The Filter Judge was designed with the municipal water industry in mind, but it can be used by many other operators of similar gravity filter units. This could mean that paper mills, petrochemical, manufacturers, and many others can benefit from the use of the Filter Judge. We have even sold our unit for use in pressure filters.
The Filter Judge is a tool for taking a vertical core sample of media (sand, anthracite, garnet, etc.) from a filter in a water treatment faciltiy.
