Abstract
The purpose of this study is to
investigate the effects of processing
conditions on properties of EOW. This study
adopted a duplicated three-factor central
composite design to study the effects of rawwater
flow rate, salt concentration and water
temperature on pH, oxidation- reduction
potential (ORP), total chlorine, conductivity,
dissolved oxygen (DO), chloride ion and
sodium ion concentrations of EOW.
Furthermore, a study on the efficiency of
EOW generator and a study on storage
properties of the EOW were also conducted.
Results indicated that increasing water
flow rate decreased total chlorine
concentration and ORP of the EOW.
Increasing salt concentration increased total
chlorine concentration and electrical
conductivity of the EOW. Results also
indicated that electrolysis efficiency of the
electrolysis cell varied in the range of 47 %
to 66 %. Separation efficiency of the cation
ion-exchange membrane varied in the range
of 33 % to 59 %. Both efficiency rates were
significantly reduced by increases in water
flow rate and/or salt concentration in the feed
solution. Results also indicated that total
residual chlorine and DO decreased 24% and
21%, respectively, in the 21-day closed
storage and decreased 81% and 47%,
respectively, in the 14-day semi-open
storage.
