Multi-Media Filtration

Multi-Media Filtration is a robust, industrial quality system to remove total suspended solids (TSS), turbidity, and silt density index (SDI): dirt, sand, and sediment. Abrasive suspended solids can easily damage plumbing, valves and downstream equipment. They will plug filters, foul reverse osmosis (RO) membranes, cause fouling and thermal efficiency loss, and harm boilers.

Technical Specifications

Feed water enters the vessel through an inlet valve and is sprayed out over a mixed media bed. The water then flows down through the bed. The coarse media layers trap large particles, and successively smaller particles are trapped in the finer layers of media.

The result is a highly efficient filtering system since suspended solids removal takes place throughout the entire bed. The clean water enters the distributor system at the bottom of the vessel and travels upward via the center riser tube, which is then piped out of the vessel.

Over time the media will trap additional solids resulting in an increased pressure drop across the vessel. Once the pressure drop reaches a preset level, the control system (or manual initiation) will trigger a backwash mode. 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 media. This increased velocity up through the bed disturbs the media and releases the trapped particles which are sent to a drain.
