摘要:
Dewatering mechanism due to electro-osmosis is fairly different from that of mechanical dewataine which has been used conventionally. and electro-osmotic dewatering has Several advantages compared with the mechanical dewatering and it can be remarkably effective for hardly dewaterable sludges such as very fine Particles and gelatinous materials. In electro-osmotically enhanced dewatering, however, it would be a great problem that the achievement of complete water removal within the sludge could not be possible in principle. Because. when a liauid state in the sludge becomes to be not continuous gradually with proceeding of dewatering, the sludge does not lead electricity and and then electro-osmosis is no longer caused.
