ABSTRACT:
A process using an electrical signal for electrokinetic floatation of solids and semi-solids in paint sludge water includes collecting the paint sludge water into a tank. The process further includes generating the electrical signal from a bottom of the tank to separate the solids and semi-solids from the water in the paint sludge water to induce electrokinetic floatation of the solids and semi-solids to a top surface in the tank. After separating the solids and semi-solids from the water, the process includes removing the solids and semi-solids from the tank.
