The first EKG (E-board) in China:

The first field trial using E-board in China:
Zhuang, Y.F., Huang,
Y., Liu, F., Zou, W., Li, Z., 2014. Case study on hydraulic reclaimed sludge
consolidation using electrokinetic geosynthetics. In: 10th International Conference
on Geosynthetics. DGGT, Berlin, Germany.
After the field trial, it was found that power requirement, instead of energy consumption, is the biggest challenge for field application using electro-osmosis. And I believe this is the case for most applications using electrokinetic technique in Geo.

Challenges of electro-osmotic consolidation in large scale application. In:
Conference of Geosynthetics 2015. IFAI, Portland, Oregon, USA, pp. 447–449.
Therefore, I have been focusing on Smart DC Power Source and looking for a way to reduce both power requirement and energy consumption. Roll Polling Program seems to be a solution. It reduces the requirement of current intensity to 1/3; it also decreases the energy consumption to less than 1 kW⋅h/m3. Following contents are direct quote from the publication:
