Vacuum filtration for large suspension volumes
For high-volume slurry filtration, streamline your process with a rotary disc filter that optimizes efficiency by reducing pressure losses, ensuring minimal maintenance and continuous, reliable operation.
Filters and Dewaters Suspensions Efficiently
The BoVac Disc Filter from BOKELA is a robust vacuum filtration solution designed to handle large-scale dewatering tasks across a range of industries including alumina refineries, coal processing, and fertilizers. Its unique design uses rotating disc technology to effectively separate and dewater suspensions, yielding end-products such as aluminum oxide and metallurgical coal. BoVac Disc Filters offer filter areas up to 352 m² per unit, allowing for substantial throughput in continuous operations. Equipped with fiber-reinforced polymer segments, they ensure easy maintenance with minimal downtime. Fully automatic operation and flexible process adaptation make this filtration system ideal for integration into existing production lines, reducing energy consumption through optimized hydraulic performance. Additionally, they feature large trapezoidal filtrate pipes for superior hydraulic efficiency and minimal pressure loss, culminating in high operational reliability and low operating costs.
