Cochrane Activated Carbon Filtration
Cochrane provides industrial quality filtration systems, primarily using carbon in various forms but may also include other media as required.
Low Pressure Drop Efficient Carbon Vessels
Feed water enters the vessel through an inlet valve and is sprayed out over the activated carbon bed. The water then flows down through the carbon. The highly porous granulated carbon fines absorb and adsorb chlorine, organics and impurities. The water enters the distributor system at the bottom of the vessel and travels upward via the center riser tube where it is then piped out of the vessel.
Over time, the carbon will trap solids resulting in an increased pressure drop across the vessel which may will trigger the need for a backwash. During backwash the flow is reversed and the feed water enters down through the riser tube, exits out the distributor system and flows upward through the bed of carbon. This increased velocity up through the bed disturbs the carbon and releases the trapped particles which are sent to a drain.
