HUBER Pile Cloth Media Filter RotaFilt®
The HUBER Pile Cloth Media Filter RotaFilt® is a compact, high-performance filter designed for fine filtration of wastewater. The filter uses a three-dimensional filter cloth that provides a very large active filtration surface, ensuring highly efficient removal of fine particles from the wastewater.
RotaFilt® is typically used for polishing after biological treatment, for water reuse applications, or as pre-treatment in plants incorporating quaternary treatment. Automatic operation, high effluent quality and robust construction make the filter well suited for both municipal and industrial wastewater treatment plants where stringent discharge requirements and high operational reliability are essential.

Benefits
The HUBER Pile Cloth Media Filter RotaFilt® combines high filtration efficiency with a compact design, enabling high hydraulic capacities within a limited footprint. The three-dimensional filter cloth effectively retains fine particles, even under varying loads and fluctuating flow conditions, ensuring stable and consistent effluent quality.
The filter is designed for continuous and reliable operation and is cleaned automatically via an integrated backwash system without interrupting normal operation. Filtration takes place at low head loss, contributing to low energy consumption and reduced operating costs over time. The robust stainless-steel construction ensures long service life and minimal maintenance, even under demanding wastewater conditions.
RotaFilt® is particularly well suited as pre-treatment for quaternary treatment, where stringent requirements are placed on water quality upstream of downstream processes such as ozonation or activated carbon adsorption.
