ABSTRACT:
This invention relates to a backwash outlet assembly for a liquid particulate filter. The outlet is adapted to retain particles which comprise the filter medium while allowing backwash liquid together with impurities to discharge to waste. The outlet comprises an outlet weir, and a substantially non-turbulent flow zone located upstream of the weir. A particle return passage extends from the floor of the zone to the filter bed and means are included to at least restrict back flow in the passage. Filter media particles carried in suspension in the backwash liquid fall under the action of gravity to the floor of the zone and by the velocity of the backwash liquid into the entrance to the return passage. Preferably the particle return passage extends from the zone adjacent the weir and filter media particles trapped in the return passage are automatically conveyed back to the filter.
