The ROTODRUM is the opposite design of the Headworks ROTOSCREEN Gravity Sidehill Screen where the drum is stationary. Flow through is achieved by pump discharge pressure. Screenings are removed by an automated internal rotating mechanism. When differential pressure between inside and outside of the drum reaches the set point, the rotating mechanism is activated along with the screenings discharge valve to allow cleaning of the drum.

The ROTOFILTER (micro screen) can remove solids that are as tiny as 20 microns. It is applied in removal of suspended solids in secondary treated wastewater, algae, and silt. The ROTOFILTER is fully automated.
