In the realm of environmental and water treatment, efficient sludge dewatering is a critical process for minimizing waste volume and maximizing resource recovery. The Gravity Belt Thickener (GBT) emerges as a reliable and sustainable solution for achieving these goals.
What is a Gravity Belt Thickener?
A GBT is a mechanical dewatering device that utilizes a porous filter belt to facilitate gravity drainage of water from sludge. It essentially works like a conveyor belt with a permeable surface that allows water to pass through while retaining the solid sludge particles.
Key Components and Working Mechanism:
A typical GBT comprises the following components:
