Carbon Columns - Sludge Dewatering Equipment

The carbon column is designed for an upward flow of filtrate. This carbon needs to be flooded at all times during the operation. The liquid is pumped into the bottom of the column, through the bottom filter screen. It then flows up through the carbon and out through the top filter screen.

Under normal operating conditions, one 200-225 pound charge will last four to five months before it needs replacement. This varies from installation to installation, due to different amounts of processed water and concentration of remaining contaminants.

The purpose of the Flex-O-Star Carbon Column is to remove residual color and organic material in the water coming from the vacuum pre-coat filter.
