- Secured uniformity in efficiency of the device by application of a feeder that can adjust the thickness of the supplied cake

- A number of upper reduction modules can adjust the pressure and voltage respectively according to the sludge. 
 Risk of electric shock can be eliminated by perfect insulation and sensing of the leaked electric current.

- Maintain uniform dehydration efficiency by cleaning the electrode plate regularly by using the automatic cleaning device.

- Lower electrode shall move downward during maintenance and electrode plate cleaning.
