HRD filters offer high-performance filtration in difficult process applications. The flux rate is typically 5 – 20 gpm/ft2. The HRD filter has a proven distribution design to enable excellent hydraulic coverage during high-rate operation. The media bed is similar to that of a conventional filter, except that the high velocity can drive the solids deeper into the media bed, enabling HRD filters to handle higher solids loadings and extended run cycles.
