How It Works

Contaminated liquid "percolates" by gravity through the media, leaving behind the suspended solids. There is more head pressure available to "push" the liquid through the media as solids are deposited. The solids are then scraped from the surface of the rolled media as the media exits the deep bed and drops into a sludge hopper for disposal.

The Optimal DBG models run 24/7, with a low power consumption. Since no fabric filters are used, the filter never needs to be changed out. The DBG models handle extremely dirty water and liquids.


Optional Squeezer Attachment

The Squeezer Attachment regulates the pressure of the rollers, limiting the moisture content in the solids discharge.
