes or pores and fight most types of
bacteria. The plasma system is a reliable and environmentally
safe alternative to chemical-based water treatment technologies. |
