The belt filter press is a continuous-feed dewatering device that applies chemical conditioning, gravity draining, and mechanical pressure to dewater sludge. The sludge/slurry is sandwiched between tensioned belts and rolls, by passing those belts through a serpentine of decreasing diameter rolls to remove the moistures and then dispose of the sludge cake. The compressed sludge is reversed several times to be pressed by low?medium and high pressures between two belts, and passively dewatered by squeezing of the rolls.
Purpose:
Liquid/solids separation through pressure filtration.
Features:
Dual filter belt design: Dual filter belt circulation is suitable for a large quantity application.
Low capital and O/M costs: Simple structures, less breakdown and easy to maintain.
Easy operation: Automatic operating while dewatering.
High applicability: Suitable for various slurry waste with coagulant/polymer additions.
Characteristics:
Double filter belt: Circulate by two belts at top and bottom for fast and high rate dewatering.
Adjustable operating velocity from 1 m3/min to 9 m3/min.
Each high-press belt is equipped with tension controller to avoid uneven tension.
Sludge leveler: Keep the thickness of sludge even to enter the low-pressure rolls.
Low-pressure dewatering: Increasing the pressure by a stationary wedge to dewater after the discharging of free water and agglutinated water.
Low-pressure of gear-like rolling: Pressed by the gear-like rolls to discharge the surplus water.
Mid-pressure rolling of increasing pressure to remove moisture from the sludge flocs.
High-pressure shear rolling to press the gelatinous water by share forcing two filter belts.
Washing water can be reused and is adjustable to save up to 50% of washing water.
Belt alignment device can adjust the belt migration automatically.
Applications:
Municipal Wastewater.
Food Processing Wastewater.
Poultry and Slaughtering Waste.
Pulp & Paper Wastewater.
Petrochemical Wastewater. |
