Sludge Conditioning to Aid Sludge De-Watering

Most sludge de-watering applications will benefit from sludge conditioning ahead of the thickening or de-watering device. Coagulants and flocculants, polymers, are widely used in many industries to remove water from wet solids (sludge). Note that flocculants alone are often all that is required to improve sludge de-watering. This process is known as sludge conditioning. Water release from sludge is affected by electrostatic forces of attraction and repulsion that control floc formation and size. Floc size and uniformity controls the flow of water through the sludge under gravity (de-watering boxes), or under pressure (belt presses and plate and frame filter presses). ... » Read More
