Effect of flocculation aids on the electric field assisted dewatering of solid liquid systems

Various construction techniques such as tunnel construction and earth drilling result in the production of huge amount muddy water with a high solid-to-liquid ratio. Consequently there is a need for disposing these large quantities of muddy wastewater. Dewatering by conventional belt press filters c...
