Reliable Paper Industry Machinery Disc Filter

The disc filter is an essential industrial paper machine designed for white water recovery and pulp thickening in paper manufacturing processes. This paper mill plant machinery achieves high fiber recovery rates from white water, enabling effective water recycling that reduces fresh water consumption and minimizes effluent discharge. When used for pulp thickening, the disc filter delivers outstanding outlet consistency, producing concentrated pulp suitable for storage or further processing.

The disc filter incorporates excellent filter disc structure that provides large effective filtering area, superior filtering effect, and easy maintenance. A special wear-resistant material distribution valve ensures reliable sealing and consistent performance over extended operation. The compact design of the disc filter delivers large production capacity while occupying minimal floor space. With complete equipment models and specifications, the disc filter can be configured with different filter areas to match various production capacities, delivering excellent economic and social benefits. The disc filter’s effective white water recovery and pollution reduction capabilities make it an environmentally sustainable choice for modern paper mills.
