Cone Filters for Wastewater Treatment

Cone Filters are used to catch and filter any type of debris from a waste stream. A variety of mesh screens are available to remove micron-sized particulates as well as larger, 1/4″ sized particles. The cone filter has been highly successful in many applications such as pumping from wells and sump pumps.

System Overview

Cone Filter Technology contains a stainless steel screen filter that is designed for the removal of sand and sediment from well water. Our unique filter has grown popular due to its low maintenance design, stainless steel construction, space saving profile, and exceptionally low pressure loss.
All models of the Cone Filter series will operate with less than a 1-PSI pressure loss at maximum flow when clean. This efficiency provides real energy savings when compared to filter products that rely on energy consuming devices like spinners and torpedoes to give a comparable cleaning action.

Choosing a filter with sufficient surface area is critical in any application. The Cone Filter series has significantly more surface area than most traditional basket and y-strainers. Ecologix has a filter that will fit your specific needs with units available from 2″ to 10″ and flow rates up to 2,000 GPM (higher flow rates are achieved by manifolding multiple filters). Our screen mesh options are available from 16 to 250 mesh.

Pressure Differential Alarm Package (PDA)

To enhance our Cone Filter line of unique strainers, Ecologix has an Instrumentation Package that will monitor your differential pressure and will automatically backflush your strainer over a period of time.

The Pressure Differential Alarm Package (PDA) continously monitors the inlet and outlet system pressure. When the filter screen becomes dirty, a switch-gauge triggers an aubible siren and visual flashing alarm. These alarms are intended to alert maintenance personnel that the strainer screen needs to be removed from the strainer housing for manual cleaning.

The Automatic Timer Flush Package (ATF-EA-1.5) ensures that particulates that fall down into the debris reservoir are automatically flushed. The power supply and timer controls for the valve package are housed inside the watertight control box, attached to the valve. Depending on the application, the end-user simply dials in the flush frequency and flush duration of the valve. Based on the programmed parameters, the ball valve quickly opens and closes, minimizing the volume of water that is flushed from the strainer. The valve also comes with a manual flush control switch that can be used to conveniently manually flush the strainer or drain the strainer before removing the screen.
