| Abstract |
Electrophoresis may offer a new technique to repair in service leaking geomembrane liner of municipal solid waste (MSW) impoundment. The method involves introducing a suspended clay particles, which are charged negatively, into the leakage in geomembrane liners by electrokinetic phenomena and formation of clay cake around leakage for prevention of leachate outflows. Therefore, the 3-dimensional leakage simulation experiments are conducted to evaluate the field applicability of sealing leaks of waste impoundment. In addition, the adequateness of optimum influence factors deduced from 1-dimensional experiments is evaluated. After the test, the total size (width, length) of clay cake formation around leak is increased with enlargement of leakage diameter and distance decrease detween anode and cathode. |
