Belt Filter Press

With its unique concentration and dehydration design, the belt filter press has become the core equipment for dealing with the problem of low-concentration, high-fluidity sludge treatment in the context of continuous innovation of sewage treatment technology and upgrading of resource utilization needs. This type of equipment integrates the concentration, conditioning, and dehydration processes that need to be completed step by step in the traditional process into a continuous operation process through equipment optimization of mechanical structure and fluid mechanics. It is suitable for the treatment of residual sludge produced by processes such as A/O method and SBR method, showing significant technological breakthroughs and environmental protection value.

The core advantage of the belt thickener and dehydrator lies in its dynamic concentration and dehydration mechanism. The porous filter belt configured at the front end of the equipment completes the initial concentration of the sludge through the gravity dehydration section. The sludge that has not passed through the thickening tank removes free water at this stage to form a semi-solid substance with fluidity. The unique "wedge-shaped pre-pressure" structure then applies increasing pressure to the sludge, realizes shear extrusion through the angle area formed by the upper and lower filter belts, destroys the sludge colloidal structure and releases bound water, laying a physical foundation for subsequent high-pressure dehydration.

In view of the adaptability of different treatment scenarios, the equipment achieves functional differentiation through a modular concentration structure. This structural difference is not only reflected in the treatment scale, but also through the coordination of intelligent devices and pressure feedback systems, the filter belt operation parameters are dynamically adjusted to ensure the precise adaptation of different sludge properties. In terms of environmental benefits, the belt thickener and dehydrator significantly reduces environmental risks through fully enclosed operation and energy recovery design.

The belt filter press is leaping from a single device to a systematic solution. Its technology not only breaks the technical bottleneck of low-concentration sludge treatment, but also injects continuous momentum into the intelligent and resource-based transformation of the water environment management industry through the integration of the industrial chain.
