AF-Belt™ Twin Wire Press dewaters sludge mixtures by pressing the sludge between two continuous wires.
The dewatering is arranged in three dewatering sections. The chemically conditioned sludge flows across the gravity and wedge section through the S-curve section, where pressing begins and finally, through the pressure nip rolls, where the sludge is squeezed.
Effective side seals allow a thick sludge cake and clear filtrate.
AF-Belt™ is the most versatile solution to handle mixed sludges, especially those with high or varying ratios of biosludge in the blend. AF-Belt™ is also well-suited for mixed primary and chemical sludges.
