研究了电渗脱水后物料的最终状态。根据我们的理论，如果材料带负电，阳极附近的液体压力变为负值。该负压被力平衡产生的正固体压缩压力抵消，导致材料的局部水分含量降低。这从阳极传播到阴极，直到压力流抵消材料的任何层中的电渗流。本文解释了脱水过程结束时物料的水分分布。它还表明，反转电极的极性的结果在材料的水分含量的进一步减少。
The final states of materials after electro-osmotic dewatering are investigated. Based on our theory, the liquid pressure near the anode becomes negative if the materials are negatively charged. This negative pressure is offset by the positive solid compressive pressure arising from the force balance, resulting in a decrease in the local moisture content of the material. This propagates from the anode to the cathode until the pressure flow cancels out the electro-osmotic flow in any layer of the material. This paper explains the moisture distribution of the material at the end of the dewatering process. It is also shown that reversing the polarity of the electrodes results in a further decrease in the moisture content of the material.
