Electro-kinetic dewatering of oily sludges
Journal of Hazardous Materials, 2005An oily sludge from a rendering facility was treated using electro-kinetic (EK) techniques employing two different experimental designs. The bench scale used vertical electrodes under different operational conditions, i.e. varied electrode spacing at 4, 6 and 8 cm with electric potential of 10, 20 and 30 V, respectively.

Dewatering of Activated Sludge
1981Activated sludge is often conditioned with the aid of polyelectrolyte to a highly flocculent state to facilitate dewatering by filtration. Activated sludges in this condition have excellent drainage characteristics when subject to low solids stress, as in gravity drainage at low filter loadings. When subject to large hydraulic gradients, however, as in
