Electro-Osmosis Dehydrator
Unlike existing mechanical type pressurized dehydration, the electrical
penetration type uses electrophoresis and Electro-osmosis to separate
sludge moisture and achieve high-efficiency dehydration.
Since sludge is mostly composed of (-) electric charge, sludge cake (water
content of 80% or above) that has gone through 1st dehydration is supplied
between the positive drum and negative caterpillar. By applying direct
voltage, it pushes combined water in the sludge cell to the negative side
for dehydration to achieve high-efficiency dehydration with a water
content of 60wt% or below.
· Special feature of electro-osmosis
dehydrator
Reduce the weight of sludge to 50%.
Increase efficiency dehydration through improved cathode.
Excellent dehydrator ability of the utmost flowing sludge.
Zero failure rate with the reduced parts.
Decrease in water consumption through improved rinse method
