In a belt filter press, increasing the belt tension results in what effect?

In a belt filter press, increasing the belt tension primarily leads to a higher percentage of total solids being removed. This is because the greater tension on the belts enhances the pressure applied to the sludge being processed. When pressure increases, it helps to squeeze out more water, allowing more solids to be retained in the final product. This results in drier cake being produced, indicating efficient solid removal.

While other factors like belt life, sludge conditioning, and hydraulic loading may be affected by belt tension, the most significant and direct outcome of increased tension is the improvement in the solid removal efficiency. This effect is essential for optimizing the operation of a belt filter press in wastewater treatment processes, as achieving a high percentage of solids removed is crucial for effective sludge management.
