Abstract
A baffle system is described that significantly reduces media loss caused by turbulence encountered during gas and liquid backwashing of a discrete media filter bed. When positioned about a filter collection trough or outlet, the baffle system deflects rising gas bubbles away from the collection trough and disengages filter media from the backwash liquid.
