Title Electrochemical Process for
Decreasing of Pesticide and Cyanide Contamination The problem the inventor(s) wanted to solve The mostly of toxic
contaminant has not degradation by biological method. The classical chemical
processes usually have heavy environmental effects. Description. We have developed an
electrochemical method for decontamination of toxic materials by electro-Fenton
reactions. This is the total mineralisation of
organic compounds. The reaction agents generation
are “in-situ” process in water or waste water system. This is a good method
for controlling the decontamination and decreasing of chemical hazards. Presentation. The objects of
the invention are a reaction parameter system and decontamination process,
witch available for top water treatment and wastewater decontamination if
these has pesticide and cyanide contaminant. With the available electrode
materials and ion selective membrane the hydroxide radicals and Iron(II)-ions “in-site” take its origin in the
electrochemical cell. The role of Iron(II)-ions is
the increasing of reaction velocity. Optimaizing of
mineralisation’s efficiency and reaction time were
by the cell volume and electrode potentials. With this process the treated
top water and waste water chemical parameters (COD, TOC) ready for EU
standard. The advantages of system we
can see in the I. Table, with the different oxidation species. The hydroxyl
radical has the highest relative oxidation power. With the optimisation of
electrochemical system, we can obtain a very low COD and TOC level and
guarantee the minimalized bacteria number. With
this process in the treated water we have not chlorinated toxic compound. Application Water plant, waste water
treatment. Advantages ·
does not increasing of volume of waste water ·
have not using high temperature ·
toxicity reduction ·
do not using chemicals Stage of development. Ready for market in
laboratory scale, further optimalization of the
size and electrochemical parameters for the waste treatment Documentation available: Test reports |
