Abstract
A system and apparatus are disclosed for removing particles from suspension in a liquid, particularly for removing tall oil soap particles from black liquor. The black liquor flows along a fluid flow path (10) which runs between a source of black liquor and a skimming tank. Two electrodes (16, 18) are disposed one downstream of the other within the fluid flow path (10). A power supply (26) applies an electrical potential between the electrodes (16, 18). The downstream electrode (18) is connected to earth ground (36). It has been found that this earth ground connection (36) provides substantial improvements in the quality and quantity of recovered tall oil soap.
